Degree: Ph.D.
Thesis title: 'n Bydrae tot die nie-kommutatiewe ideaalteorie [Contribution to a non-commutative theory of ideals].
University: Potchefstroomse Universiteit (South Africa).
Advisor: Hendrik Schutte.
Biographical Data: He worked at the Technological University Delft in The Netherlands, and Potchefstroomse Universiteit, the Rand Afrikaans University, and the University of Stellenbosch in South Africa. He has published around 40 papers including Contributions to ideal theory in general rings (1964), Prime ideals and nil radicals in near-rings (1964), On the Levitzki nil radical (1965), Matrix near-rings (1986), On group near-rings (1989), Homogeneous maps as piecewise endomorphisms (1992), A shrinking lemma for random forbidding context languages (2000), Bag context tree grammars (2008) and Necessary conditions for subclasses of random context languages (2013).
He was President of the South African Mathematical Society in 1987 and the following is a report on his presidential address: "In his Presidential Address, "Die Wiskundige en Politiek", delivered at the 1987-AGM of the South African Mathematical Society at Stellenbosch, van der Walt, briefly sketched the extent to which the South African mathematician in performing his task, had been affected by the political dispensation of the time. He mentioned that the number of countries to which we as South Africans scientist may not travel or in which we were just very unwelcome guests was steadily increasing.
The South African Mathematical Society belonged to the International Council of Scientific Unions through the International Mathematical Union, and the International Council of Scientific Unions prescribed that all conferences held under its auspices must be open to all without consideration of, amongst other things, citizenship, and that therefore such conferences may be held only in countries which are prepared to admit everyone to the conference concerned. But, not all conferences were held under the aegis of the International Council of Scientific Unions. Furthermore, even the attendance of International Council of Scientific Unions conferences were not without problems: Delays occurred in the issuing of visas, as when a passport with a valid visa was sent to the applicant by surface mail instead of airmail. Even in the 1980s a considerable number of foreign mathematicians still visited South Africa. The Visitor's Programme of the South African Mathematical Society was under pressure not only because prominent mathematicians refused on principle to come to South Africa, but also because those who did come sometimes found that this was regarded by their colleagues as a dubious action which drew criticism and had to be defended. The President was of the opinion that the attitude of the South African mathematicians under these circumstances should be to:
(i) raise their level of scientific practice - quality is always more difficult to ignore summarily; (ii) persevere and spare no effort to make their contribution worldwide; members were strongly advised to approach the South African International Council of Scientific Unions Secretariat for advice and assistance, especially in the case of International Council of Scientific Unions conferences; (iii) receive in South Africa as many visitors of high standing as possible; (iv) play a more active role in politics."
He died on 31 December 2008.
Wessel J. KOTZE
Country: South Africa
Year: 1964.
Degree: Ph.D.
Thesis title: Iterative Solution of Equations in Linear Topological Spaces.
University: McGill University (Canada).
Advisor: Hans Wilhelm Eduard Schwerdtfeger.
Biographical Data: He was awarded an M.Sc (1961) from McGill University, Canada, for the thesis On infinitely many algorithms for the solution of an analytic equation. An Abstract appeared in the Bulletin of the Canadian Mathematical Society with the following note: "It is not customary to abstract Master's theses for the Bulletin, but the Editors feel that there is sufficient originality here to justify a departure from the usual policy."
He worked at the University of Cape Town and Rhodes University, Grahamstown, South Africa. He published over 15 papers including Notes on numerical analysis. IV. On accelerating iteration procedures with superlinear convergence (1964), Approximately normal function algebras which are local (1980), Quasicoincidence and quasi-fuzzy Hausdorff (1986), Fuzzy sobriety and fuzzy Hausdorff (1997) and Lifting of sobriety concepts with particular reference to (L, M)-topological spaces (2003).
The following obituary was published by Rhodes University: "It is with sadness that we inform staff members of the death of Professor Emeritus Wesley Kotzé, former head of the department of Mathematics, Rhodes University. Professor Kotzé passed away at his home in Somerset West on Wednesday, 3rd May, 2017. He was 79 years old. Wessel Johannes Kotzé was born at Williston but grew up and attended school in Tulbagh, the only son of a music teacher as mother and the Town Clerk as father. After a brilliant matriculation pass, he attended Stellenbosch University and obtained B.Sc. (majoring in mathematics and chemistry), B.Sc. (Hons) and M.Sc. degrees in mathematics, cum laude. He was awarded his Ph.D. in mathematics at McGill University in Montreal, Canada where he taught for a while before returning to South Africa on accepting a post at the University of Cape Town.
In 1983, he was appointed by Rhodes University as head of the Department of Mathematics (Pure and Applied), a post he held until retiring at the end of 2003. During his time at Rhodes University, Prof Kotzé also served as the first Dean of Research, as University Orator and became the founder of the Rhodes University Mathematics Education Project. He was awarded a medal for the Advancement of Mathematics in South Africa by the South African Mathematical Society. He also served as the Managing Editor of 'Questiones Mathematicae', the accredited journal and official organ of the South African Mathematical Society. He was a prominent researcher achieving an NRF B rating.
Starting out as a "crisp" mathematician in the field of functional analysis, in which he had some good publications, his interest turned to "fuzzy" mathematics, especially fuzzy topology. At Rhodes University, he established a school of fuzzy mathematics in the department which became one of the top research institutes in the field. As a former student and colleague, Professor Mike Burton relates that "He knew every established fuzzy mathematician in the world. Literally. His many connections and organisational abilities rapidly grew the school and it produced many MSc and PhD graduates". Some of these are prominent mathematicians such as Prof Burton himself and Drs Tomasz Kubiak, Venkat Murali, Babington Makamba and Pavel Lubczonok. Dr Phetiwe Matutu-Mabizela, the first black woman to graduate with a Ph.D. in mathematics in South Africa, did her Master's degree with Prof Kotzé. His reputation also drew many prominent international mathematicians to visit Rhodes University.
Prof Kotzé also had a great love and knowledge of classical music and fine art. He was a long serving chairperson of the Grahamstown Music Society. Renowned for his discernment, he had a fabulous collection of paintings, prints, sculpture and ceramics of prominent South African and international artists as well as a superb collection of books and furnishings. After retirement, he returned to Cape Town and settled in Marina da Gama. He pursued his love of mathematics by teaching at the African Institute for Mathematical Sciences and of music by contributing to Classical Music Radio. During the last two years, he lived in Somerset West. He suffered from Parkinson's disease, but died suddenly, probably of a heart attack while in the company of dear friends who could assist and comfort him in that extreme hour of need. A liberal man of many gifts, Prof Kotzé made a number of close friends, some of whom were or are prominent artists, musicians and writers. He also, famously, was quick to perceive slights and did not suffer fools gladly: a recipe for a number of choice enemies as well."

Cricket performance measures: "Hoffie Lemmer currently holds an appointment as an Emeritus Professor at the University of Johannesburg. He studied at the University of Pretoria and obtained the B.Sc. (cum laude), M.Sc. (cum laude) and D.Sc. degrees at this university. He also started his academic career at the University of Pretoria as a lecturer and was subsequently promoted to senior lecturer at the same institution. In 1968 he was appointed as professor of statistics at the Rand Afrikaans University. His main research interest at the time was non-parametric statistics and he published more than thirty papers in international journals. He was involved in many consultation projects. He retired at the end of 2001, after which he was offered the position of Special Professor at the University of Johannesburg, in order to enable him to continue his research. Since his retirement his research has focused on the development of cricket performance measures. Thus far he has published eight research papers and many popular articles in this field."

The following is on the University of Cape Town website (dated 26 February 2008): "The publication of the 150th edition of the high school magazine Mathematical Digest was celebrated in the Department of Mathematics last week. Founded by Emeritus Professor John Webb in 1971, the magazine has appeared quarterly without a break ever since. Way back then, Webb noticed that there was little on mathematics for children to read at school other than textbooks.
'It is strange because in other areas of school work, you watch movies on history, you read poetry and novels, you learn your language at home, you experience music and drama and art outside the school curriculum - but the learning of mathematics is entirely concentrated within the school curriculum,' he says.
Filling this gap, well over 3 000 articles have appeared in the 150 editions of Mathematical Digestsince 1971. They include readable articles on mathematics just outside the school curriculum, anecdotes of famous mathematicians from Pythagoras to Stephen Hawking, news of mathematical Olympiads, puzzles and problems with Sharp calculators offered as prizes.
Today, one copy of every edition of Mathematical Digest is sent free to 2000 high schools across South Africa, with support from the Old Mutual Foundation. With further support from the Western Cape Department of Education, all Dinaledi schools in the Western Cape receive ten copies of every edition."
S. G. REINACH
Country: South Africa
Year: 1966.
Degree: D.Sc.
Thesis title: Distribution-Free Methods in Experimental Design.
University: University of Pretoria (South Africa).
Advisor: David Johannes Stoker.
Biographical Data: He worked at the University of Port Elizabeth, South Africa. He published A nonparametric analysis for a multiway classification with one element per cell (1965), A distribution-free analysis of variance technique for block designs (1968) and Multiple testing procedures for the k-sample runs test (1976). We give the Summary of the 1976 paper: "In this paper simultaneous confidence intervals as well as multiple test procedures are derived for the number of runs in the k-sample runs problem. Some of these procedures depend on the upper alpha-point of the maximum of k equi-correlated unit normal random variables. Tables of critical values are constructed and presented. An application of these methods is illustrated by means of an example."
In this paper there is the following Acknowledgement: "Professors D J Stoker and N A S Crowther are thanked for some fruitful suggestions."

Paul Frank CHERENACK (d. 17.01.2002)
Country: South Africa
Year: 1968.
Degree: Ph.D.
Thesis title: Homotopy Groups of Algebraic Arcs Found by Smoothed Approximations.
University: University of Pennsylvania (USA).
Advisor: Andrew Hugh Wallace.
Biographical Data: He worked at Indiana University, Bloomington, Indiana, then at the University of Cape Town. He published around 40 papers including Basic objects for an algebraic homotopy theory (1972), Some topological functors arising from algebraic geometry (1977), Conditions for cubic spline interpolation on triangular elements (1984), Convenient affine algebraic varieties (1990), The left exactness of the smooth left Puppe sequence (1994), Frölicher versus differential spaces: a prelude to cosmology (2002), and Boman's theorem: Strengthened and applied (2005).
This last paper contains the following tribute: "Paul died after this paper was completed and before it was published. Paul is the primary author. A few brief words of tribute to Paul seems appropriate here. Paul Cherenack was a mathematician of international standing. Born and bred in Philadelphia, USA he attended the famous PENN (the University of Pennsylvania) where he obtained a broad and sound training in mathematics, studying for his Ph.D. in Algebraic Geometry with Andrew Wallace. After a year of research in Germany, where he met Marie-Anna, his wife to be, he came to Cape Town in 1974 to take a position at the University of Cape Town, liked what he saw, stayed and gave of his best to the University and to South Africa.
A true professional, Paul's encyclopaedic knowledge enabled him to teach in widely divergent areas. For years, accepting difficult assignments, he became a mainstay of the Department of Mathematics and Applied Mathematics. A steady stream of Masters and Doctoral students passed through his hands and he was always busy with new and creative work. He had an open door. Students and colleagues made use of it freely, receiving pertinent and friendly advice. Paul would go to special trouble with visiting scholars, taking them for walks and inviting them to his home. His Topologists' map of Cape Town, prepared for the Topology Conference of 1976, defined North as any direction perpendicular to the mountain contour in Rondebosch! A visitor to his home would find it filled with warm-hearted and endearingly eccentric people, scattered between the dogs, books and cats. However, when necessary, Paul could do the work of a builder and landscaper. In Tamboerskloof he laboured until he had changed the course of a mountain stream that threatened to undermine the foundations. A family man, Paul was proud of his attractive and intelligent daughters (Kuni and Genevieve) and he saw to it that they had the best he could provide. All in all, we have lost a good man and friend."

He is survived by his wife Henda (also an Emeritus Professor of Mathematics at the University of KwaZulu-Natal) and their children Christine, Sandra and Gustav. John Swart was born on 11 February 1940 in Kimberley. He grew up in Williston. His undergraduate studies and MSc were completed at Stellenbosch University. In 1969 he obtained his PhD under the supervision of Professor Hanno Rund (who was based at the University 0of South Africa at that time). John's lifelong and infectious enthusiasm for mathematics influenced the community in which he lived and worked for many decades.
His research concerned partial differential equations and biological mathematics. He was an active member of the South African Mathematical Society and served on its executive. He took an interest in local secondary schooling as well, delivering multiple talks at schools and meetings of mathematics teachers. John's association with the University of KwaZulu-Natal began when he was appointed as a lecturer at the former University of Durban-Westville in 1962. He took up a position at the former University of Natal (Durban) in 1965, where he served as Head of the Department of Mathematics and Applied Mathematics from 1980 to 1985. He served two further terms as Head of the School of Mathematical Sciences, from 1993 to 2000.
He gave very extensive service to the university through the Boards of Science and Engineering, as well as Senate, Council and countless university committees, culminating in a term as Pro-Vice Chancellor. He retired from the University of KwaZulu-Natal in 2005. John's vast experience, his forthright and articulate persona, and the breadth of his involvement in university affairs make him an unforgettable figure in the institution's history. As such he will be remembered fondly by colleagues young and old, and by generations of science and engineering students."

The Abstract of the 2013 paper reads: "Fuzzy relations are used to create partially ordered sets and lattices contained in this paper. Extensions of partially ordered sets and lattices are examined. The extensions studied include what are called canonical extensions and direct sums. Among the results is one showing that every cover function for a finitary distributive lattice is also a cover function for some nonfinitary distributive lattice. This result shows the necessity of the condition "finitary" that is used in an earlier result to prove the isomorphism of any two finitary distributive lattices which share a common cover function."

The Introduction to the second of these 1976 papers begins: "The topological and lattice-theoretical interpretations of the intuitionistic propositional calculus differ from the set algebraic interpretation of the classical two-valued propositional calculus in that, in the former cases, the intuitionistic propositional calculus is interpreted by means of classical theories which are definable in the second order classical predicate calculus, but, in the latter, the classical propositional calculus is interpreted by means of a classical theory which is definable in the monadic classical predicate calculus of the first order. The algebra of species is the intuitionistic analogy to the Boolean algebra of sets. The aim of this article is to give a species-algebraic interpretation of the intuitionistic propositional calculus analogous to the set-algebraic interpretation of the classical propositional calculus."
His last residence is given as San Jose, California, USA.

Thesis title: On the Design of Mixture Experiments.
University: University of London (UK).
Advisor: David Roxbee Cox.
Biographical Data: He studied for his doctorate at Imperial College, University of London. He gives the following Acknowledgement in his thesis: "I am deeply grateful to Professor D R Cox for suggesting the topic and for his guidance and encouragement in the preparation of this thesis. I wish to thank Dr A M Herzberg for invaluable discussion and help. Thanks are also due to Miss P A Mills for typing the thesis.
I wish to thank the firm British Petroleum for granting me the scholarship which made this research possible and the South African Department of Agricultural Technical Services for granting me leave of absence."
The Abstract of the thesis is as follows: "A mixture experiment is one in which the level of each quantitative factor in a particular treatment is a proportion of the total treatment. Because of these properties the factor space is a regular simplex with one less dimension than the number of factors.
The variance function of the expected mean response is examined in the 3-component case and under linear, quadratic and cubic mixture models. A function, utilising the generalised variance of the D-optimum design, is given whereby upper and lower bounds can be calculated for the maximum possible variance of the expected mean response for any given design space, design and model.
D-optimum designs, that is, designs with minimum generalised variances, were generated for the same design spaces and mathematical models. A generalisation is given for designing D-optimum experiments for a simplex design space of more than three components under a linear model.
A method was devised for designing mixture experiments that are as near D-optimum as possible for a given experiment size, design space and model. The method was tested on the same design spaces and models.
This last method was extended to enable incomplete block mixture experiments to be designed such that the generalised variance of the estimable parameters is minimised while at the same time minimising the effect of blocking on these estimations. Incomplete block mixture designs were generated for a number of block sizes and numbers of blocks when the design space is the 3-component full simplex and the above three mathematical models are used."

Degree: Ph.D.
Thesis title: The Elastic and Plastic Buckling of Circular Cylinders in Bending.
University: Cambridge University (UK).
Advisor: Christopher Reuben Calladine, FRS.
Biographical Data: He was born in South End, Port Elizabeth where he spent his childhood and early teenage years. He attended primary schools in Schauderville and South End, and the South End High School. When South End was declared a white area in terms of the Group Areas Act in 1965, his family, together with thousands of residents of this diverse and vibrant community, were uprooted and forcibly removed to racially designated group areas. With the extended-family general dealer business, established by his grandfather over thirty years before, now in ruins, Reddy's parents settled in Cape Town in 1968 after an aborted decision to immigrate to the United Kingdom. Daya, as he is popularly called, and his younger brother were sent to live with family members in Vrededorp, an area that was ironically to suffer the same fate as South End soon after.
After he matriculated from Lenasia Indian High School at the end of 1969, he enrolled for a degree in civil engineering at the University of Cape Town for which he had to obtain special ministerial permission. After he was awarded his degree in 1973 (with first-class honours), he took up a scholarship to Cambridge University where he graduated with a Ph.D. in 1977. After a year spent doing research at the University College, London, he returned to Cape Town to take up a joint lectureship in the Departments of Applied Mathematics and Civil Engineering at the University of Cape Town, a reflection of his established multi-disciplinary interests and work. He was appointed senior lecturer in 1982 and associate professor in 1985. In 1989 he was appointed Professor in Applied Mathematics and in 1999, Dean of the Faculty of Science.
He is the author of over 85 articles and also the author or co-author of three texts or monographs and three edited works. He holds fellowships of the Third World Academy of Sciences, the Royal Society of South Africa, the South African Academy of Engineering, and the University of Cape Town. He is also an elected member of the Academy of Science of South Africa.
He is married to Shaada Pillay, a librarian at the University of Cape Town. They have a son, Jordi who is an engineering student.
He has around 100 publications including Dual extremum principles in the dynamics of rigid perfectly plastic bodies undergoing finite deformations (1981), The obstacle problem for an elastoplastic body (1990), Acceleration waves in finitely deformed elastic-plastic solids (1995), Uniform convergence and a posteriori error estimators for the enhanced strain finite element method (2004), Computational model of soft tissues in the human upper airway (2012), Numerical approximation of variational inequalities arising in elastoplasticity (2014) and Multi-scale simulation of droplet-droplet interaction and coalescence (2018).

He married Annette Verhoef on 15 December 1973; they have three children: Helouise, Alewyn, and Elsa.
Here is the Abstract of his thesis: "A number of basic problems in non-parametric statistics are analysed, namely one-sample symmetry, two-sample shift and independence. The relevant test statistics are based on serial ranks and are by nature of serial ranks suitable for the sequential testing of hypothesis.
A class of fixed non-parametric test procedures are derived for the independence problem. The asymptotic distribution of the statistics are obtained under the hypothesis and contiguous alternatives by projecting the locally most powerful parametric test statistics into the class of linear serial rank statistics.
Concerning the symmetry and two-sample problems, invariance principles are derived for general regression statistics, which include the two-sample case, and statistics suitable for testing the hypothesis of symmetry. These invariance principles are derived under the hypothesis by direct application of the Lindeberg condition, under the assumption that the score function is increasing, continuous and square-integrable on (0, 1).
Under a further restriction, i.e. that the score function has a bounded second derivative, invariance principles for serial rank statistics are derived under fixed alternatives by making use of a further projection technique, originally used by Reynolds (1975) to obtain an invariance principle for a sequential test procedure for the hypothesis of symmetry.
An invariance principle is derived for a multi-stage test for symmetry based on serial ranks, from which analytic expressions are obtained for the values of the decision constants which were calculated empirically by other authors.
Finally Monte Carlo simulation results on various serial rank statistics provide an indication of the speed of convergence to the normal distribution."

Here is his own description of his experiences in the United States, "I came to the USA in 1988 knowing very little about the country and trusting the University of North Carolina, Chapel Hill, Mathematics department who invited me. But soon enough I find myself forced to go to the courts and to the American Mathematical Society Council to have my work and abilities recognized. My legal actions were settled in 1995, and in that year I was finally promoted to the rank of Associate Professor with tenure. As part of the settlement (may be to make up for all that had gone wrong) I was allowed to apply for promotion to Full Professor one year later. I was promoted to Full Professor after a full review on 1 July 1996. I then became the first black mathematician to be a tenured associate professor and the first to be promoted to the rank of Full professor at the oldest public university in the country (more than 200 years old).
I am certainly the only one in the history of the department to be promoted from Associate to Full professor in one year. The struggle is not over as mentalities are very difficult, if not impossible, to change and it is not easy to stay here. I used my struggle to open up the admission of Black graduate students in the department. I was told that there was only one Black student in the entire history of the department who got a Ph.D. and it was before I came to Chapel Hill. There are now 3 Black graduate students in the department preparing for a Masters and a Ph.D."

Degree: Ph.D.
Thesis title: 'n Bydrae tot die nie-kommutatiewe ideaalteorie [Contribution to a non-commutative theory of ideals].
University: Potchefstroomse Universiteit (South Africa).
Advisor: Hendrik Schutte.
Biographical Data: He worked at the Technological University Delft in The Netherlands, and Potchefstroomse Universiteit, the Rand Afrikaans University, and the University of Stellenbosch in South Africa. He has published around 40 papers including Contributions to ideal theory in general rings (1964), Prime ideals and nil radicals in near-rings (1964), On the Levitzki nil radical (1965), Matrix near-rings (1986), On group near-rings (1989), Homogeneous maps as piecewise endomorphisms (1992), A shrinking lemma for random forbidding context languages (2000), Bag context tree grammars (2008) and Necessary conditions for subclasses of random context languages (2013).
He was President of the South African Mathematical Society in 1987 and the following is a report on his presidential address: "In his Presidential Address, "Die Wiskundige en Politiek", delivered at the 1987-AGM of the South African Mathematical Society at Stellenbosch, van der Walt, briefly sketched the extent to which the South African mathematician in performing his task, had been affected by the political dispensation of the time. He mentioned that the number of countries to which we as South Africans scientist may not travel or in which we were just very unwelcome guests was steadily increasing.
The South African Mathematical Society belonged to the International Council of Scientific Unions through the International Mathematical Union, and the International Council of Scientific Unions prescribed that all conferences held under its auspices must be open to all without consideration of, amongst other things, citizenship, and that therefore such conferences may be held only in countries which are prepared to admit everyone to the conference concerned. But, not all conferences were held under the aegis of the International Council of Scientific Unions. Furthermore, even the attendance of International Council of Scientific Unions conferences were not without problems: Delays occurred in the issuing of visas, as when a passport with a valid visa was sent to the applicant by surface mail instead of airmail. Even in the 1980s a considerable number of foreign mathematicians still visited South Africa. The Visitor's Programme of the South African Mathematical Society was under pressure not only because prominent mathematicians refused on principle to come to South Africa, but also because those who did come sometimes found that this was regarded by their colleagues as a dubious action which drew criticism and had to be defended. The President was of the opinion that the attitude of the South African mathematicians under these circumstances should be to:
(i) raise their level of scientific practice - quality is always more difficult to ignore summarily; (ii) persevere and spare no effort to make their contribution worldwide; members were strongly advised to approach the South African International Council of Scientific Unions Secretariat for advice and assistance, especially in the case of International Council of Scientific Unions conferences; (iii) receive in South Africa as many visitors of high standing as possible; (iv) play a more active role in politics."
He died on 31 December 2008.
Wessel J. KOTZE
Country: South Africa
Year: 1964.
Degree: Ph.D.
Thesis title: Iterative Solution of Equations in Linear Topological Spaces.
University: McGill University (Canada).
Advisor: Hans Wilhelm Eduard Schwerdtfeger.
Biographical Data: He was awarded an M.Sc (1961) from McGill University, Canada, for the thesis On infinitely many algorithms for the solution of an analytic equation. An Abstract appeared in the Bulletin of the Canadian Mathematical Society with the following note: "It is not customary to abstract Master's theses for the Bulletin, but the Editors feel that there is sufficient originality here to justify a departure from the usual policy."
He worked at the University of Cape Town and Rhodes University, Grahamstown, South Africa. He published over 15 papers including Notes on numerical analysis. IV. On accelerating iteration procedures with superlinear convergence (1964), Approximately normal function algebras which are local (1980), Quasicoincidence and quasi-fuzzy Hausdorff (1986), Fuzzy sobriety and fuzzy Hausdorff (1997) and Lifting of sobriety concepts with particular reference to (L, M)-topological spaces (2003).
The following obituary was published by Rhodes University: "It is with sadness that we inform staff members of the death of Professor Emeritus Wesley Kotzé, former head of the department of Mathematics, Rhodes University. Professor Kotzé passed away at his home in Somerset West on Wednesday, 3rd May, 2017. He was 79 years old. Wessel Johannes Kotzé was born at Williston but grew up and attended school in Tulbagh, the only son of a music teacher as mother and the Town Clerk as father. After a brilliant matriculation pass, he attended Stellenbosch University and obtained B.Sc. (majoring in mathematics and chemistry), B.Sc. (Hons) and M.Sc. degrees in mathematics, cum laude. He was awarded his Ph.D. in mathematics at McGill University in Montreal, Canada where he taught for a while before returning to South Africa on accepting a post at the University of Cape Town.
In 1983, he was appointed by Rhodes University as head of the Department of Mathematics (Pure and Applied), a post he held until retiring at the end of 2003. During his time at Rhodes University, Prof Kotzé also served as the first Dean of Research, as University Orator and became the founder of the Rhodes University Mathematics Education Project. He was awarded a medal for the Advancement of Mathematics in South Africa by the South African Mathematical Society. He also served as the Managing Editor of 'Questiones Mathematicae', the accredited journal and official organ of the South African Mathematical Society. He was a prominent researcher achieving an NRF B rating.
Starting out as a "crisp" mathematician in the field of functional analysis, in which he had some good publications, his interest turned to "fuzzy" mathematics, especially fuzzy topology. At Rhodes University, he established a school of fuzzy mathematics in the department which became one of the top research institutes in the field. As a former student and colleague, Professor Mike Burton relates that "He knew every established fuzzy mathematician in the world. Literally. His many connections and organisational abilities rapidly grew the school and it produced many MSc and PhD graduates". Some of these are prominent mathematicians such as Prof Burton himself and Drs Tomasz Kubiak, Venkat Murali, Babington Makamba and Pavel Lubczonok. Dr Phetiwe Matutu-Mabizela, the first black woman to graduate with a Ph.D. in mathematics in South Africa, did her Master's degree with Prof Kotzé. His reputation also drew many prominent international mathematicians to visit Rhodes University.
Prof Kotzé also had a great love and knowledge of classical music and fine art. He was a long serving chairperson of the Grahamstown Music Society. Renowned for his discernment, he had a fabulous collection of paintings, prints, sculpture and ceramics of prominent South African and international artists as well as a superb collection of books and furnishings. After retirement, he returned to Cape Town and settled in Marina da Gama. He pursued his love of mathematics by teaching at the African Institute for Mathematical Sciences and of music by contributing to Classical Music Radio. During the last two years, he lived in Somerset West. He suffered from Parkinson's disease, but died suddenly, probably of a heart attack while in the company of dear friends who could assist and comfort him in that extreme hour of need. A liberal man of many gifts, Prof Kotzé made a number of close friends, some of whom were or are prominent artists, musicians and writers. He also, famously, was quick to perceive slights and did not suffer fools gladly: a recipe for a number of choice enemies as well."

Founded by Emeritus Professor John Webb in 1971, the magazine has appeared quarterly without a break ever since. Way back then, Webb noticed that there was little on mathematics for children to read at school other than textbooks.
'It is strange because in other areas of school work, you watch movies on history, you read poetry and novels, you learn your language at home, you experience music and drama and art outside the school curriculum - but the learning of mathematics is entirely concentrated within the school curriculum,' he says.
Filling this gap, well over 3 000 articles have appeared in the 150 editions of Mathematical Digestsince 1971. They include readable articles on mathematics just outside the school curriculum, anecdotes of famous mathematicians from Pythagoras to Stephen Hawking, news of mathematical Olympiads, puzzles and problems with Sharp calculators offered as prizes.
Today, one copy of every edition of Mathematical Digest is sent free to 2000 high schools across South Africa, with support from the Old Mutual Foundation. With further support from the Western Cape Department of Education, all Dinaledi schools in the Western Cape receive ten copies of every edition."
S. G. REINACH
Country: South Africa
Year: 1966.
Degree: D.Sc.
Thesis title: Distribution-Free Methods in Experimental Design.
University: University of Pretoria (South Africa).
Advisor: David Johannes Stoker.
Biographical Data: He worked at the University of Port Elizabeth, South Africa. He published A nonparametric analysis for a multiway classification with one element per cell (1965), A distribution-free analysis of variance technique for block designs (1968) and Multiple testing procedures for the k-sample runs test (1976). We give the Summary of the 1976 paper: "In this paper simultaneous confidence intervals as well as multiple test procedures are derived for the number of runs in the k-sample runs problem. Some of these procedures depend on the upper alpha-point of the maximum of k equi-correlated unit normal random variables. Tables of critical values are constructed and presented. An application of these methods is illustrated by means of an example."
In this paper there is the following Acknowledgement: "Professors D J Stoker and N A S Crowther are thanked for some fruitful suggestions."

Year: 1968.
Degree: Ph.D.
Thesis title: Homotopy Groups of Algebraic Arcs Found by Smoothed Approximations.
University: University of Pennsylvania (USA).
Advisor: Andrew Hugh Wallace.
Biographical Data: He worked at Indiana University, Bloomington, Indiana, then at the University of Cape Town. He published around 40 papers including Basic objects for an algebraic homotopy theory (1972), Some topological functors arising from algebraic geometry (1977), Conditions for cubic spline interpolation on triangular elements (1984), Convenient affine algebraic varieties (1990), The left exactness of the smooth left Puppe sequence (1994), Frölicher versus differential spaces: a prelude to cosmology (2002), and Boman's theorem: Strengthened and applied (2005).
This last paper contains the following tribute: "Paul died after this paper was completed and before it was published. Paul is the primary author. A few brief words of tribute to Paul seems appropriate here. Paul Cherenack was a mathematician of international standing. Born and bred in Philadelphia, USA he attended the famous PENN (the University of Pennsylvania) where he obtained a broad and sound training in mathematics, studying for his Ph.D. in Algebraic Geometry with Andrew Wallace. After a year of research in Germany, where he met Marie-Anna, his wife to be, he came to Cape Town in 1974 to take a position at the University of Cape Town, liked what he saw, stayed and gave of his best to the University and to South Africa.
A true professional, Paul's encyclopaedic knowledge enabled him to teach in widely divergent areas. For years, accepting difficult assignments, he became a mainstay of the Department of Mathematics and Applied Mathematics. A steady stream of Masters and Doctoral students passed through his hands and he was always busy with new and creative work. He had an open door. Students and colleagues made use of it freely, receiving pertinent and friendly advice. Paul would go to special trouble with visiting scholars, taking them for walks and inviting them to his home. His Topologists' map of Cape Town, prepared for the Topology Conference of 1976, defined North as any direction perpendicular to the mountain contour in Rondebosch! A visitor to his home would find it filled with warm-hearted and endearingly eccentric people, scattered between the dogs, books and cats. However, when necessary, Paul could do the work of a builder and landscaper. In Tamboerskloof he laboured until he had changed the course of a mountain stream that threatened to undermine the foundations. A family man, Paul was proud of his attractive and intelligent daughters (Kuni and Genevieve) and he saw to it that they had the best he could provide. All in all, we have lost a good man and friend."

The Abstract of the 2013 paper reads: "Fuzzy relations are used to create partially ordered sets and lattices contained in this paper. Extensions of partially ordered sets and lattices are examined. The extensions studied include what are called canonical extensions and direct sums. Among the results is one showing that every cover function for a finitary distributive lattice is also a cover function for some nonfinitary distributive lattice. This result shows the necessity of the condition "finitary" that is used in an earlier result to prove the isomorphism of any two finitary distributive lattices which share a common cover function."

The Introduction to the second of these 1976 papers begins: "The topological and lattice-theoretical interpretations of the intuitionistic propositional calculus differ from the set algebraic interpretation of the classical two-valued propositional calculus in that, in the former cases, the intuitionistic propositional calculus is interpreted by means of classical theories which are definable in the second order classical predicate calculus, but, in the latter, the classical propositional calculus is interpreted by means of a classical theory which is definable in the monadic classical predicate calculus of the first order. The algebra of species is the intuitionistic analogy to the Boolean algebra of sets. The aim of this article is to give a species-algebraic interpretation of the intuitionistic propositional calculus analogous to the set-algebraic interpretation of the classical propositional calculus."
His last residence is given as San Jose, California, USA.

Dirk Jacobus VAN-SCHALKWYK
Country: South Africa
Year: 1971.
Degree: Ph.D.
Thesis title: On the Design of Mixture Experiments.
University: University of London (UK).
Advisor: David Roxbee Cox.
Biographical Data: He studied for his doctorate at Imperial College, University of London. He gives the following Acknowledgement in his thesis: "I am deeply grateful to Professor D R Cox for suggesting the topic and for his guidance and encouragement in the preparation of this thesis. I wish to thank Dr A M Herzberg for invaluable discussion and help. Thanks are also due to Miss P A Mills for typing the thesis.
I wish to thank the firm British Petroleum for granting me the scholarship which made this research possible and the South African Department of Agricultural Technical Services for granting me leave of absence."
The Abstract of the thesis is as follows: "A mixture experiment is one in which the level of each quantitative factor in a particular treatment is a proportion of the total treatment. Because of these properties the factor space is a regular simplex with one less dimension than the number of factors.
The variance function of the expected mean response is examined in the 3-component case and under linear, quadratic and cubic mixture models. A function, utilising the generalised variance of the D-optimum design, is given whereby upper and lower bounds can be calculated for the maximum possible variance of the expected mean response for any given design space, design and model.
D-optimum designs, that is, designs with minimum generalised variances, were generated for the same design spaces and mathematical models. A generalisation is given for designing D-optimum experiments for a simplex design space of more than three components under a linear model.
A method was devised for designing mixture experiments that are as near D-optimum as possible for a given experiment size, design space and model. The method was tested on the same design spaces and models.
This last method was extended to enable incomplete block mixture experiments to be designed such that the generalised variance of the estimable parameters is minimised while at the same time minimising the effect of blocking on these estimations. Incomplete block mixture designs were generated for a number of block sizes and numbers of blocks when the design space is the 3-component full simplex and the above three mathematical models are used."

Biographical Data: He was born in South End, Port Elizabeth where he spent his childhood and early teenage years. He attended primary schools in Schauderville and South End, and the South End High School. When South End was declared a white area in terms of the Group Areas Act in 1965, his family, together with thousands of residents of this diverse and vibrant community, were uprooted and forcibly removed to racially designated group areas. With the extended-family general dealer business, established by his grandfather over thirty years before, now in ruins, Reddy's parents settled in Cape Town in 1968 after an aborted decision to immigrate to the United Kingdom. Daya, as he is popularly called, and his younger brother were sent to live with family members in Vrededorp, an area that was ironically to suffer the same fate as South End soon after.
After he matriculated from Lenasia Indian High School at the end of 1969, he enrolled for a degree in civil engineering at the University of Cape Town for which he had to obtain special ministerial permission. After he was awarded his degree in 1973 (with first-class honours), he took up a scholarship to Cambridge University where he graduated with a Ph.D. in 1977. After a year spent doing research at the University College, London, he returned to Cape Town to take up a joint lectureship in the Departments of Applied Mathematics and Civil Engineering at the University of Cape Town, a reflection of his established multi-disciplinary interests and work. He was appointed senior lecturer in 1982 and associate professor in 1985. In 1989 he was appointed Professor in Applied Mathematics and in 1999, Dean of the Faculty of Science.
He is the author of over 85 articles and also the author or co-author of three texts or monographs and three edited works. He holds fellowships of the Third World Academy of Sciences, the Royal Society of South Africa, the South African Academy of Engineering, and the University of Cape Town. He is also an elected member of the Academy of Science of South Africa.

Here is the Abstract of his thesis: "A number of basic problems in non-parametric statistics are analysed, namely one-sample symmetry, two-sample shift and independence. The relevant test statistics are based on serial ranks and are by nature of serial ranks suitable for the sequential testing of hypothesis.
A class of fixed non-parametric test procedures are derived for the independence problem. The asymptotic distribution of the statistics are obtained under the hypothesis and contiguous alternatives by projecting the locally most powerful parametric test statistics into the class of linear serial rank statistics.
Concerning the symmetry and two-sample problems, invariance principles are derived for general regression statistics, which include the two-sample case, and statistics suitable for testing the hypothesis of symmetry. These invariance principles are derived under the hypothesis by direct application of the Lindeberg condition, under the assumption that the score function is increasing, continuous and square-integrable on (0, 1).
Under a further restriction, i.e. that the score function has a bounded second derivative, invariance principles for serial rank statistics are derived under fixed alternatives by making use of a further projection technique, originally used by Reynolds (1975) to obtain an invariance principle for a sequential test procedure for the hypothesis of symmetry.
An invariance principle is derived for a multi-stage test for symmetry based on serial ranks, from which analytic expressions are obtained for the values of the decision constants which were calculated empirically by other authors.
Finally Monte Carlo simulation results on various serial rank statistics provide an indication of the speed of convergence to the normal distribution."

Here is his own description of his experiences in the United States, "I came to the USA in 1988 knowing very little about the country and trusting the University of North Carolina, Chapel Hill, Mathematics department who invited me. But soon enough I find myself forced to go to the courts and to the American Mathematical Society Council to have my work and abilities recognized. My legal actions were settled in 1995, and in that year I was finally promoted to the rank of Associate Professor with tenure. As part of the settlement (may be to make up for all that had gone wrong) I was allowed to apply for promotion to Full Professor one year later. I was promoted to Full Professor after a full review on 1 July 1996. I then became the first black mathematician to be a tenured associate professor and the first to be promoted to the rank of Full professor at the oldest public university in the country (more than 200 years old).
I am certainly the only one in the history of the department to be promoted from Associate to Full professor in one year. The struggle is not over as mentalities are very difficult, if not impossible, to change and it is not easy to stay here. I used my struggle to open up the admission of Black graduate students in the department. I was told that there was only one Black student in the entire history of the department who got a Ph.D. and it was before I came to Chapel Hill. There are now 3 Black graduate students in the department preparing for a Masters and a Ph.D."
