**Enrique Planchart**worked at Simón Bolívar University in Venezuela for 47 years, first as a professor of mathematics, then as rector of the university. He fought for improvements in mathematical education, and was praised as a "defender of democracy, the University and youth".

### Biography

**Enrique Planchart**was the son of Enrique Planchart Loynaz (1894-1953) and Luisa Rotundo Blanco (1897-1952). The Planchart family originally came from Catalonia, Spain, and it reached Venezuela when two Planchart brothers arrived there in around 1848. Enrique Planchart Loynaz had studied at a school run by French fathers in Caracas, and 1912 had been one of the founders of the Círculo de Bellas Artes, a group of landscape artists and writers. A poet and critic, he was later head of the Ministry of Education and of the Venezuelan National Library. Luisa Rotundo Blanco was a pianist and harpsichordist. Enrique Planchart Loynaz and his wife had two sons, Alejandro Enrique Planchart (1935-2019) and Enrique Aurelio Planchart (1937-2021), the subject of this biography. Let us note that the Planchart family was large, loving, musical and culturally prominent. Luis Xavier Grisanti writes [11]:-

His uncle, the playwright and novelist, Julio Planchart, was a member of the National Academy of History and ambassador of Venezuela in Chile. The home of his grandparents, Enrique Planchart Ruiz and Soledad Loynaz, was a melting pot of culture, knowledge and Venezuelan identity.Enrique Planchart's elder brother, Alejandro Enrique Planchart, became one of the world's leading music scholars. He was, for many years, a professor in the Music Department of the University of California at Santa Barbara. We note here that Enrique Planchart had lost both his parents by the time he was sixteen years old.

Enrique Planchart attended the Colegio América in the San Bernardino area of Caracas. This school, which opened in 1939, had been founded by Spanish exiles and financed by the Caracas elite who wanted a secular school. At this school he had the mathematics teacher Ángel Palacio Gros who taught him from the 3rd year of his Baccalaureate. Ángel Palacio Gros was Spanish, had fought in the Spanish Civil War for the Republicans and was taken prisoner in 1938 after a defeat at the Battle of Teruel. Pressure from the Venezuelan government led to his release in 1947 and exile to Venezuela. Planchart writes in [16]:-

... I was lucky of having from the 3rd year of the Baccalaureate to the 2nd year of the University, Ángel Palacio Gros as professor of geometry.In fact the Colegio América had a strong link with the School of Physics and Mathematics in the Central University of Venezuela. This university in Caracas was founded in 1721 making it the oldest university in Venezuela and one of the oldest in the Americas. Ángel Palacio Gros began teaching at the Central University of Venezuela in 1948 but in 1951 he signed the manifesto against the revocation of the Organic Statute of National Universities and was dismissed. He returned to teaching at the Colegio América, becoming Planchart's teacher, but Palacio Gros was reinstated to his university position so when Planchart began his studies of mathematics at the Central University of Venezuela in Caracas he continued to be taught by Palacio Gros. We note that while at university in the late 1950s, Planchart met and became close friends with Gonzalo Pérez Iribarren. These two shared a passion for mathematics and they became friends for life.

The Faculty of Science was created in the Central University of Venezuela in 1958 and Planchart was present at the Act of Creation. He writes [16]:-

It was an Academic Act of great solemnity, presided over by the Rector Francisco de Venanzi. Without a doubt, this act marks a milestone in the history of Mathematics in Venezuela, it was the first Faculty of Sciences in the country and soon the first Mathematics graduates in Venezuela would graduate.In January 1962 Raimundo Chela became Head of the Department of Mathematics and Planchart describes being a student in the Department at this time [16]:-

... in the cafeteria of the Faculty of Humanities, behind Engineering, Raimundo Chela shared a table with several students from the School of Mathematics: José Masón, Federico Martin and myself. We drank coffee, sometimes several, and we talked. ... After jokes, comments about music or poetry and discussing politics (always politics for hours), the conversation would move to Mathematics: Number Theory or Galois Theory, most of the time. Also, frequently, stories and anecdotes about famous mathematicians.The Simón Bolívar University was opened in Caracas on 19 January 1970. It was developed with the aim of strengthening the economic and social state of the country and, with a high entry requirements, it has particular emphasis on sciences, mathematics, engineering, and humanities. Planchart became a a full-time contracted professor in the Department of Pure and Applied Mathematics of the University on 1 January 1973. He was Head of the Department of Mathematics and Computer Science from 10 October 1973 to 31 August 1980.

Planchart spent seven years as Head of the Department of Mathematics and Computer Science at Simón Bolívar University but he had never undertaken research for a Ph.D. He decided that he wanted to study for a doctorate and went to the University of California, Berkeley, where he undertook research advised by Alan David Weinstein. Weinstein, born in New York City in 1943, had been awarded a Ph.D. by the University of California, Berkeley in 1967 with a thesis supervised by Shiing-Shen Chern. He undertook research on differential geometry and had been a full professor since 1976. Planchart was awarded a Ph.D. in 1982 for his thesis

*Analogies in Symplectic Geometry of Some Results of Cartan in Representation Theory*. The Abstract to the thesis begins [15]:-

E Cartan proves in his paper: 'Sur la détermination d'un système orthogonal complet dans un espace de Riemann symétrique clos' Ⓣ, that the irreducible unitary representations of the group of isometries G of a Riemannian symmetric space appearing in the space of complex square integrable functions $U_{2}(M)$, are those for which the isotropy group H of a point leaves a vector fixed. He also proves that such a representation appears with multiplicity one. Given the connections between the theory of unitary representations of a Lie group G, and the theory of Ad*-equivariant Hamiltonian actions of G, established in the work of A Kirillov and B Kostant, the question arises as to whether these theorems of Cartan have an analogue in the other theory.Returning to the Simón Bolívar University, Planchart became coordinator of the Bachelor and Postgraduate Degrees in Mathematics, a position he held from 15 May 1983 to 16 June 1985.

The 7th Latin American School of Mathematics was held at the Simón Bolívar University 16-27 July 1984. Planchart delivered the course

*Geometría simpléctica*Ⓣ which was published as a 109-page book. José F Cariñena reviewed the book and writes [2]:-

These notes of a course given in Caracas in the 7th Latin American School of Mathematics are a simple introduction to symplectic geometry which can be useful for both physicists interested in an up-to-date presentation of classical mechanics and classical field theory and mathematicians with an interest in the applications of the modern tools of differential geometry to different branches of physics. It is written at the graduate student level, and after a general introduction of the basic definitions and theorems of symplectic geometry, such as for instance the Darboux-Weinstein theorem, as well as their applications to Hamiltonian systems, the author studies symplectic actions of Lie groups and the reduction technique for systems with symmetry. Finally, the last section is devoted to developing the Kirillov-Kostant-Souriau method of the orbits of the coadjoint action.Planchart directed the National Centre for the Improvement of Science Teaching (CENAMEC-USB) from 1989 to 1999. It is as a member of CENAMEC that he wrote the short paper

*Mapas*Ⓣ in 2004. The paper begins [18]:-

Man has seen the need to represent the Earth on a flat surface, which is given the name of a geographical chart or map. The problem with making a map of the Earth, or part of it, is to construct a bijection between part of the sphere and a plane. From experience we know that this cannot be done without breaking or deforming the sphere, and here lies the mathematical richness of the problem. We have to sacrifice some property or relationship in the sphere and what we sacrifice depends on what we want to do with the map. Ideally we would like an isometric map, which preserves all distances and geometric properties. Since this is not possible, we can be content with a map that preserves geodesics (a geodesic is the line that marks the shortest path between two points). On the sphere, the geodesics are the arcs of maximum circumference; in the plane, they are the line segments. A map produced by projection from the centre of the Earth onto a tangent plane preserves the geodesics.Although his early papers were on high level mathematics, his later publications were mostly on mathematical education. Here are samples of his papers:

*Geometría simpléctica*Ⓣ (1984);

*Geometría simpléctica y sistemas hamiltonianos completamente integrables*Ⓣ (1988);

*La Geometría de los Teoremas de Conmutatividad en Variedades Poissonianas de Dimensión Infinita*Ⓣ (1990);

*Enseñanza de la ciencia en Venezuela: un reto al futuro*Ⓣ (1995),

*Raimundo Chela*(2000);

*Programa Igualdad de Oportunidades-USB*Ⓣ (2003);

*Programa de Especialización en Didáctica de las Matemáticas en Educación Media-USB*Ⓣ (2003);

*Mapas*Ⓣ (2004);

*Educación matemática y formación de profesores: propuestas para Europa y Latinoamérica*Ⓣ (2005); and

*La enseñanza de la matemática en Venezuela, programa de didáctica de la Matemática para educación media*Ⓣ (2005).

He received awards for the high level mathematical papers he published up to 1990 [5]:-

Planchart's scientific work was recognised by the Venezuelan Academy of Physical, Mathematical and Natural Sciences, of which he was a Corresponding Member, as well as by the National Council for Scientific and Technological Research (Conicit) which in 1989 awarded him the Prize for Best Scientific Work in Mathematics, and in 1991 an honourable mention for this same award.In 2000, Planchart played the main role in setting up the Equal Opportunities Programme (Programa Igualdad de Oportunidades, PIO) and became its first coordinator. Alexander Bueno writes [1]:-

The PIO, his masterpiece as a socio-educational aid programme, has been the most important social responsibility programme in the Simón Bolívar University since its inception. This programme is born from the disproportion that the admission statistics of our university had been showing in relation to the proportion of students from public institutions admitted versus institutions from the private sector, reaching a proportion of 96% of students from private institutions in the late 1990s and 4% from the public sector. That was the main motivation for creating the PIO.Soraya Villarreal explains in [19] how Planchart built up the PIO:-

Professor Planchart's concern to contribute to improving education in the country originated a tour of more than 150 secondary education institutions located in the states of Miranda, La Guaira and the Capital District, looking for young people who wanted to study scientific-technological careers, and formed a work team that became a family, which not only remains united, but also continues to generate change in the secondary education institutions of the official sector through this programme.He continued his efforts to bring in changes to improve the way mathematics was being taught, particularly at secondary school level. He was the driving force behind the 'Specialisation in Didactics of Mathematics in Secondary Education', a postgraduate programme at the Simón Bolívar University. He wrote the paper [17] setting out his ideas:-

Currently, in the teaching of Mathematics in Venezuela, one of the main problems is the deficiency in the effective application of didactics that allows guaranteeing the success of the teaching-learning processes of Mathematics. This is even more evident in the subject of geometry, which is systematically omitted despite being in the contents of the programmes of the educational levels preceding the higher one. In addition, in recent years in the field of Mathematics Education there have been vertiginous changes that have forced us to review the situation of Mathematics and its teaching at different educational levels.Planchart was elected Rector of the Simón Bolívar University in July 2009 after an election in which he stood against the electrical engineer José Ferrer, who at that time was academic vice-rector. When elected, Planchart said [5]:-

Given this situation, it seems necessary to promote programmes that respond to the new innovative trends that have been emerging in the field of Mathematics Education, such as, among others, the impact of new technologies, modelling, new evaluation techniques, motivation, methodological changes towards the acquisition of the typical processes of mathematical thought, heuristics (problem solving) as a tool for teaching mathematics, etc. And some trends in mathematical content: a shift towards discrete mathematics, the impact of the content of modern calculation methods, the recovery of geometric thinking and spatial intuition, the rise of random thinking, of probability and statistics.

The University is threatened; the values of the University do not seem shared by those who administer the State in these times; they favour institutions that are not universities, that are training schools for people who are capable of carrying out specific tasks that may seem important at the moment, but who do not have, and will not have, the capacity to continue their self-training, to develop and adapt to changes in the world that are unstoppable.It was not long before the threats to the university that Planchart saw became very real indeed. The 2010 parliamentary election in Venezuela took place on 26 September 2010. In Venezuela the Plan República was a military deployment carried out during all electoral processes whose main purpose was to safeguard order and security during elections. In the early hours of the election day members of Plan República entered the Simón Bolívar University with long weapons, raiding the centre set up by Voto Joven, a youth group who argued for the extension of political rights to youth and the strengthening of democracy in Venezuela. The raiders had no search warrant, took away computers owned by Voto Joven, and violated the autonomy of the university.

...

the University has to remain open, it is a enormous sacrifice for all, we know. This so-called socialist government has made the university system only for a privileged group, for those who have transportation and can eat three times a day. We will be left with fewer students and fewer teachers, but we have to continue, because the opposite would be to bury the Simón Bolívar University.

Planchart was only supposed to serve as rector for a period of four years, 2009-2013. The government, however, suspended elections for university rectors, so he remained in office. In 2017 there was extraordinary political interference in the running of the university. Beginning in January 2017 there were protests throughout Venezuela when the government arrested many opposition leaders. The academic vice-rector of the Simón Bolívar University resigned and on 8 June 2017 the university presented two candidates, Oscar González and Solange Issa, to the National Council of Universities to fill the position. The minister for university education, science and technology, Hugbel Roa, ignored the university's opinion and proposed Luis Holder as a candidate. On 11 July the National Council of Universities appointed Luis Holder. Planchart wrote [3]:-

Holder has an unfortunate history at the Simón Bolívar University (he was a professor for a term in the nineties), his resumé shows that he has only held managerial positions, not academic ones, he has no thesis students, students or interns, he has no research activities, except for three articles of 1994 that he published when he finished his doctoral thesis. He has no scientific publications, he is not an academic. We explained to the National Council of Universities the academic, not political, reasons why Holder should not be appointed, as well as the community consultation process that produced the candidacies of Óscar González and Solange Issa. They are recognised professors who have the support of the entire University, professors, students, employees and workers.Holder took up the appointment on 7 September 2017 and Planchart announced that the University was making an appeal. The appeal failed and, despite student and staff protests, Holder continued to hold the position.

Planchart's health deteriorated but he made every effort to continue carrying out his duties. Luis Xavier Grisanti wrote [11]:-

During the COVID-19 pandemic, he helped promptly deliver virtual classes. At all times, he especially supported low-income students. He survived several strokes, without neglecting his duties as rector.On 27 July 2021, Planchart died leaving his wife, Isbelia Martin, and his children. At a meeting on 5 August 2021 in Simón Bolívar University to bid farewell and honour Planchart, Benjamin Scharifker, former Rector and Professor Emeritus of the University, gave a speech in which he spoke of the rigour with which Planchart had conducted his life [19]:-

A rigour that perhaps came from his mathematical training, but that beyond analysis and geometry gave him an extraordinary mastery of space and time to be able to develop a strategic vision that allowed him to carry out the many academic aspects he did throughout his life. A strategic thought that in the last years of his life he used for the benefit of the university, delivering his vision of the future until his last breath.Grisanti wrote [11]:-

In his messages to the university community, Rector Planchart tried to create awareness among the students about the challenges of the integral development of Venezuela in the framework of the great scientific and technological advances of Humanity and the III and IV Industrial Revolutions. Overcoming the rentier atavism of Venezuelan society was the object of his perennial concern and self-sacrificing pedagogical work. It remains for his colleagues and disciples to follow his legacy in favour of sustainable development and not rent-seeking in Venezuela. His dream of turning our country into a knowledge society in line with the most advanced nations in terms of scientific and technological development is about to come true.Alexander Bueno writes [1]:-

To speak of Professor Planchart, is to speak of a visionary, honest, ethical, responsible, good person, hardworking and very stubborn man, when something was in his head he did not stop until he achieved it. He felt love and passion for the projects he generated.Following Planchart's death, Luis Holder was appointed as rector of Simón Bolívar University. He had already acted in that capacity during times when Planchart had been too ill to carry out his duties.
