Biography

László Fuchs is the son of Dávid Rafael Fokos-Fuchs (1884-1977) and Teréz Rosenberg (1896-1974). Dávid Fokos-Fuchs had been born in Bzenec, Austro-Hungary but moved with his family to Bratislava in 1887. Graduating from Bratislava in 1902, he studied at the University of Budapest. In 1907 he was awarded a Hungarian-Latin-German teaching certificate and taught in Jewish schools in Budapest. Dávid Fokos-Fuchs and Teréz Rosenberg married in 1923. They had a son László Fuchs, the subject of this biography, born in 1924, and a daughter Edit Fuchs (1927-2004) who became a high school teacher of foreign languages. In [5] László Fuchs spoke about his parents:-
I cannot fail to recall with deep gratitude the memory of my parents. My mother succeeded in transplanting a fraction of the latent mathematical talent she inherited from her father. My father, a leading Finno-Ugric linguist, set an example (even in the absence of state recognition) of the sacrifice and selflessness of research and the importance of investigating fundamental scientific questions. His influence on my life is immeasurably greater than that of anyone else.
After a long struggle to set up a Jewish high school in Budapest, the Jewish Gymnasium began construction in 1913 and teaching began there in 1915. Both boys and girls studied there receiving excellent education from high quality teaching staff. Between 1933 and 1940 Dávid Fokos-Fuchs was the deputy director of the Jewish Gymnasium, between 1940 and 1942 he was its acting director, and between 1942 and 1948 its appointed director. László Fuchs studied at this Jewish Gymnasium and it was there, when he was about fourteen years old, that he became seriously interested in mathematics. László Fuchs writes [18]:-
At the beginning of the 1941-42 school year, Paul Erdős's father visited the principal [Dávid Fokos-Fuchs] of the Jewish Gymnasium in order to secure a classroom. The Jewish Cultural Association had organised a special course for high school students interested in mathematics, and needed a place to meet once a week. The instructor was Tibor Gallai, a very talented mathematician and a superb teacher (without a job). The school principal agreed, under one condition: his son (me) would also be admitted to the course. [There were] 8 or 10 students in the group. Most of us were in high school. Some had already graduated, but because of the numerus clausus (quota against Jews) weren't allowed to enter the university.

Before and after class we had long discussions on the solutions of the take-home problems, possible generalisations, and so on. ... [There were only a] few in the course who would survive the Holocaust.
After graduating from the Jewish Gymnasium, Fuchs applied to study mathematics and physics at the University of Budapest [5]:-
I was not accepted to the Budapest University of Technology because of the Jewish quota, but after six months of working in a factory I was allowed to enrol in the Faculty of Humanities as a teacher candidate majoring in mathematics and physics.
The Hungarian government had operated anti-Semitic policies and persecuted Jews from 1938. Fuchs' failure to be admitted to university is an example of this. In March 1944, Nazi Germany decided, for military reasons, to occupy their ally Hungary. Between April and July of that year Hungarian and German authorities divided Hungary into six operational zones, created transit ghettos in each and then began deportation of Jews. Fuchs' university career was dramatically interrupted when he was sent to a forced labour camp in Yugoslavia. He spoke in [5] about problems even after he was able to continue his university studies:-
In 1945, immediately after the war, it was not possible to study much mathematics at the University of Budapest. Professor Fejér grew weak during the German occupation. Professor Kerékjártó could no longer hold lectures due to his illness. The wartime suffering caused by military service, the terrible prisoner of war situation and inhuman labour did not break us.
Five of the students, János Aczél, Ákos Császár, László Fuchs, István Gál (Gaál) and János Horváth, were all outstanding mathematicians and all born in 1924. Fejér called them the "Big Five" and they decided to study serious mathematics together. Zsolt Páles, President of the Department of Mathematical Sciences of the Hungarian Academy of Sciences, said [5]:-
... the legendary meetings of the "Big Five" were different from ordinary seminar lectures, not only in that the members were constantly interjecting questions and ideas, but also in that they laughed and joked almost non-stop, where the subject of the joke was usually the topic being discussed or the way it was presented. "It was wonderful to learn some serious mathematics alongside all the jokes," said Páles, quoting Fuchs.
Fuchs graduated from Péter Pázmány University in 1946. This university, originally founded in 1635, was renamed Eötvös Loránd University in 1949, the name it retains to this day. He was awarded a Diploma from Eötvös Loránd University in 1947 which qualified him to teach Mathematics and Physics in Gymnasiums and, in the same year, he was awarded a Ph.D. for his thesis Quasi-Primary Ideals. He published a paper with the same title in 1947. It was reviewed by I S Cohen who writes:-
Let R be an integral domain with identity element. An ideal Q is defined to be quasi-primary if abQab \in Q implies that some power of a or of b is in Q; Q is quasi-primary if and only if its radical is prime. If R is Noetherian, then every ideal is the intersection of a finite set of quasi-primary ideals such that no proper subset has quasi-primary intersection. The numbers of quasi-primary components and their radicals are uniquely determined. The connection between this decomposition and those given by E Noether in 1921 is discussed.
This paper was one of four Fuchs published in 1947 under the name Ladislas Fuchs, the other three being: A new proof of an inequality of Hardy-Littlewood-Pólya; On relatively primary ideals; and Further generalization of the notion of relatively prime ideals.

Let us note that Fuchs was undertaking research in algebra despite Eötvös Loránd University having no experts in algebra on the staff at this time. The Big Five had largely supported each other as they worked in areas of their own choice. He did have occasional contact with the algebraist László Rédei but Rédei worked at Szeged University which was about 200 km from Budapest. We note that travel in Hungary in the aftermath of World War II was very difficult and Fuchs could only make a very occasional trip to Szeged. He wrote [15]:-
Julius König and Michael Bauer had a number of papers in classical algebra (the former even had a frequently quoted book), and Joseph Kürschák was the founder of classical valuation theory, but they died before World War II and did not have any followers. Abstract algebra was non-existent in Hungary. As a result, no guidance was available for students interested in abstract algebra; we had to learn it from books and articles. Undoubtedly, we benefited tremendously from the congenial, research-oriented atmosphere and the support of many established mathematicians, though the "abstract nonsense" was frowned upon by several application-oriented colleagues.
For the two years 1947-49 Fuchs taught at a Gymnasium in Budapest. In 1949 he was appointed as an assistant at Eötvös Loránd University. He was given the right to teach in 1951 and in 1952 he was made a Docent. His research output was exceptional and MathSciNet lists 39 papers he published by 1953. It was in 1953 that his achievements were recognised with a Kossuth Prize [19]:-
... for work on the theory of structural algebra.
Fuchs quickly gained a reputation as an outstanding lecturer [2]:-
The classrooms were always full, students went there to enjoy the beauty and clarity of his lectures. With his regular algebra seminars he started building up an "algebra school" from nothing. He never pushed his students to follow his special interest in algebra, but he rather helped them to develop their own field according to their characteristic abilities. ... His main mission was to serve the best interest of the students and mathematics, and to help young mathematicians in getting involved in research. He did not show the slightest opportunism, even in time when it was a means of survival. This was one of the main reasons that his administrative career was held back and eventually broken.
In 1954 he was awarded the degree of Doctor of Sciences and, in the same year, was appointed as a full professor at Eötvös Loránd University. Remarkably he was also involved in university administration acting as head of the Mathematical Institute in 1953-54 and dean of the Faculty of Mathematics, Physics and Chemistry from 1954 to 1957. In the middle of his time as dean, he had to cope with the events surrounding the Hungarian uprising which began in Budapest on 23 October 1956 when students protested at the Parliament Buildings. The revolution spread and on 4 November 1956 troops were sent to put down the revolution. The Soviet tanks entered Budapest and shot a cannon at the building containing Fuchs' apartment; his apartment was completely destroyed.

The year 1958 saw the publication of the book Abelian groups by Fuchs. B H Neumann writes [28]:-
Professor Fuchs has packed a very great amount of important and interesting group theory into it; he always explains what he intends to do, and why; he not only proves theorems but also discusses their significance.
R A Beaumont writes [3]:-
The author has been eminently successful in giving a complete, detailed, and easily understandable account of the present status of the theory of abelian groups with special emphasis on results concerning structure problems.
E H Batho writes [2]:-
The combination in one book of treatise and textbook is not a new phenomena in mathematical publishing. However, rarely has it been done with such felicity and success as in Fuchs' book.
For more information about this book and detailed information about nine other books by Fuchs, see THIS LINK.

A talk he gave in 1964 on abelian groups made a big impression on Rüdiger Göbel, a young researcher at that time [16]:-
I vividly remember the first talk by László Fuchs I attended as a student in Baer's seminar at Frankfurt University in 1964, which took place in the physics lecture hall, where László Fuchs explained consequences of the existence of basic subgroups of abelian groups. Although abelian group theory was not my major topic at that time, in contrast to other speakers, Fuchs left a permanent impression.
Fuchs published another very successful book in 1963, namely Partially ordered algebraic systems. He held a number of visiting positions in the 1960s: Tulane University, New Orleans, USA (1961-62); the University of New South Wales, Kensington, Australia (1965); and Queen's University, Kingston, Ontario, Canada (1966). In addition to his work at the Eötvös Loránd University, Fuchs played a roles in Hungarian mathematics both in the János Bolyai Mathematical Society and in the Hungarian Academy of Sciences. He served the János Bolyai Mathematical Society as treasurer from 1949 to 1963 and then as secretary general from 1963 to 1966. He served the Hungarian Academy of Sciences by heading the Department of Algebra in its Mathematical Institute from 1963 to 1966.

In 1966 Fuchs left Hungary and emigrated to the United States. It seems that political attitudes in Hungary made his life increasingly difficult during the 1960s. He was appointed as a professor at the University of Miami, Coral Gables, Florida. On 22-23 March 1968 the Florida Section of the Mathematical Association of America was held on the South Campus of Miami-Dade Junior College, Miami, Florida. An invited address was given on Friday, 22 March by Fuchs. His subject was "On the Factorization of Abelian Groups." Later in 1968 Fuchs was appointed as a professor at Tulane University, New Orleans. He would continue to hold this position until he retired in July 2004.

In New Orleans, Fuchs met Shulamith Yakar, known as Shula. She had been born in Tel Aviv in August 1936 and lived in Gaza until the Arab Uprising. After initial training in Israel she came to the United States and was on a trip to New Orleans to visit her uncle when she met Fuchs. They were married and in 1976 Shula received BS in Pharmacy from Xavier University. They had two children, Terry Yakar Fuchs (born about 1976) and David Yakar Fuchs (born about 1978). Shula worked at the Lakeshore Hebrew Day School, and was a dedicated volunteer at Congregation Beth Israel. She accompanied her husband on many of his research visits and conferences.

Luigi Salce spent a year working with Fuchs at Tulane beginning in 1975. He writes [34]:-
Of that year spent in New Orleans in the student Rosen House, where we had a small two-room flat as accommodation, and at Gibson Hall, a beautiful neo-Gothic building where Tulane University's mathematics department was located, Paola [Salce's wife] and I have the vivid memory of a happy time. ... László taught a course on Abelian groups to PhD students, whose notes I still keep, filling several notepads. In that course I learnt the main results on totally projective groups, which made me passionate about the theory of Abelian p-groups. I then became interested in and studied for many months the existing literature on this theory, hitherto almost completely unknown to me. One evening we were invited to dinner at László's house on Laudun Street, where we got to know Shula, who was pregnant with Terry. Paola and I certainly did not think on that occasion that we would become close friends with Shula and László, as in fact happened a few years later. Thanks to László's great willingness to help, we tackled together, with him leading and me following, some problems on Abelian groups, so that by the end of the year spent at Tulane I had three published papers with László as co-author.
At Tulane University, Fuchs was named W R Irby Professor in 1979 and named Evelyn and John G Phillips Distinguished Professor in 1992. He was Chairman of the Mathematics Department at Tulane University (1977-79). Mathematical activities outside Tulane University included being Vice President of the Florida Section of the Mathematical Association of America (1967-69).

In 1970 Fuchs published the first volume of Infinite Groups, the second volume being published three years later. Elbert Walker writes [36]:-
Volumes I and II represent a truly masterful scholarly achievement, and will certainly be both the standard references and standard texts in the subject for years to come.
For details of these two volumes and further extracts from reviews, see THIS LINK.

Let us quote from Bruce Olberding and Kulumani M Rangaswamy's paper [29]:-
Professor László Fuchs is an outstanding researcher and author. His extraordinary productivity and influential monographs in the areas of abelian groups, ordered algebraic structures, rings, and modules, have directly impacted the growth and direction of research of these important areas of algebra.
...
László started his research career by diving deep into the ideal theory of rings, beginning with his thesis in commutative ideal theory. This was written without a thesis supervisor; indeed, he was the only algebraist in Budapest at the time. His work in this area remained a primary focus for the first decade of his career, and within seven years of submitting this thesis, he had earned the Kossuth Prize, the highest national award for scientists in Hungary, and he was promoted to full professor. All of this was largely based on his "first" career, that of a commutative ring theorist. Recently, after impressive and far-ranging detours into abelian groups, ordered algebraic systems and module theory, he has turned his attention back to the ideal theory of commutative rings, thus completing a full circle of his amazing journey through several important areas of research.
We note that, as of 2025, MathSciNet lists 276 research publications by Fuchs which involve 60 co-authors. These have been cited 4193 times by 2093 different authors. One of Fuchs' co-authors was Luigi Salce who wrote the papers [34] and [35] which relate many memories of the time they spent together. Let us quote from [35] Salce's personal experience as Fuchs' co-author:-
I was very happy when László asked me to collaborate with him on the first book on modules over valuation domains. But I was more proud and conscious of the task proposed to me to write our second book on modules over non-Noetherian domains. It soon seemed to be a really hard job, but the experience of László, our close friendship and his strong resolution removed my doubts. In both these experiences I admired the qualities of an outstanding mathematician and of a generous man. László has an extraordinary capacity for assimilating and elaborating large and complex portions of mathematics, for simplifying proofs and for finding new perspectives on old results. Other impressive qualities are his obstinacy in pursuing a result through a full immersion in the problem, and his capacity for identifying the good veins in the great mine of mathematics.
Fuchs retired in July 2004 and continued to live in Metairie, part of the New Orleans metropolitan area, with his wife Shula. In August 2005 the powerful devastating Hurricane Katrina caused widespread damage and flooding which shattered the lives of many in the area including Fuchs and his wife. Metairie is home to some 40 percent of the New Orleans Jewish community and in January 2006 a group of Jews came to help those struggling to recover from the devastation [26]:-
Interviewed in his trash-strewn front yard, Fuchs said he couldn't believe how in one day, this group of Jews did more to help him and his wife than anyone has done in the four months since Katrina shattered their lives. "I'm not really accustomed to asking for help, so it's very difficult to find words to express how we feel about complete strangers coming to help us," he said. Added Shula, "It's beyond words. It's overwhelming. This is our people. It makes us believe."
Eventually Shula's health began to deteriorate and Fuchs and his wife moved to Atlanta in order to be closer to family members. Shula died in the early morning of Sunday 9 April 2023 in Atlanta.

Several conferences have been organised to celebrate Fuchs' birthdays. The first was to celebrate his 60th birthday, two conferences were dedicated to him on the occasion of his 70th birthday, and another on his 75th. In 2004 Fuchs was one of the "Big Five at 80" a celebration organised by the Hungarian Academy of Sciences. There was a celebration of his 90th birthday in 2014 and in 2024 the Hungarian Academy of Sciences organised the "Big Five 100". At the Big Five 100 conference Fuchs was personally welcomed and received the János Arany Lifetime Achievement Award, the most prestigious academic honour for Hungarian scientists abroad, from the President of the Hungarian Academy of Sciences. Fuchs then gave an address, summarised in [5]:-
Looking back over his mathematical career, Fuchs explained how his path led him from primal ideals theory, through the theory of ordered algebraic structures, to the study of Abelian groups and unsolved problems.

"This has remained my favourite subject all my life; I have written three books on Abelian groups," he continued. "Perhaps I made a mistake by changing my research problems frequently, but I confess I couldn't resist trying to solve an interesting problem that arose. I was eighty years old when I retired, but there was no way I could stop doing mathematics. During the last twenty years I have written about many old problems and clarified many interesting questions in a new field for me, the new branch of commutative rings. I am happy to say that I have managed to prove an important existential theorem. The theorem: mathematics still exists after ninety years. This is not a new theorem, but we can agree that it is not easy to prove. It is a common practice to make promises of future work at the occasion of recognition. At my age, this makes no sense. But I can safely say that my award confirms my ambition to prove that mathematics still exists after a hundred years."
After Fuchs made his speech, he was awarded the platinum diploma of Eötvös Loránd University's Faculty of Science [5]:-
... in recognition of an outstanding life's work and also in memory of his service as Dean of the Faculty of Mathematics, Physics and Chemistry at Eötvös Loránd University between 1954 and 1956.
