Emil Grosswald (December 15, 1912 – April 11, 1989) was a mathematician who worked primarily in number theory. His doctoral advisor was Hans Rademacher.

Life and education[edit]

Grosswald was born on December 15, 1912 in Bucharest, Romania. He received a Master's degree in both mathematics and electrical engineering from the University of Bucharest in 1933, spent 6 months in Italy and then received a a Diplôme de l”Ecole de l’Electricité de Paris.[1]

Grosswald was Jewish. When war broke out, he fled from Paris in June, 1940 to Montpellier, where he began doctoral studies in mathematics. He fled at the end of 1941, through Spain and Lisbon to Cuba. He moved to Puerto Rico in 1946 and then to the United States in 1948. He received his PhD under Hans Rademacher from the University of Pennsylvania in 1950.[2] He was Visiting Professor at the University of Paris in 1964-1965 and his book, The Theory of Numbers was written that year.

He met his wife Elisabeth (Lissy) Rosenthal in Cuba, probably in 1941 or 1942. They were married in 1950 in Saskatoon, Canada, where he had his first teaching position after receiving his Ph.D. They spent two years at the Institute for Advanced Studies in Princeton, in 1951 and 1959. During their first stay, they met Einstein, with whom Emil had a correspondence, later bequeathed to the University of Texas, and formed many friendships, among others with the physicist Freeman Dyson. Emil and Lissy had two daughters, Blanche, who became a professor of Social Work at Rutgers University but died in 2003 at the age of 50, and Vivan, a professor of law at the University of Pittsburgh. Vivian was decorated in 2007 by the Republic of Austria for her work as the United States appointee to the Austrian General Settlement Fund Committee for Nazi-era property compensation, and in 2013 by the government of France for her services in promotion of the French language and culture in the United States. Emil is the uncle of Pamela Ronald, whose father Robert Ronald (né Rosenthal) describes the family’s escape from the Nazis in his memoir Last Train to Freedom. The son of Lissy’s second cousin (Ernest Beutler) is 2011 Nobel Laureate Bruce Beutler. Emil was also the nephew of the French musician Marcel Mihalovici, who arrived in Paris in the 1920s with Enesco.

Grosswald died April 11, 1989 in Narberth, Pennsylvania.[1]

Career[edit]

Grosswald's first three scientific papers, written while he was in Cuba, were published under the pseudonym E. G. Garnea.[3]:11 He published articles in English, German, French, Spanish and Italian.

After receiving his PhD in 1950, Grosswald taught at the University of Pennsylvania from 1952 to 1968 and then moved to Temple University and stayed until his retirement in 1980. He also held positions at the University of Saskatchewan (1950), Institute for Advanced Study (1951 and 1959), the Technion (1980–1981), Swarthmore College (1982), and the University of Pennsylvania (1984).[1]

Grosswald completed some works of his teacher Hans Rademacher, who died in 1969. Rademacher had prepared notes for an Earle Raymond Hedrick Lecture in Boulder, Colorado in 1963 on Dedekind sums, but fell ill, and Grosswald gave the lecture for him.[4] After Rademacher's death, Grosswald edited and completed the notes and published them in the Carus Mathematical Monographs series as Dedekind Sums.[5]:214 He also edited for publication Rademacher's posthumous textbook Topics in Analytic Number Theory.[1]

Grosswald was elected to the Board of Governors of the Mathematical Association of America for 1965–1968.[6] Temple University's Mathematics Department annually sponsors the Emil Grosswald Memorial Lectures.[7]
