Emil Grosswald (December 15, 1912 – April 11, 1989) was a mathematician who worked primarily in number theory. Life and education 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 six months in Italy and then received a Diplôme from École supérieure d'électricité in Paris. Grosswald was Jewish. When war broke out, he fled from Paris in June, 1940 to the University of 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 Ph.D. under Hans Rademacher from the University of Pennsylvania in 1950. He was Visiting Professor at the University of Paris in 1964–1965 and one of his books, 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 Study in Princeton, New Jersey in 1951 and 1959. During their first stay, they met Albert 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 Vivian, 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, a member of the National Academy of Sciences, 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 composer Marcel Mihalovici, who arrived in Paris in the 1920s with Georges Enesco. After
