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

When war broke out, he fled from Paris in June, 1940 to the University of Montpellier, where he began doctoral studies in mathematics.

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.

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 was also the nephew of the French composer Marcel Mihalovici, who arrived in Paris in the 1920s with Georges Enesco.
