About Isaac (Iso) Jakob Schoenberg from the website Wikipedia:
Schoenberg was born in Galai. He studied at the University of Iai, receiving his M.A. in 1922. From 1922 to 1925 he studied at the Universities of Berlin and Göttingen, working on a topic in analytic number theory suggested by Issai Schur. He pr esented his thesis to the University of IaÈ™i, obtaining his Ph.D. in 1926. In Göttingen, he met Edmund Landau, who arranged a visit for Schoenberg to the Hebrew University of Jerusalem in 1928. During this visit, Schoenberg began his influential w ork on total positivity and variation-diminishing linear transformations. In 1930, he returned from Jerusalem, and married Landau's daughter Charlotte in Berlin.

In 1966 he moved to the University of Wisconsin-Madison where he became a member of the Mathematics Research Center. He remained there until he retired in 1973. In 1974 he won a Lester R. Ford Award.
