She was married to the mathematician Isaac (Iso) Jakob Schoenberg. Af teer studying at the universities of Jassy (Iasi) in Moldavia, and Ber ling, Schoenberg studied in Gottingen where he met Georg Landau. In 1 928 Landau arranged for Schoenberg to go to the Hebrew University in J erusalem. When he returned in 1930 he married Landau's daughter Charl otted.

About Isaac (Iso) Jakob Schoenberg from the website Wikipedia:
Schoenberg was born in Galai. He studied at the University of Iai, r eceiving his M.A. in 1922. From 1922 to 1925 he studied at the Univers ities of Berlin and Göttingen, working on a topic in analytic number t heory suggested by Issai Schur. He presented his thesis to the Univers ity of IaÈ™i, obtaining his Ph.D. in 1926. In Göttingen, he met Edmun d Landau, who arranged a visit for Schoenberg to the Hebrew Universit y of Jerusalem in 1928. During this visit, Schoenberg began his influe ntial work on total positivity and variation-diminishing linear transf ormations. In 1930, he returned from Jerusalem, and married Landau's d aughter Charlotte in Berlin.

In 1930, he was awarded a Rockefeller Fellowship, which enabled him t o go to the United States, visiting the University of Chicago, Harvard , and the Institute for Advanced Study in Princeton, New Jersey.

Penn. in order to perform war wor k as a mathematician at the Aberdeen Proving Ground. It was during thi s time that he initiated the work for which he is most famous, the the ory of splines.

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

His books:
Schoenberg, I. J. (1973), Cardinal Spline Interpolation, Society for I ndustrial and Applied Mathematics[2]
Schoenberg, I. J. (1982), Mathematical time exposures, Mathematical As sociation of America, ISBN 0-88385-438-4, Unknown ID:loc=82-062766
Schoenberg, I. J. (1988), Selected Papers, Vol.1 and 2 (Ed. C. de Boor ), Birkhäuser.

He wrote about 175 papers on many disparate subjects. Around 50 of the se were on Splines. He also wrote on Approximation theory, the Kakey a problem, Polya frequency functions, and a problem of Edmund Landau . His coauthors included John von Neumann, Hans Rademacher, Theodore M otzkin, George Polya, A. S. Besicovitch, Gabor Szego, Donald J. Newman , Richard Askey, Bernard Epstein, and Carl de Boor.
