Stefan Emanuel "Steve" Warschawski (April 18, 1904 – May 5, 1989) was a Russian-born American mathematician, a professor and department chair at the University of Minnesota and the founder of the mathematics department at the University of California, San Diego.
[1] After receiving his Ph.D., Warschawski took a position at Göttingen in 1930 but, due to the rise of Hitler and his own Jewish ancestry, he soon moved to Utrecht University in Utrecht, Netherlands and then Columbia University in New York City.
[1][3] The Noshiro–Warschawski theorem is named after Warschawski and Noshiro, who discovered it independently;[9][10][11][12] it states that, if f is an analytic function on the open unit disk such that the real part of its first derivative is positive, then f is one-to-one.
[3] The Stephen E. Warschawski Memorial Scholarship was also given in his name in 1999–2000 to four UCSD undergraduates as a one-time award.
[7] His wife, Ilse, died in 2009 and left a US$1 million bequest to UCSD, part of which went towards endowing a professorship in the mathematics department.
