Max Shiffman
- Max Shiffman** (30 October 1914, New York City – 2 July 2000, Hayward, California) was an American mathematician, specializing in the calculus of variations, partial differential equations, and hydrodynamics. He was a Guggenheim Fellow for the academic year 1951–1952.
Biography Max Shiffman graduated with a bachelor's degree from City College of New York (CNNY) and his thesis advisor was Richard Courant. According to Peter Lax, Shiffman was "Courant's most brilliant student in America". Shiffman gave a one-hour address at a meeting of the American Mathematical Society. He was an instructor at CCNY in 1939–42. In 1942 at NYU he joined a research project funded by the Office of Scientific Research and Development. From 1945 to 1948 he was an associate professor at NYU, where he influenced many graduate students, including Clifford Gardner, Joe Keller, Martin Kruskal, Peter Lax, Cathleen Morawetz, and Louis Nirenberg. In 1948 Gábor Szegő hired Shiffman as a full professor at Stanford University. Shiffman and Bellman introduced a number of modern mathematics courses at Stanford. Shiffman was the first to teach at Stanford a course on functional analysis. is due to Shiffman in 1949.
{{blockquote|His brilliant career came to a tragic halt in 1951, due to a schizophrenic breakdown. He recovered and continued his research and teaching until a second breakdown in 1956. With the support of his friends and a generous trustee of Stanford University, he was admitted to Chestnut Lodge, a prestigious psychiatric institute. After nine years of therapy he was transferred to Agnews State Hospital in California, where Max took advantage of a state law and sued in court to be released; he convinced a jury that he was mentally competent. with a generalization to concave-convex functions. Maurice Sion generalized Shiffman's result to Sion's minimax theorem, published in 1958.
In 1938 Bella Manel, a mathematics graduate student at NYU, married Max Shiffman. She received her PhD in 1939 with thesis advisor Richard Courant. Max and Bella Shiffman divorced in 1957, after the birth of their two sons. Upon his death Max Shiffman was survived by his sons, Bernard, a professor of mathematics, and David, an owner of an investment company, and by five grandchildren.
