Life

Wolfe received his bachelor's degree, masters, and Ph.D. degrees from the University of California, Berkeley.^[2] He and his wife, Hallie, lived in Ossining, New York.^[1]

Career

In 1954, he was offered an instructorship at Princeton, where he worked on generalizations of linear programming, such as quadratic programming and general non-linear programming, leading to the Frank–Wolfe algorithm^[3] in joint work with Marguerite Frank, then a visitor at Princeton. When Maurice Sion was on sabbatical at the Institute for Advanced Study, Sion and Wolfe published in 1957 an example of a zero-sum game without a minimax value.^[4] Wolfe joined RAND corporation in 1957, where he worked with George Dantzig, resulting in the now well known Dantzig–Wolfe decomposition method.^[5] In 1965, he moved to IBM's Thomas J. Watson Research Center in Yorktown Heights, New York.

Honors and awards

He received the John von Neumann Theory Prize in 1992, jointly with Alan Hoffman.
