Biography of David Gale

David Gale is an outstanding American mathematician and economist, as well as an honorary professor at the University of California in Berkeley. He conducts research in the fields of mathematics, economics, industrial engineering, and operations research. Gale has significantly contributed to the development of mathematical economics, game theory, and convex analysis. He obtained his degree in mathematics from Princeton University.

From 1950 to 1965, David taught at Brown University before joining the University of California. He currently resides in both Berkeley and Paris, sharing his life with his partner, Sandra Gilbert, who is renowned for her feminist studies and poetic works. David has three daughters and two grandchildren.

Among Gale's notable works, it is important to mention his proof of the existence of competitive equilibrium and his solution to the n-dimensional Ramsey problem. Alongside F.M. Stewart, Gale laid the foundation for research on infinite games with complete information, which greatly influenced the development of mathematical logic. Additionally, he is known as the inventor of several logic games, including 'Bridg-It' and 'Chomp'.

David played a significant role in the establishment of linear programming and linear inequalities theory. In 1960, he published the classic book "The Theory of Linear Economic Models," which remains one of the fundamental guides in this field. Another important contribution Gale made to optimization theory, coding, and algebraic geometry is the "Gale transform," a distinctive method for transforming sets of points in projective space.

Together with Lloyd Shapley, David conducted extensive research on the stable marriage problem. Their solution has had a profound impact on the analysis of matching markets and is actively applied in practical scenarios, such as student assignments to schools in New York and Boston. From 1991 to 1997, Gale wrote a column called "Mathematical Entertainments" for the "Mathematical Intelligencer" journal. The content of this column later formed the basis of his book "Tracking the Automatic Ant."
