The George David Birkhoff Prize in applied mathematics is awarded jointly by the American Mathematical Society (AMS) and the Society for Industrial and Applied Mathematics (SIAM) in honor of George David Birkhoff (1884–1944). It is currently awarded every three years for an outstanding contribution to "applied mathematics in the highest and broadest sense."[1][2] The recipient of the prize has to be a member of one of the awarding societies, as well as a resident of the United States of America, Canada, or Mexico. The prize was endowed in 1967, first issued in 1968, and currently (2020) amounts to US$5,000.
