George David Birkhoff (March   21, 1884 – November   12, 1944) was one of the top American mathematicians of his generation. He made valuable contributions to the theory of differential equations , dynamical systems , the four-color problem , the three-body problem , and general relativity . Today, Birkhoff is best remembered for the ergodic theorem . The George D. Birkhoff House , his residence in Cambridge, Massachusetts , has been designated a National Historic Landmark .

His 1943 theory of gravitation is also puzzling since Birkhoff knew (but didn't seem to mind) that his theory allows as sources only matter which is a perfect fluid in which the speed of sound must equal the speed of light . Birkhoff believed that fellowships from foreign nations would improve the mathematic standards in the United States, though he wanted to raise

Gian-Carlo Rota writes: "Like other persons rumored to be anti-Semitic, he would occasionally feel the urge to shower his protective instincts on some good-looking young Jew. Ulam's sparkling manners were diametrically opposite to Birkhoff's hard-working, aggressive, touchy personality. Birkhoff tried to keep Ulam at Harvard, but his colleagues balked at

In 1913, he proved Poincaré's " Last Geometric Theorem ,"

Summarizing Birkhoff's selection process, fellow mathematician Oswald Veblen would write: While Birkhoff was subject to as many prejudices as most of us, he kept always what most of us lose as we grow older, the power to see people and events simply and naively rather than with reference to current opinion.
