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 .
