15896 Birkhoff           Discovered 1997 June 13 by P. G. Comba at Prescott.
George David Birkhoff (1884-1944) was one of the foremost American mathematicians of the early twentieth century. He made important contributions to ergodic theory, the topological theory of dynamical systems, ordinary differential equations and difference equations.
