Leo Durocher, American baseball player and manager (d. 1991)
Leo Ernest Durocher (French spelling Léo Ernest Durocher) (; July 27, 1905 – October 7, 1991), nicknamed Leo the Lip and Lippy, was an American professional baseball player, manager and coach. He played in Major League Baseball as an infielder. Upon his retirement, he ranked fifth all-time among managers with 2,008 career victories, second only to John McGraw in National League history. Durocher still ranks tenth in career wins by a manager. A controversial and outspoken character, Durocher had a stormy career dogged by clashes with authority, the baseball commissioner, the press, and umpires; his 95 career ejections as a manager trailed only McGraw when he retired, and still ranks fourth on the all-time list.

Durocher was posthumously elected to the Baseball Hall of Fame in 1994.
