Louis A. Phelan (March, 1864 – November 2, 1933) was a manager in Major League Baseball in the 1895 season, with the St. Louis Browns. A saloon-keeper, Phelan was hired on the basis that owner Chris von der Ahe was seeing a mistress that happened to be sister of Phelan's wife.[1] During his lone season as manager, he led the Browns to 11 wins, with 30 losses in 45 games. After managing in those 45 games in 1895, he was replaced by Harry Diddlebock.
