Mordecai Brown, American baseball player, coach, and manager (d. 1945)
Mordecai Peter Centennial Brown (October 19, 1876 – February 14, 1948), nicknamed Three Finger Brown or Miner, was an American Major League Baseball pitcher and manager during the first two decades of the 20th century (known as the "dead-ball era"). Due to a farm-machinery accident in his youth (April 17, 1888), Brown lost parts of two fingers on his right hand, and in the process gained a colorful nickname. He turned this handicap into an advantage by learning how to grip a baseball in a way that resulted in an exceptional curveball (or knuckle curve), which broke radically before reaching the plate. With this technique he became one of the elite pitchers of his era.

Brown was elected to the Baseball Hall of Fame in 1949.
