Moses Fleetwood Walker (born 1856) was an American sportsman, author and inventor. Walker succeeded in baseball: he is credited by some with being the first African-American to be in the Major League Baseball. Moses was a catcher of the Toledo Blue Stockings club for one season. Until 1889 he was playing in minor leagues. Then the color limit was set in professional baseball, so Moses Fleetwood Walker was prevented from playing in a major league.

After leaving baseball in 1891, Walker became a businessman and an inventor. He ran a hotel and a theater, published a newspaper and even patented several inventions. He cared much about the future of African-Americans, supported black nationalism and led an active political life. He died on the 11th of May, 1924.
