30444 Shemp           Discovered 2000 July 5 by J. Broughton at Reedy Creek Observatory.
Brooklyn-born Shemp Howard (Samuel Horwitz, 1895-1955) of Three Stooges fame was an original member during their 1920s vaudeville years. In 1946 he appeared on screen to replace his ailing brother Curly. Like Curly, Shemp was a naturally gifted comedian who brought his own style of comedy to the act.
