The Three Stooges Biography (Wikipedia)
The Three Stooges were an American vaudeville and comedy team active from 1922 until 1970, best known for their 190 short subject films by Columbia Pictures that have been regularly airing on television since 1958. Their hallmark was physical farce and slapstick. Six stooges appeared over the act's run (with only three active at any given time): Moe Howard and Larry Fine were mainstays throughout the ensemble's nearly fifty-year run and the pivotal "third Stooge" was played by (in order of appearance) Shemp Howard, Curly Howard, Shemp Howard again, Joe Besser, and Curly Joe DeRita.
The act began in the early 1920s as part of a vaudeville comedy act billed as "Ted Healy and His Stooges", consisting originally of Healy and Moe Howard. Over time, they were joined by Moe's brother Shemp Howard, and then Larry Fine. The four appeared in one feature film, Soup to Nuts, before Shemp left to pursue a solo career. He was replaced by his younger brother, Jerome "Curly" Howard, in 1932. Two years later, after appearing in several movies, the trio left Healy and signed on to appear in their own short-subject comedies for Columbia Pictures, now billed as "The Three Stooges". From 1934 to 1946, Moe, Larry and Curly produced over 90 short films for Columbia. It was during this period that the three were at their peak popularity.
