Jerome Lester Horwitz (October 22, 1903 – January 18, 1952), known professionally as Curly Howard, was an American vaudevillian comedian and actor. He was best known as a member of the American farce comedy team the Three Stooges, which also featured his elder brothers Moe and Shemp Howard and actor Larry Fine. Curly Howard was generally considered the most popular and recognizable of the Stooges. He was well known for his high-pitched voice and vocal expressions ("nyuk-nyuk-nyuk!", "woob-woob-woob!", "soitenly!" [certainly], and barking like a dog), as well as his physical comedy (e.g., falling on the ground and pivoting on his shoulder as he "walked" in circular motion), improvisations, and athleticism. An untrained actor, Curly borrowed (and significantly exaggerated) the "woob woob" from "nervous" and soft-spoken comedian Hugh Herbert. Curly's unique version of "woob-woob-woob" was firmly established by the time of the Stooges' second Columbia film, Punch Drunks (1934). Howard was forced to leave the Three Stooges act in May 1946 when a massive stroke ended his show-business career. He suffered through serious health problems and several more strokes until his death in 1952 at age 48.
