Curly Howard: Jerome Lester Horwitz (October 22, 1903 – January 18, 1952), better known by his stage name Curly Howard, was an American comedian and vaudevillian actor.  He was best known as a member of the American farce comedy team the Three Stooges, which also featured his older brothers Moe and Shemp Howard and actor Larry Fine.  Curly 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 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).
