About Rodney Dangerfield:
Rodney Dangerfield (November 22, 1921 – October 5, 2004), born Jacob Cohen, was an American comedian, and actor, known for the catchphrases "I don't get no respect" or "I get no respect, I tell ya" and his monologues on that theme. He is also famous for his 1980s film roles, notably in Easy Money, Caddyshack and Back To School.
Early career
In the early 1960s he started down what would be a long road toward rehabilitating his career, still working as a salesman by day. He came to realize that what he lacked was an "image"—a well-defined on-stage persona that audiences could relate to and that would distinguish him from similar comics.
He took the name Rodney Dangerfield, which had been used as the comical name of a faux cowboy star by Jack Benny on his radio program at least as early as the December 21, 1941, broadcast and later as a pseudonym by Ricky Nelson on the TV program The Adventures of Ozzie and Harriet. However, Jack Roy remained his legal name, as he mentioned from time to time.[6] During a question-and-answer session with the audience on the album No Respect, Rodney joked that his real name was Percival Sweetwater.
