Sid Caesar, whose clever, anarchic comedy on such programs as "Your Show of Shows" and "Caesar's Hour" helped define the 1950s "Golden Age of Television," has died. He was 91.

A friend of the family, actor Rudy De Luca, did not know the exact cause of death, but said Caesar had respiratory problems and other health problems for several years.

Caesar became famous for "Your Show of Shows," which went on the air in 1950. It lasted four years and was followed by "Caesar's Hour," which combined sketches, musical revues and situation comedy.

Both shows featured writers who became famous in their own right, including Neil Simon, Carl Reiner, Mel Brooks, Mel Tolkin, Lucille Kallen and Larry Gelbart. Woody Allen also contributed to Caesar's comedy as a writer for one of his specials.

Brooks visited Caesar last night to say goodbye, De Luca told CNN.

"Sid Caesar was a giant-maybe the best comedian who ever practiced the trade & I was privileged to be one of his writers & one of his friends," Brooks tweeted Wednesday.

Caesar also appeared in a number of films, including "It's a Mad, Mad, Mad, Mad World" (1963), "Airport 1975" (1974) and "Grease" (1978). He received a Tony nomination for his performance in the 1962 show "Little Me," with a book by Simon.

Caesar, born Isaac Sidney Caesar in 1922, was part of a pioneering group of personalities who helped establish television in its early days. However, while comedians such as Jack Benny and Fred Allen more or less transferred their radio shows to the new medium and Milton Berle's "Texaco Star Theater" was essentially vaudeville on the small screen, Caesar's "Show of Shows" presented movie parodies, wordless pantomimes and brisk routines between the host and co-star Imogene Coca.
