Funnyman Sid Caesar dead at 91

(CNN) -- 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, does not know the exact cause of death, but says 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.
