Sid Caesar, a pioneer of TV comedy in the US who was well-known for playing Coach Calhoun in the film Grease, has died aged 91.
Family spokesman Eddy Friedfeld said Sid died at his home in the Los Angeles area after a brief illness.
"He had not been well for a while. He was getting weak," said Eddy, who wrote the 2003 biography Caesar's Hour.
Carl Reiner, who worked as a writer-performer with Sid on his breakthrough Your Show of Shows comedy programmre said he had an ability to "connect with an audience and make them roar with laughter".
"Sid Caesar set the template for everybody," Reiner told KNX-AM in Los Angeles. "He was without a doubt, inarguably, the greatest sketch comedian-monologist that television ever produced. He could ad-lib. He could do anything that was necessary to make an audience laugh."
"He was one of the truly great comedians of my time and one of the finest privileges I've had in my entire career was that I was able to work for him," Woody said in a statement.
