Isaac Sidney "Sid" Caesar (September 8, 1922 – February 12, 2014) was an American comic actor and writer, best known for the pioneering 1950s live television series Your Show of Shows, a 90-minute weekly show watched by 60 million people, and its successor Caesar's Hour, both of which influenced later generations of comedians. He also acted in movies; he played Coach Calhoun in Grease (1978) and its sequel Grease 2 (1982), and appeared in the films It's a Mad, Mad, Mad, Mad World (1963), Silent Movie (1976), History of the World, Part I (1981), and Cannonball Run II (1984).Caesar was considered a "sketch comic" and actor, as opposed to a stand-up comedian. He was also a saxophonist and author of several books, including two autobiographies in which he described his career and later struggle to overcome years of alcoholism and addiction to barbiturates.
