When Sid Caesar Redefined American Comedy

Sid Caesar’s reign in television was brief. But from 1949 to 1960 or so, he helped define what made America laugh. And thanks to his many, many disciples, his influence extended into, and remains in, every corner of comedy.

Caesar was among TV’s first and most magnificent comic creations, someone who, rather than recycling vaudevillian wisecracks and nightclub shtick, fashioned a more intimate and cerebral brand of humor.

Tuning in weekly on their primitive DuMonts and Zeniths — first on The Admiral Broadway Revue, then on the legendary Your Show of Shows and finally on the largely (and unfairly) forgotten Caesar’s Hour — viewers saw the full range of Caesar’s extraordinary gifts for sketch comedy, soliloquy and pantomime, and enjoyed his fluency in “pidgin” French, Italian, German, Japanese and Arabic.

His was a new kind of comedy: thoughtful, insightful, built around human nature rather than the silly or ephemeral. And viewers got a sense of the humanity of Caesar himself — forever sweating, stammering and coughing before their eyes and ears — that only live television could provide.

Working alongside him were some of the greatest comic talents of the era: not only his costars Carl Reiner, Imogene Coca (and, later, Nanette Fabray) and Howard Morris but also his writers, waging war with one another in his legendary writers’ rooms. It was Caesar who discovered, then coddled and mentored, the young Mel Brooks. Joining him through the years were Neil Simon, Mel Tolkin, Joe Stein, Larry Gelbart and Woody Allen, among others.

Then there were all those who studied, and learned from, Caesar. Johnny Carson ripped off his routines for student shows at the University of Nebraska, while Dick Cavett played hooky from Yale to go to New York and watch him perform. Carol Burnett modeled her show after his. So, too, after a fashion, did Saturday Night Live, which, paying homage to him, had Caesar guest-host a show in 1983.

Ten-year-old Conan O’Brien and, before him, 6-year-old Billy Crystal vowed to become comedians after seeing Caesar’s landmark takeoff of the 1950s show This Is Your Life.
