When Caesar Was King: How Sid Caesar Reinvented American Comedy

by David Margolick

From longtime Vanity Fair contributing editor David Margolick comes the first definitive biography of Sid founding father of American comedy and the icon who made modern television.

In the spring of 1954, Sid Caesar was America’s number one mensch. Each Saturday night, the 31-year-old sketch comic from Yonkers performed for a crowd of twenty million—some crammed into Manhattan’s cavernous Center Theater, but most plopped on their couches, where Caesar beamed back at them through some of the first TVs to light up living rooms.

For many Americans, Caesar was television. And Your Show of Shows, the 90-minute variety program that catapulted him to stardom, was his magnum opus. Onstage, Caesar could be a befuddled suburban husband, a pretentious expert fibbing through an interview, a gumball machine, a bottle of seltzer. And he could make anything funny. But behind the entertainer was the introverted and tongue-tied, an actor whose hardest role was to simply be himself. Few could have known that, within just a few years, Caesar would be off the air. Television’s first true star was also its first fall from grace. But in his wake would come the talents he personally nurtured―including Mel Brooks, Carl Reiner, and Neil Simon―and the generations of comedians he inspired.

In When Caesar Was King, veteran journalist David Margolick conjures Caesar like few writers can. Deeply researched and brimming with love for its subject, this rollicking and affecting book charts the meteoric rise and fall of a true legend, and his lasting impact on what makes us all laugh.

I’ve known that Sid Caesar was one of the giants of 50’s television, but I really haven’t seen much of Your Show of Shows because it really wasn’t something that was rerun over the years. I learned a lot of things I didn’t know from this book-including Sid’s show was basically booted off the air by a rival show…Lawrence Welk? Really??

I also checked out a couple of clips of Your Show of Shows on YouTube. If you only look at one, I suggest you check out the This is Your Life spoof.

Book highly recommended for TV history fans.

Epitome of Biography

Definitive Biography of a genius. Long overdue. The only thing that could improve it is the availability of its subject.

Wow. In-depth, fascinating, funny, heartbreaking, and ultimately a beautiful account of a complicated comic trailblazer.

[Glenn R. Miller · Rating 5 out of 5]

Excellent, balanced bio on a funny, flawed man. Margolick helps provide context on the importance of Sid Caesar within the rise of television during the early '50s. As a kid of the '60s, I couldn't help but feel I had missed tv's first golden age. This book is a wonderful return to that time.

[Seth Petok · Rating 5 out of 5]

Murderers row of writers - Neil Simon, Larry Gelbhart, Woody Allen, Carl Reiner - launch Caesar to define television comedy in the 1950s golden age. These writers zigged, while Sid zagged the rest of his career. Sid’s shows were, witty, sophisticated, cutting satire and intelligent satire an antecedent of SNL. Wonderfully researched and written.

Started reading this on a hunch and I’m glad I did. Knew Caesar was a comic legend but nothing else. This book did a good job painting the picture of the man.

I listened to the audiobook. I was hoping to hear some of his actual routines, instead the narrator read them. Still funny. I now know more about Caesar than I wanted to know, but still a worthwhile listen.

[Susan Rainwater · Rating 2 out of 5]

I think I took away the wrong message from this book. I certainly did not get "king of comedy". Rather, Caesar seems like a one-hit wonder who was very much of his time, and was never able to recapture his glory days.

I wanted to know more about the comedy than the person but the tale is well told. Shame his last fifty years or so are practically on fast forward.
