When Caesar Was King: How Sid Caesar Reinvented American Comedy

by David Margolick

LONGLISTED FOR THE PEN/JACQUELINE BOGRAD WELD AWARD FOR BIOGRAPHY • From longtime New York Times and Vanity Fair writer David Margolick comes the first definitive biography of Sid founding father of television comedy and icon to generations of Americans.

“Whip smart. . . . A nuanced appreciation of Caesar’s comedy and the overall atmosphere of TV’s early days.” —Esquire

By the spring of 1954, Sid Caesar was the most influential, highly paid, and enigmatic comedian in America. Every week, twenty million people tuned their TVs to his NBC extravaganza, Your Show of Shows, and witnessed his virtuosity in sketches and film spoofs, pantomime and soliloquy. Onstage, Caesar could play any character and make it a befuddled game-show contestant, a pretentious German professor, a beleaguered husband (opposite his redoubtable co-star Imogene Coca)—even a gumball machine and a bottle of seltzer.

To Caesar’s mostly urban audience, his comedy was an era-defining leap forward from the days of vaudeville, launching a new style of humor that was multilayered and full of character, yet still uproarious. To his rivals, Caesar was the man to beat. To his fellow American Jews, his show’s success meant something a post-Holocaust symbol of security and a source of great pride. But behind all that Caesar represented was the real Sid. Introverted and volatile, ill at ease in his own skin, he could terrorize his collaborators but reserved his harshest critiques for himself. After barely a decade, he was essentially off the air, beset by exhaustion, addiction, his own impossibly high standards, and changing viewership as television spread to the American heartland. TV’s first true comic creation was also its first spectacular flameout.

But in his wake came the disciples he personally nurtured—including Mel Brooks, Carl Reiner, Neil Simon, and more. Caesar left an indelible impact on what still makes us laugh. In When Caesar Was King, veteran journalist David Margolick conjures this complexman as never before. Deeply researched, brimming with love for Caesar and the culture from which he sprang, and reanimating a New York City that has all but vanished, this rollicking and poignant book traces the rise and fall of a legend.

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.

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.

[Mark Selby · Rating 3 out of 5]

I loved the incredible amount of detail on this golden era of TV comedy, but it’s baffling to me how the author perpetually relies on negativity; if you didn’t already know how large Sid Caesar looms in TV’s formative years — literally and figuratively — you’d never get the sense from this book, in which, if the repetitious text is to be believed, the shows were only rarely funny, the ratings constantly slipping, and the reviews consistently negative or tepid at best, with the audience turning on Sid almost from the get-go. I’m grateful this isn’t a hagiography but there almost seems to be a lack of affection from the author. He also left out Sid’s attempts to syndicate his shows in the 1980s and the revival he enjoyed even later in life when several compilation volumes were released on home video. It’s a good book about early TV comedy and thoroughly researched, but it’s confusing to claim Caesar was king of comedy and then spend 300 pages of writing claiming that, in fact, few seemed to really enjoy him.

I’m a bit too young—believe it or not—to have actually experienced Sid Caesar in his prime on television, in the beginning years of that medium. But I’ve always been curious about him, even though the few bits and pieces I have seen of Your Show of Shows and Caesar’s Hour have been not exactly my cup of tea. He was certainly the toast of the town at one point when it came to his weekly variety and sketch shows, but then … what happened? Caesar was TV’s biggest and most critically lauded star in the early to mid 1950s, and then, POOF!—he was pretty much gone. David Margolick’s book traces Caesar’s rise and fall and paints a picture of what early network television was like. In Caesar’s wake, he gave us people like Mel Brooks, Carl Reiner, Larry Gelbart, Neil Simon, and even a little bit of Woody Allen. The book bogs down a bit with lengthy descriptions of skits and Caesar’s therapy history, but it's still a fascinating look at an era when everything was brand new, including the concept of a comedy/variety show and the people who became stars doing it.

Audio. I knew very little about Sid outside of a few old videos and lots of references. This was a very enjoyable biography that really got down into the nuts and bolts of his life and career. A truly amazing performer. This book inspired me to look up a bunch of his old sketches on YouTube. He was a very forceful and animated performer. It was interesting to find out how involved and close Mel Brooks was to him. It was illuminating to read about the early days of TV with all the early innovators and how comedy evolved.

[Bob K · Rating 4 out of 5]

A thorough account of the life of this important entertainment figure. I was born years after his TV dominance and I was aware of his importance, but the popularity and this book is good at really driving home just how massive he and his programs were in the 50s. The sad part is that even though many in Caesar's orbit went on to have lengthy, storied careers (Mel Brooks, Carl Reiner), the man himself didn't have that same sustained success, although he remained wealthy. The book does a good job of diving into the demons that had something to do with that, along with his triumphs.

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.

[Ben Baker · Rating 4 out of 5]

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.
