“Spirited and revealing. . . . An astute psychological profile of the man whose biting, nihilistic comedy broke so many barriers.”—John McMurtrie, San Francisco Chronicle

"Trenchant and provocative."—Dennis Drabelle, Washington Post

"There is no doubt that the author loves the 13 films the brothers made together, but his fascination lies with those moments when they go too far, toppling toward Samuel Beckett's "mirthless laugh," which laughs "at that which is unhappy"… [The book] is full of sensitive observations about Harpo's musical vocation and Groucho's uncanny greasepaint, details to propel readers back to the films… You suspect Marx, frustrated doctor and unlikely pen pal of T.S. Eliot, would have appreciated being taken so seriously."—Victoria Segal, Sunday Times

"A luminous delight . . . A true page-turner and a lot of fun. [Siegel]  applies his own philosophical acuity to the personal and socio-political aspects of Groucho’s life."—Shon Arieh-Lerer, Slate

"A scholarly milestone in the history of professional writing on Groucho Marx."—Cineaste

“Was [Groucho] serious or funny? Where did the persona stop and the real Groucho begin? Lee Seigel wrestles with these questions in his provocative and short critical biography of the man he calls the Marx Brothers’s “central intelligence”.”—Karl Whitney, The Guardian

"Delightfully perverse." —New York Times Book Review

"A contentious but always stimulating addition to the surprisingly small library of Marx Bros studies."—Jewish Chronicle

"As Lee Siegel’s Groucho Marx: The Comedy of Existence, a book in Yale University Press’s Jewish Lives series, makes plain, Groucho was a man who could find a cloud in every silver lining."—Jewish Review of Books

“[A] forensic and well-informed analysis of the brother’s comedy through their lives . . . Siegel is good at building on finds from his extensive sources to create vivid pictures – and plausible assumptions . . . There are plenty of unusual insights."—Jewish Renaissance

“A beautiful, brilliant, and persuasive reading of Marx as crypto-nihilist. A necessary and pulse-quickening work (utterly bereft of jargon or self-seriousness), linking Aristophanes to Kafka to Beckett to Groucho to Woody Allen to Amy Schumer.”—David Shields, author of Reality Hunger

“Lee Siegel’s brilliant analysis of the glorious, scary, beyond-funny humor of Groucho and his brothers made me feel as if I were watching their movies for the first time. In this hugely enjoyable and stimulating book, Siegel shows how Groucho became an impossibility: an immortal comedian.”—Ian Frazier, author of Great Plains and On the Rez
