As a Marx Brothers fan, I've purchased and read many of the biographies/critiques of Groucho and Bros. (and there are a *lot* of them!), and I found this to be one of the most entertaining. We've reached the point in history where first-hand biographies can no longer be written--most of Groucho's friends, collaborators, and family are dead, so Kanfer's is likely the first of books that will study Groucho from a more historical perspective, using newspaper articles, movie reviews, and the books that have gone before (Kanfer points out, a little defensively for my tastes, that Groucho told so many tall tales you couldn't take first-person testimony at face value anyway). "Groucho" makes for an effective (if somewhat detached) bio: overall quite entertaining, not skimping on Marx's low points and somewhat pessimistic worldview as well as his more familiar triumphs. By all accounts, including this one, Groucho was not a guy you'd want to pal around with unless you had the sharpest wit (and even then he'd dislike any attempt to outshine him), and Kanfer does a credible job of portraying Groucho's sourness as well as handling a controversial subject: just how badly Groucho was treated by women in his later years (and to be perfectly fair, his less-than-stellar treatment *of* women throughout his whole life). I have to praise an aspect of this book not many other reviewers have mentioned: it is immensely funny, not because Kanfer is a humorous writer, but because he has the good sense to occasionally step aside and recount some of Groucho's funniest lines or dialogue. Still, the occasional sloppiness in writing and editing (as mentioned by other Amazon reviewers) did make me scowl once in a while as I read it. I wouldn't call this the definite Groucho bio-- but it's an entertaining read and a decent synthesis of the many books I've read before with a slightly fresh spin. Still, given Groucho's disarming, misleading wit about anything personal, can there *ever be* a definitive bio? I'm eagerly awaiting Simon Louvish's "Monkey Business"--given his excellent *and* entertaining W.C. Fields bio, perhaps it's Louvish who can best do justice to the Marxes--but with this enigmatic cult icon whose greasepaint mustache and quick words hid a much more complex man, I wouldn't be surprised if Groucho's up there having a good old laugh on all of us who are trying to analyze his wit rather than just enjoy it.
