On July 2, 1974, I started work as deputy Washington bureau chief for Rolling Stone magazine. My unlikely boss was Richard Goodwin, the former Kennedy speechwriter, who invited me to join him in temporary residence at Ethel Kennedy’s home in McLean, Va. (the owner was in Hyannis for the summer). On July 3, Hunter Thompson joined us. Much of what ensued that holiday weekend is lost in the mists of history and a fog of controlled substances. There were extensive conversations about the viability of renting a truck, filling it with rats and dumping them on the White House lawn. There was also an effort to remove all the Andy Williams songs from the Kennedy jukebox and replace them with Otis Redding. But mostly I remember having a marathon conversation with Hunter about books and writers, settling finally on Joseph Conrad’s exhortation in “Lord Jim”: “In the destructive element immerse!”

This was, no surprise, one of Hunter’s favorite lines, and it led him into an astonishingly candid assessment of his own career, which was then at its peak. He had published his two brilliant “Fear and Loathing” books, and he was worried about what came next. He didn’t want to become a dull parody of himself but feared he lacked the gumption to jump the gravy train. I asked if he’d ever thought about stowing the psychedelic pyrotechnics — his “gonzo” journalism — and sitting down and writing a serious, straight-ahead novel. Well, of course he had. But, he said, “Without that,” and he glanced over at the satchel in which he carried his array of vegetation and chemicals, “I’d have the brain of a second-rate accountant.”

Hunter Thompson was always much more, and sometimes a bit less, than the sum of his ribald public persona. In compiling this oral history, Jann Wenner and Corey Seymour could easily have succumbed to the same temptation that Hunter did: to celebrate the myth, to recount a numbing parade of hilarious, drug-addled Hunter stories, and to miss the man. Happily, they have produced a rigorous and honest piece of work. “Gonzo” is a wonderfully entertaining chronicle of Hunter’s wild ride, but it is also a detailed, painful account of his self-destructive immersions; the brutality he visited upon his wife, Sandy; and the anguish of a life that veered from inspired performance art to ruinous solipsism. It’s especially good to be reminded that Wenner, in addition to being a successful media mogul and perpetual gossip item, has been a journalist of real distinction, with the ability to find talented editors like Seymour, who, I assume, did most of the actual cutting and pasting to create the book’s unflagging pace from interviews with 112 sources, ranging from Jimmy Carter to Johnny Depp. It was Wenner’s patience and indulgence that enabled Thompson to produce his very best work; Wenner’s vision made Rolling Stone, in the early 1970s, one of the most exciting publications in American history.

Hunter Thompson was born in Louisville, Ky., in 1937 and, from adolescence on, seemed intent on becoming a classic American Literary Character, part of the outlaw slipstream that produced Whitman, Twain, Hemingway, Guthrie, Mailer and Kerouac. This might have been a staggeringly banal career choice — there’s a testosterone-addled, troublemaking puer aeternus spewing fountains of self-absorbed gush in every high school — but Thompson actually turned out to have a distinctly American genius for comic hyperbole. He was the son of an insurance salesman who died when Hunter was in high school and an alcoholic mother who didn’t have a prayer of controlling her wild child. He was antsy, violent, a lover of books and guns, a member of the prestigious Athenaeum Literary Association in Louisville and of a street gang of pranksters, most of whom were sons of prominent families. In his senior year of high school, Thompson was arrested with two others after one in his group stole a man’s wallet — this, after other scrapes with the law — and thrown in jail. Douglas Brinkley, Thompson’s literary executor, recalled: “Hunter wrote his mother these very philosophical letters from behind bars. ... The buddies that he was with ... were waltzing because they knew the judge, ... he was the poor kid on the other side of the railroad tracks with no dad. The game was fixed.” The judge gave Thompson a choice of prison or the military; he chose the Air Force. One senses that Hunter saw the experience mostly as grist for his legend. No doubt it helped solidify his politics, such as they were — a blithe populist libertarianism, unencumbered by doctrine.
