David Sheff is the author of Clean: Overcoming Addiction and Ending America’s Greatest Tragedy, the follow-up to his New York Times #1 best seller, Beautiful Boy: A Father’s Journey Through His Son’s Addiction. Clean is the result of the years Sheff spent investigating the disease of addiction and America’s drug problem, which he sees as the greatest public health challenge of our time. Writing about Clean, author Benoit Denizet-Lewis says, “David Sheff has written the most important book about addiction in a decade.” Richard Branson says that Clean is “an important expose of a failed system.” Eric Schlosser wrote, “Clean will change not only how you look at drug abuse–but also what you think should be done about it.” Sheff’s Beautiful Boy, published in 2008, was based on his article, “My Addicted Son,” which appeared in the New York Times Magazine. The article won a special award from the American Psychological Association for “outstanding contribution to the understanding of addiction.” Beautiful Boy was named the year’s Best Nonfiction Book by Entertainment Weekly, and it won first place in the Barnes and Noble Discover Award in nonfiction. Sheff also contributed to HBO’s Addiction: Why Can’t They Just Stop. In 2009, he was named to the Time 100, Time Magazine’s list of the World’s Most Influential People. He won the 2013 College of Problems on Drug Dependence (CPDD) Media Award. Along with The New York Times Magazine, Sheff has also written for Playboy, The New York Times, Wired, Rolling Stone, Outside, The Los Angeles Times Magazine, Esquire and Observer Magazine in England, Foreign Literature in Russia, and Playboy (Shueisha) in Japan. He has conducted seminal interviews with John Lennon and Yoko Ono, artist and dissident Ai Weiwei, nuclear physicist Ted Taylor, Congressman Barney Frank, Steve Jobs, Tom Hanks, Betty Friedan, Keith Haring, Jack Nicholson, Carl Sagan, Salman Rushdie, Fareed Zakaria, and others. He also wrote an award-winning documentary about John Steinbeck’s The Grapes of Wrath, and a radio special about Harper Lee’sTo Kill a Mockingbird, both for National Public Radio. Sheff is the author of Game Over, called “the bible of the videogame industry” by The Wall Street Journal, and “beguiling” and “irresistible. . . almost as hypnotic as a successful video game” by The New York Times. Author Gore Vidal said that China Dawn, Sheff’s book about the Internet revolution in China, is a “fascinating…study of go–getting businessmen in a revived China bound to shape our future.” All We Are Saying, based on Sheff’s interviews with John Lennon and Yoko Ono in 1980, was a Literary Guild Selection book. Charles Champlin, Arts Editor of the Los Angeles Times, wrote: ”David Sheff’s sympathetic questions evoked so much of the Beatle past and of Lennon’s intellectual past and present and future plans that the interview would hardly have been less engrossing and important even it if were not illuminated by tragedy.” Sheff graduated from the University of California, Berkeley. He lives with his family in Northern California.
