Ralph Hubert "Sonny" Barger (born October 8, 1938) is an American author, actor, outlaw biker and convicted felon, who is a founding member (1957) of the Oakland, California chapter of the Hells Angels Motorcycle Club. He is the author of five books – Hell's Angel: The Life and Times of Sonny Barger and the Hell's Angels Motorcycle Club (2000), Dead in 5 Heartbeats (2004), Freedom: Credos from the Road (2005), 6 Chambers, 1 Bullet (2006), and Let's Ride: Sonny Barger's Guide to Motorcycling (2010) – and editor of the book Ridin' High, Livin' Free: Hell-Raising Stories (2003). Onscreen, Barger was identified but did not speak in Hells Angels on Wheels (1967) and was one of several members of the Angels who had speaking parts playing themselves in Hell's Angels '69 (1969); he has appeared in several additional films. He also appeared in the Sons of Anarchy television show as Lenny "The Pimp" Janowitz.
Barger features prominently in Hunter S. Thompson's book, Hell's Angels: The Strange and Terrible Saga of the Outlaw Motorcycle Gangs (1966). Barger and the Hells Angels are also depicted in Tom Wolfe's The Electric Kool-Aid Acid Test (1968), during Ken Kesey's La Honda encampment. Barger was one of the Hells Angels present at the Rolling Stones' Altamont Free Concert in 1969, and appears in the documentary film about the concert: Gimme Shelter (1970).
In 1983, Barger was diagnosed with throat cancer, after years of heavy smoking. His diagnosis and treatment was at Ft. Miley VA Hospital in San Francisco. Having Stage III Laryngeal Cancer, a Total Laryngectomy with Bilateral Functional Neck Dissections was performed by Michael Tralla MD FACS. Consequently since his vocal cords were removed, he learned to vocalize using the muscles in his esophagus.
In 1988, Barger was found guilty of conspiring to blow up the clubhouse of a rival motorcycle club, The Outlaws in Louisville, Kentucky, and spent four years in federal prison in Arizona.
Sonny Barger remains an active member of the Hells Angels in the Cave Creek, Arizona Chapter, having moved there from Oakland in 1998.
In recent years, Barger has worked to promote motorcycle safety; he co-authored a book on the subject with Darwin Holmstrom (the author of The Complete Idiot's Guide to Motorcycles (1998)) titled Let's Ride: Sonny Barger's Guide to Motorcycling (2010).
In terms of pure workmanship, personally I don't like Harleys. I ride them because I'm in the club, and that's the image, but if I could I would seriously consider riding a Honda ST1100 or a BMW. We really missed the boat not switching over to the Japanese models when they began building bigger bikes. I'll usually say "Fuck Harley-Davidson." – Ralph "Sonny" Barger, Hell's Angel
On November 30, 2010, Barger made a guest appearance as Lenny "The Pimp" Janowitz on the Season 3 finale of the FX television series Sons of Anarchy, about a fictional outlaw motorcycle club, allegedly based on the Hells Angels.
