Augustus Owsley Stanley III (January 19, 1935 – March 12, 2011) was an American-Australian audio engineer and clandestine chemist. He was a key figure in the San Francisco Bay Area hippie movement during the 1960s and played a pivotal role in the decade's counterculture. Under the professional name Bear, he was the sound engineer for the rock band the Grateful Dead, recording many of the band's live performances. Stanley also developed the Grateful Dead's Wall of Sound, one of the largest mobile sound reinforcement systems ever constructed. Stanley also helped Robert Thomas design the band's trademark skull logo. Called the Acid King by the media, Stanley was the first known private individual to manufacture mass quantities of LSD. By his own account, between 1965 and 1967, Stanley produced at least 500 grams of LSD, amounting to a little more than five million doses. He died in a car accident in Australia (where he had taken citizenship in 1996) on March 12, 2011. Ancestry Stanley was the scion of a political family from Kentucky. His father was a government attorney. His paternal grandfather, Augustus Owsley Stanley, a member of the United States Senate after serving as Governor of Kentucky and in the U.S. House of Representatives, campaigned against Prohibition in the 1920s. Biography Early life When he was fifteen, Owsley spent fifteen months as a voluntary psychiatric patient in St. Elizabeths Hospital in Washington, D.C. Without having graduated high school, he was admitted to the University of Virginia, where he studied engineering for a year. Despite maintaining a 3.4 grade point average with minimal effort, he dropped out because of his disinclination for slide rules and mechanical drawing. Belying his dearth of formal education, he secured a position as a test engineer with Rocketdyne in Los Angeles; in this capacity, he worked on the SM-64 Navaho supersonic cruise missile. In June 1956, he enlisted in the United States Air Force as an electronics specialist, serving for 18 months (including stints at the Jet Propulsion Laboratory and Edwards Air Force Base's Rocket Engine Test Facility) before being discharged in 1958. During his service, he secured an amateur radio license and a general radiotelephone operator license. Later, inspired by a 1958 performance of the Bolshoi Ballet, he studied ballet in Los Angeles, supporting himself for a time as a professional dancer. In 1963, he enrolled at the University of California, Berkeley, where he
