Tim Scully manufactured San Francisco's purest and most potent LSD in the mid-1960s. He worked under the tutelage of Augustus Owsley Stanley III, the eccentric Grateful Dead patron and acid enthusiast who's reds and greens and blues made Haight-Ashbury the acid Mecca. Scully, an engineer by training, designed sound equipment for the Dead. Both travelled with the Merry Pranksters—Scully, of course, rigged the sound system on Kesey's bus.
After Owsley's arrest in 1967, Scully synthesized LSD for the Brotherhood of Eternal Love, a spiritual group that sought to turn the entire world onto acid. The police eventually caught up with Scully, but before he was imprisoned, he started his own company designing biofeedback machines. In the late 1980s Scully began consulting for Autodesk (ADSK), writing device drivers for video displays and other equipment. He retired from the company as a senior software engineer in 2005. He renounced drugs in 1970.
