The (Grateful) Dead tickets
Owsley Stanley (born Augustus Owsley Stanley III, January 19, 1935) also known as The Bear, was an underground LSD chemist, the first to produce large quantities of pure LSD.
His total production is estimated at around half a kilogram of LSD, or roughly 5 million 100-microgram “trips” of normal potency, although accounts vary widely. The widespread and low-cost (often given away free) availability of Stanley’s high-quality LSD in the San Francisco area in the mid-1960s may have been crucial for the emergence of the hippie movement during the Summer of Love in the Haight-Ashbury area, which one historian of that movement, Charles Perry, has described as “one big LSD party.” Stanley was also an accomplished sound engineer, and the longtime soundman for seminal psychedelic rock band the Grateful Dead; the band’s well-known “dancing bear” icon derives from his nickname.
