His obit is in the NYT here.
And there's a 2007 article about him in Rolling Stone here.
Over the course of the next fourteen years, Owsley — known to his friends as "Bear" because of his prematurely hairy chest as a teenager — enlisted in the Air Force, became a ham- radio operator, obtained a first-class radiotelephone operator's license, worked at the Jet Propulsion Laboratory in Pasadena, California, and served as a summer-relief broadcast engineer at TV and radio stations in Los Angeles. He married and divorced twice, fathered two children and got himself arrested on a variety of charges. He also studied ballet, Russian and French.
