This is the website dedicated to the study of Captain Al Hubbard. Here is a bit from the site.
For such a pivotal character in recent history, Al Hubbard is remarkably little known. He is the unsung man who almost single-handedly introduced the world to LSD, as well as (to a lesser degree) mescaline and psilocybin. Albert Hoffman may have invented LSD, but Hubbard is the one who, in the very early years, gave it away like candy to some of the most influential people on the planet. A true cipher, Hubbard was visionary, eccentric, friendly, and mysterious. At various times, he was an intelligence agent, an inventor, a millionaire, a clinical therapist, and more. There appear to be links between Hubbard and MKULTRA, the CIA program that researched behavior modification using LSD and other substances and techniques.
This site began as a work-in-progress, created when we started researching In Search of the Ultimate High. The archive contains some of the writing that is in the book itself, some partly-edited material, accounts that we regretfully did not have space to include, and much more
Bibliography based on independent research conducted primarily from 1985-1993 reviewing the available literature on the subject of psychedelic drugs.
