Alexander "Sasha" Theodore Shulgin (born June 17, 1925) was an American pharmacologist, chemist and drug developer.
Shulgin was credited with the popularization of MDMA, commonly known as ecstasy, in the late 1970s and early 1980s, especially for psychopharmaceutical use and the treatment of depression and post-traumatic stress disorder. In subsequent years, Shulgin discovered, synthesized, and bioassayed over 230 psychoactive compounds. In 1991 and 1997, he and his wife Ann Shulgin authored the books PiHKAL and TiHKAL on the topic of psychoactive drugs. Shulgin discovered many noteworthy phenethylamines including the 2C* family of which 2C-T-2, 2C-T-7, 2C-E, 2C-I, and 2C-B are most well known. Additionally, Shulgin performed seminal work into the descriptive synthesis of compounds based on the organic compound tryptamine.
