Keeper Trout (born October 1957), also known as Keeper of the Trout, is an American independent scholar in the area of psychedelics and psychedelic plants, especially cacti.[1][2][3][4] He is variously described as an author, photographer, ethnobotanist, archivist, and conservationist.[1][3][4]
Trout first became interested in the psychedelic experience in 1972 when he was 14 years old.[1][5] He studied chemistry and microbiology at university in Texas.[4] Trout worked as a lapidarist but eventually was unable to continue doing this work due having come down with encephalitis which had led to unilateral blindness and loss of his depth perception.[5] In 1991, he pivoted direction and started working more publicly in the area of psychedelics.[5] In 1993, he met Alexander and Ann Shulgin and others at a psychedelic conference and they encouraged him to start writing.[1][5] He has since written numerous books and other publications on psychedelic plants and alkaloids, including his notable Trout's Notes series.[1][2][3][4][5] His books are published by Mydriatic Productions, a division of Better Days Publishing.
Trout was formerly a technical editor of the Entheogen Review.[3][4] He is a co-founder and board member of the Cactus Conservation Institute and a board member of the Chihuahuan Desert Preserve Association.[1][6][3][5] He does work for Erowid and Transform Press, is a board member of the Shulgin Farm, and works at the Shulgin Archive digitizing the materials of Alexander Shulgin.[1][3][5]
