Heim, Roger (1900-)

French botanist who specialized in cryptogamy and contributed to knowledge of the hallucinogenic properties of mushrooms. He was born on February 12, 1900, in Paris. He studied at the University of Paris (D.Sc., 1931) and Uppsala University, Sweden (Hon. Ph.D.). Heim was appointed director of the French National Museum of Natural History, and also served as director of the laboratory for the study of mycology and tropical phytopathology at the Ecole Pratique des Hautes Etudes. His interest in parapsychology was stimulated by his studies of psychedelic drugs, especially those to be found in mushrooms. He wrote scholarly articles on the sacred mushroom rites of Mexican Indians.
