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.
