Fritz Morgenthaler (1919-1984) was a prominent Swiss physician, psychoanalyst, ethnologist, and painter. Cofounder of the interdisciplinary field of ethnopsychoanalysis, his writings on clinical practice, sexuality, and dream interpretation were essential reading for the counterculture and New Left in Continental Europe.
