German neuropsychiatrist who was a pioneering student of sexual psychopathology.

Educated in Germany and Switzerland, Krafft-Ebing was appointed professor of psychiatry at Strasbourg at the age of 32. His interests ranged from genetic functions in insanity and sexual deviation to epilepsy, paralysis agitans, and hemicrania. He also established the relationship between syphilis and general paresis and performed experiments in hypnosis. Krafft-Ebing is best known today for his Psychopathia Sexualis (1886), a groundbreaking examination of sexual aberrations.
