Karl Jaspers

German-Swiss psychiatrist and philosopher (1883–1969)

Karl Theodor Jaspers (German: [kaʁl ˈjaspɐs] ; 23 February 1883 – 26 February 1969) was a German-Swiss psychiatrist and philosopher who had a strong influence on modern theology, psychiatry, and philosophy. His 1913 work General Psychopathology influenced many later diagnostic criteria, and argued for a distinction between "primary" and "secondary" delusions. After being trained in and practising psychiatry, Jaspers turned to philosophical inquiry and attempted to develop an innovative philosophical system.
