Karl Jaspers
Karl Theodor Jaspers (; ; 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. He was often viewed as a major exponent of existentialism in Germany, though he did not accept the label. Provided by Wikipedia
