Biography of Karl Jaspers
Karl Theodor Jaspers (23 February 1883 – 26 February 1969) was a German psychiatrist and philosopher who had a strong influence on modern theology, psychiatry and philosophy. After being trained in and practicing psychiatry, Jaspers turned to philosophical inquiry and attempted to discover an innovative philosophical system. He was often viewed as a major exponent of existentialism in Germany, though he did not accept this label.
Jaspers was born in Oldenburg in 1883 to a mother from a local farming community, and a jurist father. He showed an early interest in philosophy, but his father's experience with the legal system undoubtedly influenced his decision to study law at Heidelberg University. It soon became clear that Jaspers did not particularly enjoy law, and he switched to studying medicine in 1902 with a thesis about criminology. In 1910 he married Gertrud Mayer (1879-1974), the sister of his close friends Gustav and Ernst Mayer.
Jaspers graduated from Heidelberg University medical school in 1909 and began work at a psychiatric hospital in Heidelberg where Emil Kraepelin had worked some years earlier. Jaspers became dissatisfied with the way the medical community of the time approached the study of mental illness and set himself the task of improving the psychiatric approach. In 1913 Jaspers gained a temporary post as a psychology teacher at Heidelberg University. The post later became permanent, and Jaspers never returned to clinical practice. During this time Jaspers was a close friend of the Weber family (Max Weber also having held a professorship at Heidelberg).
At the age of 40 Jaspers turned from psychology to philosophy, expanding on themes he had developed in his psychiatric works. He became a renowned philosopher, well respected in Germany and Europe.
After the Nazi seizure of power in 1933, Jaspers was considered to have a "Jewish taint" (jüdische Versippung, in the jargon of the time) due to his Jewish wife, and was forced to retire from teaching in 1937. In 1938 he fell under a publication ban as well. Many of his long-time friends stood by him, however, and he was able to continue his studies and research without being totally isolated. But he and his wife were under constant threat of removal to a concentration camp until 30 March 1945, when Heidelberg was liberated by American troops.
In 1948 Jaspers moved to the University of Basel in Switzerland. He remained prominent in the philosophical community until his death in Basel on his wife's 90th birthday in 1969.
