As a teenager, Karl Hans Janke attended a technical college to study dentistry. Recruited into the army in 1940, he was finally released in 1943 on medical grounds. Hospitalized from the 1950s at the Hubertis Wermsdorf Psychiatric Hospital in the German Democratic Republic, he produced more than 4,500 drawings, representing technological inventions, the main ones being flying machines. His visions of intergalactic travel, the cosmos, and the origins of life were for him “for the benefit of mankind and aimed at promoting peace.” The hospital staff encouraged him to develop his work and he had his own studio. Karl Hans Janke’s work was not rediscovered until 2000.
