Robert Bosch and his own Robert Bosch foundation opened a homeopathic clinical and research hospital with about 200 beds in Stuttgart in 1940. However, in 1956 Homeopathy disappeared in the internal medicine department. By 1973 the homeopathic outpatient department was also closed. That means research aspiration could only be performed during the first few years. In 1980 the Institute of History of Medicine (IGM) of the Robert Bosch foundation was founded. This is the only extra-university institute of history of medicine in Germany.
The Karl and Veronica Carstens foundation, named after the former president of Germany Karl Carstens (1979-1984) and his wife Veronica Carstens is promoting Naturopathy and Homeopathy since 1982 especially on the university level. During the Winter semester 2014/15 homeopathy could be studied as elective subjects at 8 universities[i].
