Emanuel Mendel
Emanuel Mendel (1839-1907) was a German neurologist and psychiatrist who was a university professor and director of a policlinic in Berlin. He was founder and publisher of the Neurologisches Centralblatt. Two of his better-known assistants were Max Bielschowsky (1869-1940) and Edward Flatau (1869-1932).
Mendel is best remembered for the introduction of duboisine as a treatment for Parkinson's disease. Duboisine is an extract from the Australian plant Dubosia myoporoides. Mendel was an advocate concerning the unification of psychiatry and neurology as complementary disciplines. He also did important studies of epilepsy and progressive paralysis.
Among his medical writings is a textbook on psychiatry titled A Psychological Study of Insanity for Practitioners and Students, which has been translated into English.
