TRAUBE, MORITZ (1826–1894), German chemist and biologist. Traube was born in Ratibor, Upper Silesia, the brother of Ludwig *Traube. For most of his life he had to combine scientific research in his private laboratory with running the family wine business. With his discovery of semipermeable membranes he pioneered the field of osmosis. He also did research into autoxidation of hydrogen peroxide, plant respiration, biological oxidation and reduction, and nutrition. Traube was a member of the Berlin Academy of Sciences.
