Biography of Leonor Michaelis
Leonor Michaelis studied in Berlin and Freiburg im Breisgau. He graduated in Freiburg in 1897 and received his doctorate in Berlin that year. He was then private assistant to Paul Ehrlich (1854-1915) in Berlin 1898-1899, assistant to Moritz Litten (1845-1907) in the Berlin city hospital at Urban 1899-1902, and 1902-1906 with Ernst Viktor von Leyden (1832-1910) in the cancer ward of the I. medical clinic. From 1906 to 1922 Michaelis was head of the bacteriological department at the Urban hospital, becoming professor extraordinary 1908.
From 1922 to 1926 Michaelis was professor of biochemistry at the University of Nagoya, Japan, and 1926-1929 resident lecturer in medical research at the Johns Hopkins University in Baltimore. From 1929 to 1940 he was with the Rockefeller Institute of Medical Research in New York. His main field of work was physical chemistry, in particular its use in biology and medicine.
Michaelis developed the equation with Menten to explain the relationship of the concentration of reactants on enzyme catalysed reactions. He discovered Janus Green and was the pioneer of the permanent wave since he found that keratin was soluble in thioglycolic acid. He died in New York City.
