Gerhard Schmidt, M.D. (1901-1981)
Dr. Gerhard Schmidt was "a world authority on nucleic acids and phospholipids" . Due to the crisis in Europe during the 1930's, Dr. Schmidt came to America and "was involved with medical school for almost forty years" . "During this time he and Dr. Siegfried Thannhauser made a ground-breaking discovery regarding the development of nucleic acid metabolism, introducing a quantitative method for determining DNA and RNA in tissues. The simplicity and reliability of the method continues to play an important role in molecular biology research."
