Chemists

Joseph B. Koepfli (1904-2004) was a research associate in chemistry at Caltech from 1932 to 1971. His field of study was organic chemistry, principally alkaloids and other physiologically active substances such as adrenalin and insulin. He was trained in pharmacology and during World War II worked on developing antimalarial drugs. Koepfli's papers document a portion of his chemical research as well as his role as a science adviser to the U.S. State Department.

The Rudolph A Marcus papers consist of working papers, correspondence, publications, and biographical material. Marcus is best known for his contributions to the theory of electron transfer reactions in chemical systems, for which he won the 1992 Nobel Prize in chemistry.
