Arnold Weissberger, Research Laboratories, Eastman Kodak Company, Rochester, New York.Edward Curtis Taylor, Jr. was an American chemist who designed and synthesized the chemotherapy drug pemetrexed, an inhibitor of purine biosynthesis, with grant support from the U.S. National Cancer Institute, NIH. Taylor studied for his PhD from 1946 to 1949 at Cornell University with Professor Cornelius Cain.
