He is a naturalized citizen of the United States. Crabtree is particularly known for his work on "Crabtree's catalyst" for hydrogenations, and his textbook on organometallic chemistry. Education Robert Howard Crabtree studied at Brighton College (1959–1966), and earned a Bachelor of Arts degree from the University of Oxford where he was a student at New College, Oxford in 1970, studying under Malcolm Green. He received his PhD from the University of Sussex in 1973, supervised by Joseph Chatt. Career and research After his PhD, he was a postdoctoral researcher with Hugh Felkin at the Institut de Chimie des Substances Naturelles at Gif-sur-Yvette, near Paris. He was a postdoctoral fellow (1973–1975) and then attaché de recherche (1975–1977). At the end of that time he was chargé de recherche. In 1977 Crabtree took an assistant professorship in Inorganic Chemistry at Yale University. He served as associate professor from 1982 to 1985, and as full professor from 1985 to 2021. In retirement, he now serves as an emeritus professor of chemistry.
