Numerous notable mathematicians, physicians, and scientists have been educated at Jesus College, one of the constituent colleges of the University of Oxford in England. Mathematicians who have studied at Jesus College include Nigel Hitchin (Savilian Professor of Geometry at Oxford since 1997, pictured), Jonathan Borwein (a former Rhodes Scholar who has held professorial appointments in Canada and Australia), and Jim Mauldon (who taught at Oxford before moving to the United States to teach at Amherst College in Massachusetts). Several noted individuals from biology, botany and zoology were educated at the college, including the Welsh clergyman Hugh Davies (whose Welsh Botanology of 1813 was the first publication to cross-reference the Welsh-language and the scientific names of plants). Jesus College had its own science laboratories from 1907 to 1947, which were overseen (for all but the last three years) by the physical chemist David Chapman, a Fellow of the college from 1907 to 1944. At the time of their closure, they were the last college-based science laboratories at the university. Scientific research and tuition (particularly in chemistry) became an important part of the college's academic life after the construction of the laboratories.
