 The city has produced a number of scientists, including 19th-century chemist Humphry Davy (who worked in Hotwells). Physicist Paul Dirac (from Bishopston) received the 1933 Nobel Prize for his contributions to quantum mechanics. Cecil Frank Powell was the Melvill Wills Professor of Physics at the University of Bristol when he received the 1950 Nobel Prize for, among other discoveries, his photographic method of studying nuclear processes. Colin Pillinger was the planetary scientist behind the Beagle 2 project, and neuropsychologist Richard Gregory founded the Exploratory (a hands-on science centre which was the predecessor of At-Bristol).
