Quain Professor is the professorship title for certain disciplines at University College, London, England. The title is derived from Richard Quain (1800-1887) who became professor of anatomy in 1832 at what was to become UCL. He made a provision in his will to the University that endowed professorships for four subjects; intending that funding gave recognition to his brother, John Richard Quain, as well as his own.
The Burhop prize for Physics, Applied Physics or Mathematics/Physics is also drawn from these funds.
The Quain professorships are of Botany, English language and literature, Jurisprudence, and Physics.
