John Crayford (died 1547) was a Master of both Clare College, Cambridge, and University College, Oxford, England.[1][2] Martyn was unusual in being a Master of colleges at both the universities of Oxford and Cambridge. He was the only Master of University College to also have been a Master at a Cambridge college.
Crayford was a Fellow at University College in the early 1520s.[3] He was Master of Clare College, Cambridge from 1530 to 1539 and Vice-Chancellor of the University of Cambridge during 1534–36.[4] He helped in the university's support for Henry VIII's divorce from Catherine of Aragon in 1533. From 1545 to 1547 he was Archdeacon of Berkshire.[5]
Later he became Master of University College from 1546 until his unexpected death in August 1547, only a year later.
