The university's position of Savilian Professor of Astronomy was established in 1619. It was founded (at the same time as the Savilian Professorship of Geometry) by Sir Henry Savile, a mathematician and classical scholar who was Warden of Merton College and Provost of Eton College. He appointed John Bainbridge as the first professor. There have been 21 astronomy professors in all; Steven Balbus, the current professor, was appointed in September 2012. Past professors include Christopher Wren (1661–73) (pictured), architect of St Paul's Cathedral in London and the Sheldonian Theatre in Oxford; he held the professorship at the time of his commission to rebuild the cathedral after it was destroyed by the Great Fire of London in 1666. Three professors have been awarded the Gold Medal of the Royal Astronomical Society: Charles Pritchard (1870–93), Harry Plaskett (1932–60) and Joseph Silk (1999–2012). The two Savilian chairs have been linked with professorial fellowships at New College since the late 19th century. The astronomy professor is a member of the Sub-Department of Astrophysics at Oxford.
