England’s earliest chair of mathematics was that of Gresham College, founded in 1597, but who came next? The earliest University-based mathematics professorship was Oxford’s Savilian Chair of Geometry, founded in 1619. This illustrated lecture outlines the 400-year history of this Chair, from its beginnings to the present day, and features such figures as Henry Briggs, John Wallis, Edmond Halley, James Joseph Sylvester and G. H. Hardy.
