Alexander Gill took his M.A. from Corpus Christi College Oxford in 1589. He was high master at St Paul's School from 1608 to 1635. There he succeeded Richard Mulcaster, who had once taught Spenser at Merchant Taylors' School. Gill, or perhaps his son of the same name, was an acquaintance of George Wither. His most famous pupil was John Milton.
