Archbishop of Canterbury, the fourth son of Hugh Courtney, earl of Devonshire, by Margaret, granddaughter of Edward I. He was educated at Oxford, and, though possessed of abilities, owed his elevation in the church to the consequence of his family. When twenty-eight, he was made bishop of Hereford, and afterwards translated to London, where he summoned before him the great Wickliffe, in St. Paul's Cathedral, 1377. The bold reformer was on this occasion attended by his friends John of Gaunt and Lord Percy, who, in supporting his tenets, treated the prelate with such asperity, that a tumult was excited among the citizens of London. Courtney was made chancellor, 1381, and afterwards raised to the see of Canterbury. He was a violent persecutor of the Wickliffites, and condemned their tenets in a synod. He died at Maidstone, 1396, aged 55.
