Matthew Parker (1504-1575) was one of the White Horse Inn members and one of the Marian exiles. On his return he was made Archbishop of Canterbury (1559-1575) by Elizabeth I. It was thought she appointed him as he was a moderate man.
Parker was a keen bibliophile and his library was bequeathed to Corpus Christi College, Cambridge. Under Henry VIII Parker had been the Master of Corpus Christi. He was a friend of Martin Bucer and preached at Bucer's funeral in 1551.
He played a key role in the Book of Common Prayer and helped produce the Bishop's Bible.
