John Taverner (c. 1490–1545) is regarded as the most important English composer of his day. He was also an organist. Taverner was the first Organist and Master of the Choristers at Christ Church, Oxford, appointed by Thomas Cardinal Wolsey in 1526. The college had been founded in 1525 by Wolsey, and was then known as Cardinal College. Immediately before this, Taverner had been a clerk fellow at the Collegiate Church of Tattershall, Lincolnshire. In 1528 he was reprimanded for his (probably minor) involvement with Lutherans, but escaped punishment for being "but a musician".
