William Tyndale was a priest who graduated at Oxford, was a student in Cambridge when Martin Luther posted his theses at Wittenberg and was troubled by the problems within the Church. In 1523, taking advantage of the recent invention of the printing press, Tyndale began to cast the Scriptures into English. His aims were simple but ambitious (as expressed to an educated man): "I defy the Pope and all his laws: and if God spare my life, ere many years I will cause a boy that driveth the plough shall know more of the Scriptures than thou dost." Within his lifetime, only his New Testament and part of his Old Testament were published.
