Bradbrook, M. C. (1978). Shakespeare: The Poet in his World. New York: Columbia University Press, 11. "After two years in the petty school and two or three in the lower school with the usher, Shakespeare would pass at ten or eleven to the upper school and the guidance of the master. From 1575 to 1579 Thomas Jenkins held the post. In spite of his name, he was from not Wales but London, the son of a poor man who was servant to Sir Thomas White. Sir Thomas had founded St. John's College in Oxford and was also a great benefactor of the Merchant Taylors' School in London. If Jenkins, who had graduated from St John's College, had been a pupil at Merchant Taylors' School, he would have been taught by Richard Mulcaster, author of that great educational book the Elementarie and a fervent believer in teaching through play-acting ... Certainly all the masters in his [Shakespeare's] plays ... like putting on plays."
