an English physician, and second founder of the present Gonville and Caius College, Cambridge. In 1557 Caius, at that time physician to Queen Mary, enlarged the foundation of his old college, changed the name from "Gonville Hall" to "Gonville and Caius College," and endowed it with several considerable estates, adding an entire new court at the expense of £1,834. He accepted the mastership of the college 24 January 1559 on the death of Dr Bacon, and held it until about a month before his own death.
