CAIUS (Anglice, KEES, KEYS, etc.), JOHN English physician, and second founder of the present Gonville and Caius college, Cambridge, was born at Norwich, Oct. 6, 151o. He was admitted a student at what was then Gonville hall, Cam bridge, where he seems to have studied divinity. In 1533 he visited Italy, where he studied under the celebrated Montanus and Vesalius at Padua, taking his degree in physic in 1541. After an extended tour in Europe, he practised in London, being for some years president of the College of Physicians. In 1557 he enlarged the foundation of his old college, named it "Gonville and Caius college," and endowed it with several considerable estates. In Jan. 1559 he accepted the mastership of the college, an office which he held until a month before his death on July 29, By obtaining a grant in 1564 for the college to have annually the bodies of two malefactors for dissection, Dr. Caius became a pioneer in advancing the study of anatomy.
His works, together with the Memoir by John Venn, have been edited by E. S. Roberts (1912) .
