The academic and avocational pursuits of the faculty often reveal curious and unsuspected combinations of interests. Robert M. Grant, Carl Darling Buck Professor Emeritus in the Department of New Testament and Early Christian Literature in the Divinity School, has spent a distinguished career teaching and writing prolifically in the field of early Christianity, touching on such subjects as the New Testament, early Christian thought, patristics, and Gnosticism. Yet his earliest publications, appearing in 1938 when he was twenty-one, were entitled "Known Sunk: German Submarine War Losses," and "The Uses of Mines Against Submarines." These articles point to another, less visible interest, which began when he was nine years old. Grant maintained his interest in submarines throughout his career, and wrote two authoritative books on the subject as well as a number of articles. This exhibition, which may surface as a surprise to some, is drawn from Professor Grant's research collection, and is one of a series of exhibits highlighting the breadth and variety of the University of Chicago faculty's private collections.
