The Intercollegiate Bureau of Academic Costume (IBAC) must have assigned Chapman College a hood lining in the late 1940’s or 1950s, as the first IBAC description of the university’s hood is from a 1972 list where it is said to be lined cardinal with a “gray stripe [on] each side”. Whether this described a horizontal or vertical stripe is not known because a vintage Chapman College hood has not been located. Lists compiled by Kevin Sheard in Academic Heraldry in America (1962) and Academic Dress and Insignia of the World (1970) described Chapman’s hood lining as cardinal with a “small gray chevron on each side” of the hood’s lining that were “hidden when worn”. Here the IBAC design has been used, with the “gray stripe” interpreted as a horizontal bar.
