Harvard Unit Armband, 1916
According to the newspaper coverage, “The only identifying insignia that the surgeons and nurses got at the start, at least, were tags for their hand-baggage, containing their names and the number of their staterooms on board the steamer Andania; and white arm-bands, with the Gothic letters in crimson, “H.U.,” which stands for Harvard University, as well as for Harvard Unit.” Blanche Wallace is one of the nurses in the newsclipping; they all, along with Hugh Cabot, who was in charge of the third unit, are wearing the identifying arm badge.
