The Selective Service Act of May 18, 1917, established local civilian boards, members of which were nominated by the governor and appointed by the president, to organize a draft of male citizens, and all males not alien enemies who had declared their intention to become citizens, between the ages of 21 and 30 (expanded in 1918 to males between 18 and 45). Harry Parker Hammond served as chairman of the local board for Division 58, New York City, under the Selective Service Act. In 1950, when he donated these materials, he was dean of the College of Engineering at Penn State.
