Camouflage
When Berry returned to the U.S. in 1915, he moved to New York, where he earned his living as a commercial artist. Soon after, he married, and he and his wife raised a son. In 1917, when the U.S. entered World War I, he volunteered for service. He was commissioned as a first lieutenant, and assigned to camouflage. According to Rickard (1942, p. 190), Berry was one of the first seven officers (nearly all of whom were either artists or architects) attached to the American Camouflage Corps, along with Homer Saint-Gaudens, Evarts Tracy, Aymar Embury, Andre Smith, Lawrence Hitt and Victor White. In December 1918, he and his unit were shipped to France (Behrens 2009), where they spent the remainder of the war.
