Building 39 was first built as a factory for Vose and Sons pianos in 1922. Two decades later, in 1941, the Army bought seven acres of land, including the building, which was owned by Simmons Mattress Co. From World War II through the early 1950’s, Building 39 housed a machine shop, the machine tool division of the Arsenal’s Apprentice School, and divisions of government agencies, including the U.S. Atomic Energy Commission and the U.S. Air Force Geophysics Laboratory. In 1953, the entire building was converted into the Watertown Arsenal Laboratories, where research focused on metals and ceramics, organic materials and mechanics, and structural integrity. Much of the lab’s work is just beginning to be de-classified.
