Schick U.S. Navy Stadimeter
1943 Schick incorporated U.S. Navy Stadimeter,
The stadimeter was developed in the 1890s by Bradley Allen Fiske (1854-1942), a Lieutenant in the United States Navy who had access to a laboratory in New York City that was fully backed by the Western Electric Manufacturing Co. The instrument was designed to determine the distance to an enemy warship, the mast head height of which was easily found in the naval literature. Although Fiske obtained several patents for rangefinders during the 1890s, it is not yet clear which of these patents pertained to the stadimeter.
