Born 13 Jun 1854; died 6 Apr 1942 at age 87.U.S. naval officer and inventor whose new instruments greatly improved the efficiency and effectiveness of late 19th-century warships. In 1898, while the navigator of the gunboat Petrel during the Battle of Manila Bay, he determined the ranges of enemy ships for use by the gunners by using his own invention, a stadimeter range finder. Fiske's prolific activity as an inventor began in the mid-1870s with some applications in each World War. His major inventions in electrical and gun-control systems included range finding, ammunition hoists and gun-turret motors and torpedo radio control.
