Battenberg's Course Indicator

Description:

This mechanical device, designed to solve problems involving the relative velocities of two ships at sea, was invented in 1902 by Louis Battenberg in England. The inscriptions read "Battenberg’s Course Indicator U.S. Navy Mark II" and "F.A./J.Q.M. 1924."

Born in the Prussian province of Hesse-Nassau, Louis Battenberg (1854-1921) became a British citizen in 1868 and a cadet in the Royal Navy. He rose quickly through the ranks, becoming eventually Commander-in-Chief of the Atlantic Fleet, Admiral, and then First Sea Lord. He changed his name to Mountbatten in 1917 and relinquished his German title in favor of a British one.
