Frank Taylor Cable (19 June 1863 – 21 May 1945) was an early pioneer in submarine development and piloted the first United States Navy submarine, during its pre-commissioning trials. Early life and education Cable was born in New Milford, Connecticut, where his father was a farmer. He attended Claverack College in Hudson, New York, followed by Franklin Institute and Drexel Institute in Philadelphia. Career Cable was employed by the Electro-Dynamic Company owned by financier Isaac Rice and William Woodnut Griscom. Rice was a financial supporter of inventor John Phillip Holland, whose Holland Torpedo Boat Company (the forerunner and precursor to the Electric Boat Division of General Dynamics Corporation) was developing a prototype submarine, Holland VI, for the United States Navy. When Holland VI accidentally sank with its hatches open in New York harbor on 13 October 1897, Cable was dispatched by Rice to assist with the repairs. The submarine's internal components had been flooded with corrosive salt water, leading to short circuits and corrosion. Cable had previously specialized in the design and production of propulsion machinery, including diesel engines and electric motors and was able to co-ordinate repair work and restore the submarine's operations. Cable was retained as an electrician at Holland's company — while still working for Rice — and made a number of changes to the submarine design. A key proposal of Cable's was to improve the submarine's handling by relocating the rudder and stern diving planes aft the propeller. The proposal was accepted and by 4 July 1898 Holland VI was ready for sea trials. Cable was chosen as the civilian trial captain and successfully commanded the vessel during its early operations. Holland VI was purchased by the United States Navy on 11 April 1900 with the initial designation of and the subsequent designation of SS-1. The craft was officially commissioned into U.S. Navy service on 12 October 1900. In 1902, Cable supervised the building of five submarines in England. Following the commissioning of USS Holland, Cable was engaged to train prospective submarine crews in Britain, Japan and Russia. Upon his return to the United States in 1905, he went on to become a co-founder of the Electric Boat Company, based in Groton, Connecticut, the primary manufacturer of United States submarines. He was appointed company general manager in 1930 and died in 1945. Cable worked for Electric Boat for nearly 45 years. In 1910, Frank Cable and
