The Electro-Dynamic Company manufactured electric motors and generators 1880-2000, principally as a subsidiary of the Electric Boat Division of General Dynamics and its predecessors.
History
The company was founded by electrical inventor William Woodnut Griscom in 1880. An important early customer for electric boat motors was the Electric Launch Company, also known as Elco. Following an 1892 bankruptcy, financier Isaac Rice bailed out Electro-Dynamic and became a co-owner. Griscom died in a hunting accident in 1897. Electro-Dynamic manufactured the main propulsion motor for USS Holland, the United States Navy's first modern submarine, launched in 1897.[1] In 1899, Rice founded Electric Boat and made Electro-Dynamic and Elco subsidiaries of it. Electro-Dynamic, relocated from Philadelphia, Pennsylvania to Avenel, New Jersey, went on to manufacture electric motors and generators for numerous submarines built by Electric Boat as well as naval and civilian boats built by Elco. The company retained this function as a division of General Dynamics Corporation when that company was formed by a reorganization of Electric Boat in 1952.[2] The company was dissolved in 2000 and its functions were relocated to Electric Boat's main facility in Groton, Connecticut.[3][4]
