William Woodnut Griscom (c. 1851–1897) was an American inventor, credited with introducing electric motors for the purpose of marine propulsion.
He also founded the Electro-Dynamic Company in 1880, based in Philadelphia, and had around 40 patents to his name.
[1][2] In 1881 The Franklin Institute awarded him what was then their highest honor, the Elliott Cresson Medal, for a combination motor and battery that powered a sewing machine.
[3] In 1892, Isaac Rice bailed Electro-Dynamic out following a bankruptcy and became a co-owner.
He is buried at the Church of the Redeemer Cemetery in Bryn Mawr, Pennsylvania.
