Emily Davenport's wedding dress was responsible for the electric motor. In the spring of 1833 her husband Thomas Davenport heard some curious news that changed his life (and her gown). The momentous news that roused the blacksmith's curiosity was that the Penfield and Hammond Iron Works was using a new method for separating crushed ore using a magnet developed by Joseph Henry Thomas Davenport had no prior knowledge of discoveries in magnetism and electricity when this new process stimulated his interest. With her husband Thomas Davenport and his colleague Orange Smalley, Emily Davenport invented the electric motor and electric locomotive circa 1834. She cut up her wedding dress into strips of silk to insulate the wire windings.
