Inventor. Thomas Davenport, a blacksmith, is credited with constructing the first American DC electric motor in 1834, which was patented the next year, naming co-inventors as his wife Emily and colleague Orange Smalley. His invention was used to power a model railway. Convinced of the motor's commercial possibilities, he moved to New York City and attempted to attract investors by demonstrating how it operated a printing press and other machines. The venture failed because no one could predict the amount of energy available in the primitive chemical batteries then in use, meaning a direct current (DC) motor couldn't compete with the steam engine. Bankrupt, Davenport returned to Vermont and started a book describing his vision for electricity's future, but died just days before his 49th birthday. He did not live to see his invention's worth. By the 1860s, a new generation of inventors determined that Davenport's motor worked in reverse, with water or steam powering it to function as a generator. By the late 1800s, electric trains and trolleys were common, with a Davenport motor generating electricity at a central plant and another converting it to power that moved the cars. Recognizing that increased demand required a larger manufacturing capacity, Thomas Edison started a factory in Schenectady that became General Electric. GE's first products were motors and generators that copied Davenport's, and the realization that his motor generated power by running in one direction and provided it by running in the other led to the creation of alternating current (AC), giving rise to electric lights and other appliances. There is a monument to Davenport in Forest Dale, and the Smalley-Davenport Shop has been the subject of state historic preservation efforts.
