John W. Cowdery (c. 1835-1889) was born in an unknown location and died in West Haven, Connecticut. He was one of the first graduates of the University of Michigan's law school. By 1886, he was a self-proclaimed mindreader and faith cure scientist. According to Nettie D. Lowery, he was teaching Christian Science in Hartford, Connecticut, and claiming to have studied with Mary Baker Eddy, but there are no records that he ever did so.
