Jenkins was born in Dayton, Ohio, grew up near Richmond, Indiana, where he went to school, and went to Washington, D.C. in 1890, where he worked as a stenographer. He started experimenting with movie film in 1891, and eventually quit his job and concentrated fully on the development of his own movie projector, the Phantascope. At the Bliss School of Electricity in Washington, D.C. he met his classmate Thomas Armat, and together they improved the design. They did a public screening at the Cotton States Exhibition in Atlanta in 1896 and subsequently broke up quarrelling over patent issues. Armat eventually won the case in which Jenkins had tried to claim sole ownership of the patent, and Jenkins sold out to him.
