Xerography, a process of producing images using electricity, was invented in 1938 by physicist-lawyer Chester Floyd "Chet" Carlson (1906–1968), and an engineering friend, Otto Kornei. Carlson entered into a research agreement with the Battelle Memorial Institute in 1944, when he and Kornei produced the first operable copy machine. He sold his rights in 1947 to the Haloid Company, a wet-chemical photocopy machine manufacturer, founded in 1906 in Rochester, New York.
