Kodak's origins rest with Eastman Dry Plate Company, and the General Aristo Company, founded by inventor George Eastman in Rochester and Jamestown, New York. The General Aristo Company was formed in 1899 in Jamestown New York, with George Eastman as treasurer, and this company purchased the stock of American Aristotype Company. George Eastman registered the trademark Kodak on September 4, 1888. The Eastman Kodak Company was founded by Eastman in 1892. He also coined the advertising slogan, "You press the button, we do the rest."
