(1854-1932) US entrepreneur and inventor who founded the Eastman Kodak photographic company 1892. He patented flexible film 1884, invented the Kodak box camera 1888, and introduced daylight-loading film 1892. By 1900 his company was selling a pocket camera for as little as one dollar.
The films first worked with chemicals fixed to a paper base 1884 and later on celluloid 1889. In 1928 he perfected a film process for color photography and development, an important service offered on fine papers. He was known for his contributions to education and music.
Eastman was born in Waterville, New York, and left school at 14. In 1879 he patented a photographic-emulsion coating machine, and began mass production of dry plates in Rochester, New York. In 1886 he introduced stripping film, in which paper was used only to support the emulsion and was stripped off once the negative had been transferred to glass. The image on the glass then had to be transferred to a gelatine sheet for printing. The first Kodak camera was sold loaded with a roll of the stripping film large enough for 100 exposures. After use, the camera was sent to Rochester, where the film was developed and a new film loaded.
Eastman followed this up 1889 with the first commercially available transparent nitrocellulose (celluloid) roll films; the flammable nitrocellulose was later replaced by nonflammable cellulose acetate. Eastman's roll film replaced his stripping film in the Kodak camera and ushered in the era of press-button photography.
