Washington, DC: (Jenkins Laboratory Inc.. 1925). First. First edition. Finely ribbed blue cloth with gilt on the cover and spine. Fine with tiny bump at the base of the spine. With bookplate and owner Signature of Mahlon W. Kenney, an electrical engineer for Grunow Radios and Seeburg Corporation, who invented the iconic Wall-O-Matic diner jukebox. Laid in are two Jenkins Laboratory pamphlets ("Movies by Radio" and "Suggestion for Receiving Radiomovies"), a printed technical drawing for an "Ideal Radio Vision Receiver," and a captioned photograph issued with the book of a technical device with the laboratory stamp on the back. Jenkins, who was a co-inventor of the film projector (his early patents were acquired by Edison), pioneered a mechanical method of wireless transmission of synchronized sound and images, and opened the first broadcasting television station in the U.S. His mechanical technologies were eventually eclipsed by an electronic form of television, but to this day The Academy of Television Arts & Sciences presents a special Emmy Award in his honor. While the book itself is not rare, it is seldom found in such nice condition and never with the laid in ephemera and photograph. . (Inventory #: 410493)
