4o. Text diagrams. Original plain blue wrappers. Laid in are two photographs transmitted by Korn's telephotography device, dated October 17, 1906, and November 5, 1906. The photographs measure 109 x 83 mm.
Provenance: HENRI BECQUEREL (1852-1908), discoverer of radioactivity, and winner (with Marie and Pierre Curie) of the 1903 Nobel Prize for physics. With Korn's presentation inscription on the front wrapper: "Hommage de l'auteur." Presumably the transmitted photographs were also sent by Korn to Becquerel.
FIRST SEPARATE EDITION. Korn invented telephotography, a means of manually breaking down and transmitting still photographs over electrical wires. Korn's transmitter employed a selenium photocell to sense an image wrapped on a transparent glass cylinder; at the receiver the transmitted image was recorded on photographic film. Korn invented his device in 1902; by 1906 his equipment was being put into regular service for transmission of newspaper photographs between Munich and Berlin via telegraph circuits. OOC 171.
