In this paper Korn gives a technical decription of his invention of his telephotographic machine (later the fax-machine)
In 1902, Arthur Korn (1870-1945) in Germany invented telephotography, a means for transmitting still photographs by means of electrical wires. In 1907, Korn sent the first inter-city fax when he transmitted a photograph from Munich to Berlin. By 1906 his equipment was being put into regular service for transmission of newspaper photographs between Munich and berlin via telegraph circuits. (Hook & Norman "Origins of Cyperspace", No. 171).
