Abstract :
A RECENT EXHIBIT, entitled “Selected Treasures of the Henry Ford Museum and Greenfield Village,” at the Ford Museum in Dearborn, Mich., included the objects shown at the right as outstanding firsts in the communications field. F. R. Davis, curator of communications, holds the first radio tube patented by Dr. Lee de Forest in 1907. Other objects (above the tube and clockwise) are: the world´s first practical typewriter, made by Remington in 1874; the first television apparatus developed by Dr. Charles Francis Jenkins in 1925, the first device to transmit and receive an image electronically; Thomas A. Edison´s first mimeograph machine, patented in 1876 and forerunner of all the world´s mimeograph machines and paper stencil duplicating processes; Hugo Gernsback´s 1905 Telimco wireless set, the first home radio marketed in the world; and early iconescope developed by Dr. Vladimir Zworykin in 1940 which transmitted pictures electronically and made possible modern television; and Edison´s first phonograph invented in 1877.
