Show Invented Halftone The process of reproducing the tones of a photograph by means of dotted or checkered spots was invented in-vented in 1880 by Stephen Henry Horgan, an American photographer, photogra-pher, says Pathfinder. The first halftone ever printed appeared in the New York Daily Graphic in 1880. But Horgan's process was not immediately accepted. In fact, he was fired as art director of the New York Herald in 1893 when he suggested using halftones to publisher pub-lisher James Gordon Bennett. The values of half-tones are achieved by interposing a screen between the original photograph and the plate to be etched. Mr. Horgan also experimented with transmitting photographs by wire, inventing a method in 1879. The inventor died in Orange, N. J., last month, aged 87. |
