PICTURES BY WIRELESS

"FROM ANY PLACE ON EARTH." Several years ago a German scientist, Professor Korn, invented a device for the telegraphic transmission of pictures, which required costly, complicated, and very fine apparatus. Now a.young Dane, Mr. Th. Andersen, a watchmaker, has invented a method by which he is ab'.e to.transmit'pictures by the ordinary telc*ra'pli wire or wirelessly for any distance. Mr. Andersen stated: "By investigating the previous attempts at the telegraphic I transmission of pictures I found out the difficulties that had to be overcome, and I approached tho problem from a new direction. I chose a system of special ; signals which can be transmitted with a greater and moro uniform power, and in such a way that they can be sent by means of the apparatus used for transmitting ordinary telegrams. '1 can transmit piotures between any two stations on earth by wire or wireless, and the invention, I shunld say,, will be of importance, first and foremost, to the Press, it being possible to transmit the picture of a person or on event anywhere in the world Just as quickly as an ordinary telegram." Mr. Andersen asked the Danish telegraph Department for permission to demonstrate the invention by using two ot the State's wireless stations. His request was granted, and the picture of a young woman was transmitted from the wireless station at Bleavandshuk (on the west coast of Jutland) to the wireless station at Lyngby, near Copenhagen. Mr. Andersen declares that the transmission of the picture required the same time as the transmission of an ordinary message of 100 words, and that it is the first picture transmitted by wireless. A picture of President Wilson was transmitted over a'short distance during the trial period before Mr. Andersen mado his invention public. Danish experts who have examined tho invention declare that the apparatus required is very simple in construction, and therefore very cheap and easy to use. Practice in sending and receiving the pictures is declared to be very easily aoquired. . ■Experts add that, with further development, it will be possiblo with great accuracy and without great expense to transmit even very complicated pictures, reproducing the various colours which they may contain. In 1910 Mr. T. Thorno Balcor transmitted pictures over the wires from Manchester to London, and in April of that year he announced tflat he had succeeded in adapting his system to the transmission of pictures by wireless. Fifteen years ago the "Daily Mail" published reproductions of pictures transmitted over the telegraph wires between Paris and Rouen by Professor Korn, of Munich, and in 1909 hy this process pictures wore being transmitted regularly from Paris to London and from Manchester to London.
