RAY OF SUNLIGHT LED 10 WIRELESS Marconi’s Discovery Accidental —Inventor Looks Into Future London, July 12 (UP)—A ray of | sunshine chanced to strike a sma:l mirror held in the hands of a youth of genius some 40 years ago in Italy As a result of this seemingly com- mon occurrence, ten years later and for the first time, a ship at sea in distress was enabled to summon help with an 8§ O S, The story was told to the United Press correspondent by a quiet, modest and unassuming Italian gen- tleman whose name is now synon- ym-us with wireless. It was during an exclusive interview in which after predicting almost fantastic de- velopment in the science of wire- less telegraphy, including the future Wireless transmission of light, pow- er and heat, moving pictures and television, he, Senator Guglielmo Marconi, described how he came to discover wireless telegraphy: “It was really quite simple,”” he commenced as though, instead of describing one of the greatest in- ventions in the history of th2 world he were relating the story “why a chicken crosses the road.” “Like almost every boy that ever lived,” he continued simply. "I used to catch rays of sunshine on a mir- ror and. he paused and smiled significantly, then added, “well, you know as well as I do all the fun that one can have with a mirror and a little sunshine, don’t you? “But to me there was something more in it than sheer amusement. To me this reflection of light waves in the form of the sun's rays, meant an ideal way of trans- mitting signals to my friends. I put.the idea into practice. Soon I was able to ‘converse’ with my friends at a distance by means of flashing sun rays. A Cloudy Day's Liffect “But one day clouds hid the sun from view and as a result my sig- nalling _activities were temporarily interrupted. Indeed I d then for the first time that this method of communication was imperfect. And from that time on I set my mind upon the problem of discov- ering a way to make up for defects of the system. “Inasmuch as clouds or darkness prohibited the transmission of light waves emitted by the sun, I de- ctded to use Hertzian waves whici are available at all times, night or day, whether the sun shines or not.” “That, as you probably know,” he added simply, “is what resulte in the invention of wireless telegra- the P The senator spoke in perfect English. His tone is gentle. His manner quiet. Reclining comfort- ably in his armchair in a vast of- fice at Marconi House in the Strand, he might have almost been mistaken for a college professor lecturing to a class of history. Only when the correspondent asked him what future he visual- ized for his invention, did the Sea- ator slightly relinquish his calm manner and wax enthusiastic: Possibilities of Wircless “Wireless has a very great fu- ture indeed,” he commenced, and then began to enumerate its possi- bilities: “I should say that the in the development of will be the transmission of moving pictures into peoples’ homes. I be- live that we shall be ly to accomplish this within the next vear or two. Then, too, wireless television will ~ome. This, how- ever, is still far off, I think. But it is improving and I believe that sooner or later the people on either side of the Atlantic ocean will be able to witness televisioned public ceremonies. For instance, th swearing in of a president of the United States in Washington could be seen in Europe from armchairs in private homes or theate Peo- ple in the United States could, on the other hand. witness such cere- monies as the opening of parlia- ment here, “I also believe that in the far distant future, it may be possibl: to transmit heat, light and power by wireless. And at a still more distant time, no doubt, we shall succeed in moving objects at a dis- tance, for instance, airplanes, ships or locomotives. \“Then too I believe that future zenerations will see wireless tele- phones in general use. At-the same time, however, 1 do not visualize great numbers of them. I cannot, next s wirele: NEW BRITAIN DATLY HERALD, FRIDAY, JULY 12, 1929. for instance, imagine that there will ever be say 50,000 individual wireless telephone subscribers 1n London conversing simultaneously to 50,000 individual subscribers in New York or vice versa.

Recent Discovery “But the possibilities of the de-| velopments of wireless telephoning | were considerably increased by our| latest discovery, the superimposing of telephone and telegraph serv- ices. By means of this we c transmit simultaneously over t same circuit, one or more tele- graphic messages and a tel conversation. This, of cou duces operating costs and at the same time en obtain the utmost use of available ether space. Asked whether he would ever succeed in making wireless transmission absolutely secret, the Senator declared that already, owing to the (about 100 words per minute) at which messages were transmitted at the present time, unauthorized | persons received only a “formid- able jumble of sounds” which was quite unintelligible. Amateurs, he explained further, would be pre- vented from installing the proper apparatus enabling them to dise tangle the “jumble.” (1) On ac count of the prohibitive cost of th apparatus required.
