Sarnoff Challenges Scientists of RCA to Make Three Important Inventions B, ► rii;. Gt-ner.il David S.irnoff. Chairman of the Board ot Radio Corporacion of America, speaking at a ceremony in Princeton, N. J., on September 27, com- memoratini; his •i5th anniversarj' in the field of radio. told RCA research scientists that there are three impor- tant inventions he would like to have them make before he reaches his 50th radio anniversary in 1956- Citing contributions RCA scientists already have made to the advance of science and industf)'. General Sarnoff asked them to invent an electronic amplifier of light for television, a television picture recorder, and an electronic air-conditioner for the home. The occasion of the triple challenge to RCA scientists was the dedication of RCA's Princeton laboratories as the "David Sarnoff Research Center," in appreciation of General Sarnoff's "faith in science, penetrating vision, constructive planning and enduring achievements in the fields of radio, television and electronics." "I realize the challenge to your ingenuity in these three new inventions I am asking for," General Sarnoff said, "but I know that you can solve the problems because you have an enviable record of accomplishment in science." The specifications for the three inventions are as follows: First, an electronic amplifier of light that would provide brighter pictures for television which could be projected in the home or theatre on a screen of any desired size. An amplifier of sound gave radio a "loud- speaker" and an amplifier of light would give television a "big-looker." He named it a "Magnalux." "A true photo-amplifier that could produce bigger and brighter pictures in fine detail would greatly advance television in the home." said General Sarnoff. "It is also needed for theatres and industrial purposes. The presently known optical systems cannot accomplish it. We can, of course, enlarge pictures optically, but in the process light is lost and the pictures become dimmer instead of brighter. What is needed is a true amplifier of light itself." Second, a television picture recorder that would record the video signals of television on an inexpensive tape, just as music and speech are now recorded on a phonograph disk or tape. Such recorded television BRIG. GENERAL DAVID SARNOFF "/ would like to ask you now . . . for three presents that I wish you would give me some time between now and my 50th Anniversary in radio." pictures could be reproduced in the home, or theatre, or elsewhere, at any time. He called it a "Videograph." "The television art needs an electronic recorder of television picture signals," said General Sarnoff. "Today when a television program is recorded, the pictures pass from the camera through the major portion of the television system and first reproduce ihe picture on the face of a kinescope. Another and special camera placed in front of the kinescope, photographs the program on motion picture film. But that technique is costly, time- consuming and limited. The pictures pass through all the possible hazards of the television system, and then through all the photographic process with its possible RAD/O AGE 5 'LliWH'. .1 II l< HI
