A COMPLETE MEANS OF INSTANTANEOUS PARTICIPATION IN SIGHT AND SOUND TCLE V 1 ■ ^^Hm^H Dr. Lee de Forest, pioneer of yesterday and today. Never once since his invention of the audion (three electrode radio tube) has Dr. de Forest rested upon his laurels. He has steadily continued his ardous work in invention and research in electricity and electronics, and now has nearly 300 patents in the United States and foreign countries. These are in wireless telegraphy, radio telephone, wire telephone, sound-on-film talking pictures, high speed facsimile, picture transmission, television, and radio-therapy for physicians. For the past eleven years he has resided in Los Angeles, following his sensational development in New York of the talking picture film. During this time Dr. de Forest has been engaged in important research in (lie field of television and more recently in that of short wave or radio diathermy, as well as in certain adaptations of radio signalling to the needs of aviation. This latter applies particularly to a terrain altimeter to enable the pilot of an airplane to know at all times his exact height above the earth, or his distance from a mountain side. During the course of his research work in radio diathermy Dr. de forest invented and perfected his "Radio-Glow" method of applying weak high-frequenev currents, by 24 means of an especially designed facial mask, to the face and throat. This is for use in beauty parlors to benefit and improve the complexion by application of short wave high frequency currents to the skin and underlying tissues of the cheeks and throat. This treatment and the apparatus for applying it, which he calls the Relaxor, has after two years of investigation and experimentation been perfected to a degree where the Doctor now feels it is ready to be offered to the public. According to the inventor this method of treatment generates infra-red or heat rays within the tissues, aiding the conduction of dissolved substances into the membranes by heat and molecular vibration of the cells and tissues, keeping the oils and creams spread on the surface of the skin under constant but gentle heat, opening the pores and penetrating dormant cells and tissues. As the name "Relaxor" implies, one is said to experience a feeling of relaxation of tense muscles and nerves, which must be beneliieial during these tense, history making days, as Europe alone does not suffer from this hideous "war of nerves." While the Relaxor is a recent invention in the realm of physical therapy, as early By Duster Evans as 1907 Dr. de Forest gave to the surgical world the "Cold Cautery" or radio knife. He is today actively in charge of all research, design and developmental work at the Lee de Forest Laboratories, where his short wave diathermy apparatus is manufactured and distributed. Physicians are today beginning to realize the benign possibilities of radio-therapy, when properly applied, to the ailments and diseases of mankind. Not only is the machine applied to man — but to his pets as well. Many veterinarians now use short wave diathermy to relieve the suffering of household pets and live stock. As early as 1935 a rather unimpressive fat steer exhibited at the Great Western Livestock Show in Los Angeles stole much of the attention away from the show's champions. That fat steer was the first calf ever treated for pneumonia by short wave radio. It had been included in a carload of stock exhibited by the Hathaway Ranch, of Santa Fe Springs, California, and named "De Forest" in honor of Dr. Lee de Forest. One could go on indefinitely reviewing the wonders which have resulted from the life work of Dr. Lee de Forest. It is impossible to conceive all the benefits springing from his initial invention of the audion amplifier tube. This little tube, once referred to in our courts as "a worthless piece of glass," has given us the present long distance phone, the talking motion picture, and all the pleasures of radio in our homes, to say nothing of the many thousands who are now employed in these great and growing industries; or of the countless human lives saved at sea by the S.O.S. call and the numberless thousands whose pain and suffering have been relieved by his medical diathermy apparatus. I don't believe there is a healthier man in America than Dr. de Forest — every day he takes a long walk and exercises. Many years ago he stopped smoking cigarettes when he realized they could not do him any good. Vacationing in August, he climbed 5,500 feet up to Mt. Black, just to try his legs, lungs and heart, followed by a dash up to Mt. Shasta 14,380 feet. Dr. de Forest has always been a great inspiration to young men who have aspired to make headway in the electronic field, and it was for this purpose that he laid out DeForest's Training which is associated with the Herman A. DeVry Corp., manufacturers of the world's largest line of moving picture sound equipment. Many young men in the army and navy and electrical (Continued on page 26)
