What had Guillermo Camarena to do with color television?

Guillermo Gonzalez Camarena (1917-1965), is a Mexican national from Guadalajara Jalisco. His project was rejected by the Mexican authorities and had to go to the United States.

In 1934 he made his first TV when he was 17 years old, later he patented his color TV in Mexico and the US. He holds patents to various color television systems from 1940, 1942, 1960 and 1962. In 1940 at the age of 22, Guillermo Gonzalez Camarena obtained US Patent #2,296,022 for his Trichromatic system used for color television transmissions.

In August 31, 1946 he sent his first color transmition from his lab in the offices of The Mexican League of Radio Experiments in Lucerna St. #1, in Mexico City. The video signal was transmited in 115 MHz. and the audio in a band of 40 meters. RCA claims they did it in 1946 but Camarena's patent has an earlier month. Also, there are previous attempts or designs.

Guillermo Camarena's work was impressive but some wrongly attribute the first color television to Camarena. However, Scotsman John Logie Baird sent images by a mechanical colour television in 1928, before his electro-mechanical black-and-red system was adopted by the BBC in 1929. This is the first demonstration of color television and precedes Camarena's patents by twelve years.

In 1943, he suggested to the Hankey Postwar TV Commitee that postwar TV should be 1000 lines 3d, color and Black-and-White compatible. The commitee did not think this was possible, but Baird made it work before his death in 1946, a week after he demonstrated the above system, which was the first fully electronic color television in the world. He sent famous actors and moving cartoons through the air in colour and his images would have been simlar to the HDTV of today. If you search for "John Logie Baird Telechrome" you will be able to see the images reproduced. His system was almost flat screen.
