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.
Contrary to some claims, he didn't invent color television. That achievement is credited to John Logie Baird when he demonstrated color television in 1928, three years after his public demonstration of black and white television. Camarena patented both in Mexico and the US the first Trichromatic Sequence Field Frequency in 1939. This trichromatic system served as a partial basis for color televisions and is now used by NASA. At the time of his invention, Mr…
George Lopez is a famous Mexican American comic. Guillermo González Camarena is an inventor who in the early 50s invented the color TV. General Mondragon, who invented the assaults rifle, and made the Mexican army capable of having the first fully automatic weapon in the the world. Octavio Paz, Nobel literature award winner in 1990.
The first color television was seen in 1928, invented by John Logie Baird who had demonstrated the world's first black and white television just three years earlier in London. Commercial color broadcasts began in 1953 in the US for just a few months. It was a commercial failure as the televisions were not compatible with the existing black and white broadcasts of the time. In 1955, a new color system was introduced and has been…
The world's first patent for a color TV was granted to a Mexican inventor, Guillermo Gonzalez Camarena. He was 23 years old in 1940 when he obtained US Patent No. 2,296,022 protecting his invention of a "Trichromatic" system for color television transmissions. Luis Miramontes was the main inventor of the birth control pill. Victor Celorio obtained patents for the technology popularly known as Book On Demand, as well as that of Distributed Printing technology in…
