Excerpts from the Wikipedia article: <\/span>

Guillermo Gonz\u00e1lez Camarena<\/b> (February 17, 1917 \u2013 April 18, 1965) (aged 48), was a Mexican <\/span>engineer<\/a> who was the inventor of a color-wheel type of <\/span>color television<\/a>, and who also introduced color television to <\/span>Mexico<\/a>.<\/span><\/span> <\/p>\n

Born in Guadalajara<\/a> in 1917, his family moved to Mexico City<\/a> when Guillermo was almost 2 years old. As a boy he made electrically propelled toys, and at the age of twelve built his first Amateur radio<\/a>.<\/span><\/p>\n

In 1930 he graduated <\/span>from the School of Mechanical and Electrical Engineers (ESIME) at the National Polytechnic Institute (IPN) with an engineering degree<\/a>; he obtained his first radio license two years<\/span><\/span> later.<\/span><\/span> <\/p>\n

He was also an avid stargazer; he built his own telescope<\/a> and became a regular member of the Astronomical Society of Mexico.<\/span><\/p>\n

Gonz\u00e1lez Camarena invented the “Chromoscopic adapter for television equipment”, an early color television transmission system. A U.S. patent application (2,296,019) states:<\/span><\/p>\n\n\n\n
\u201c<\/span><\/td>\nMy invention relates to the transmission and reception of colored pictures or images by wire or wireless…<\/span><\/td>\n\u201d<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

On August 31, 1946, Gonz\u00e1lez Camarena sent his first color transmission from his lab in the offices of The Mexican League of Radio Experiments, at Lucerna St. #1, in <\/span>Mexico City<\/a>. The video signal was transmitted at a frequency of 115 MHz. and the audio in the 40 meter band.<\/span><\/p>\n

He died in a car accident in <\/span>Puebla<\/a> on April 18, 1965, returning from inspecting a <\/span>television transmitter<\/a> in Las Lajas, <\/span>Veracruz<\/a>.<\/span><\/span> <\/p>\n

A field-sequential color<\/a> television system similar to his Tricolor system was used in NASA<\/a>‘s Voyager mission in 1979, to take pictures and video of Jupiter.[<\/span>1]<\/span><\/a><\/sup><\/span><\/p>\n

In 1995, a Mexican science research and technology group created La Fundaci\u00f3n Guillermo Gonz\u00e1lez Camarena (The Guillermo Gonz\u00e1lez Camarena Foundation)<\/i>, which benefits creative and talented inventors in Mexico.<\/span><\/p>\n

At the same time, the National Polytechnic Institute<\/a> began construction on the Centro de Propiedad Intelectual “Guillermo Gonzalez Camarena” (Guillermo Gonz\u00e1lez Camarena Intellectual Property Center)<\/i>.<\/span><\/p>\n
