What did Guillermo Gonzalez Camarena do after or before he invent the color tv?

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. Guillermo Gonzalez-Camarena was 22 years old.
