Hovhannes Abgari Adamian (5 February 1879, Baku - 12 September 1932, Leningrad) was an Armenian and Soviet engineer, an author of more than 20 inventions. The first experimental color television was shown in London in 1928 based on Adamian's tricolor principle, and he is recognized as one of the founders of color television.
