Armenian engineer, first inventor of color television and televideo. Born in Baku to a family of petroleum experts on Feb. 5. During 1899-1904 studied in Munich, Zurich and later in Berlin universities.In 1905 he presented his theory about the conversion of pictues into electrical impulses, according to which he theorized that the amplitude of electronic pictures were dependent on the clarity of the dots. HFor his invention and application of " The direction and reproductivity of electronic pictures" in 1907 he applied for a patent at the Imperial office at Berlin and was granted patent # 197443 in which he had proposed the transmissibility of pictures created by oscillography. Another patent #197183 was granted for his work on two color teletransmission. In 1907 he succeeded to transmit color pictures to a distance of 600KM. He moved to Petersburg and in 1921 at the 8th convetion of the Pan Russian electrical engineers he presented his paper about the feasibility of electronically transmitting of pictures over distances and in 1930 he actually succeeded to transmit pictures from Moscow to Leningrad. In 1925 he presented his theory about color transmissions (separation of colors at the transmission site and re assembling at the receiving end) and successfully demonstrated transmission in three colors. The latter theory was first applied in London in 1928, and in 1945 CBS in the US accepted the concept and used it until 1953.

H. Adamian died in Leningrad. His ashes were transferred to Erevan in 1970.
