biography

Born in Hamamatsu in 1899 , Takayanagi Kenjirō was a graduate of Tokyo Tech with a doctorate and began research into image transmission possibilities in 1925. At first he developed a system similar to John Logie Baird's , which scanned an object with a Nipkow disk and converted its image into electrical signals. In 1926 he presented the first Japanese black-and-white television at the Hamamatsu Higher Technical School, a forerunner to Shizuoka University . He succeeded in the first electronic transmission of images with a cathode ray tube on the transmitter and receiver side. He first transmitted the katakana イ with the help of a Braun tube . That was a few months before Philo Farnsworth demonstrated his first fully electronic television on September 7, 1927 in San Francisco that did not need a Nipkow disk.

Later, Takayanagi succeeded in the first electronic transmission of a human face. He worked on the development of Nippon Hōso Kyōkai and later JVC , which he led at times as Vice President. He was also involved in the development of color television and video cassettes.

In 1980 Takayanagi Kenjirō was named Bunka Kōrōsha, a person with special cultural merits , and was awarded the Cultural Order in 1981. In 1989 he was awarded the Order of the Holy Treasure .

He died of pneumonia in 1990 .
