In 1925, Takayanagi began research on television after reading about the new technology in a French magazine. He developed a system similar to that of
John Logie Baird, using a
Nipkow disk to scan the subject and generate
electrical signals. Unlike Baird's display method, Takayanagi used a
cathode ray tube to display the received signal, thereby demonstrating electronic image reception. On December 25, 1926, Takayanagi successfully demonstrated his system at Hamamatsu Industrial High School, where he was teaching at the time (the school is now the Faculty of Engineering at
Shizuoka University). The first picture he transmitted was of the Japanese
katakana character
イ made up of 40
scan lines. In the late 1950s, he developed a two-head,
helical scan video tape recorder. He was also involved in the development of color television. In 1984, he created his own foundation for the study of electronics. ==Honours==
