Kenjiro Takayanagi (高柳 健次郎 Takayanagi Kenjirō, January 20, 1899 in Hamamatsu, Shizuoka – July 23, 1990 in Yokosuka) was a professor of faculty of engineering at Shizuoka University  and a pioneer in the development of television. He built the world’s first all-electronic television receiver, and is referred to as “the father of Japanese television”. In 1925, Prof. Takayanagi began research on television and developed the first “all-electronic” television system to display the received signal by using a cathode ray tube . On December 25, 1926, he successfully demonstrated his system at Hamamatsu Industrial High School ( is now the Faculty of Engineering at Shizuoka University). The first picture he transmitted was of the Japanese katakana character 「イ」.
