Kenjiro Takayanagi (高柳 健次郎, Takayanagi Kenjirō, January 20,
1899 in Hamamatsu, Shizuoka – July 23, 1990 in Yokosuka) was a
Japanese engineer and a pioneer in the development of television.
Although he failed to gain much recognition in the West, he built the
world's first all-electronic television receiver, and is referred to
as "the father of Japanese television".

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. But unlike Baird, Takayanagi took the
important step of using a cathode ray tube to display the received
signal, thereby developing the first "all-electronic" television set.
On December 25, 1926, Takayanagi successfully demonstrated his system
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 made up of 40 scan lines. This was several months before
Philo T. Farnsworth
Philo T. Farnsworth demonstrated his first fully electronic system in
San Francisco on September 7, 1927, which did not require a Nipkow
disk. (See History of television.)
In subsequent years, Takayanagi continued to play a key role in the
development of television at
NHK (the Japan Broadcasting Corporation)
and then at
JVC (Victor Company of Japan), where he eventually became
vice president. He was also involved in the development of color
television and video tape recorders. He died of pneumonia in
1990 at the age of 91.
