Hamamatsu Information Book

Horiuchi Heihachirō was the founder of Hamamatsu Photonics K.K.

 

He promptly decided to enroll in Hamamatsu Kōtō Kōgyō Gakkō (present Shizuoka University) when he learned that Takanayagi Kenjirō was undertaking the study on the television there. This was led by his interest in light ever since he learned in school that the light emitted from the North Star takes eight hundred years to reach the earth. He worked on the study under Takayanagi.

However, WWII interrupted them. He established Hamamatsu Terebi (present Hamamatsu Photonics) to continue his research and developed the photomultiplier tube, a photosensor that converts weak lights to strong electronic signals, in 1953.
