Hideo Ozawa was born on May 23, 1930 in Anjo City, Aichi, Japan. After graduating from Nagoya University in 1953 with a degree in physics, he joined Kohfuku Industrial Co., Ltd. (currently Kowa Co., Ltd.) He studied at the Institute of Optics at the University of Rochester, N.Y. from 1957 to 1959, and later lectured on applied optics at Shizuoka University in Japan.
In 1971, Ozawa resigned from Kowa and founded Nidek in Gamagori, Japan. His goal was to link optics and electronics. The company’s first big success came in 1973 when it developed the first Xenon photocoagulator in Japan. In 1982, Nidek introduced the first auto-refractor.
Ozawa passed away of heart failure on June 16, 2009, at a hospital in Gamagori, Japan. He was 79 years old.
