Mr. Teruo Hiruma, honorary chairman, passed away


It is with great sadness that the Hamamatsu Photonics family announces the passing of our honorary chairman and past President, Mr. Teruo Hiruma, on March 29. He was 91 years old. Affectionately known as “TH,” he led our company from a small local Japanese TV tube producer to a one billion dollar global photonics company. TH had a passion for photonics and was constantly challenging our engineers to build the perfect detector, but he also had a passion for humanity and using light to improve the human condition. He will be deeply missed by the Hamamatsu Photonics family and indeed the photonics community, but we are certain that his vision will continue to inspire Hamamatsu Photonics to use light to make the world a better place.
