Son of J. J. Bausch, the founder of Bausch and Lomb Optical Company, Edward Bausch was instrumental in bringing microscopes to production at the firm. He also invented and patented a new type of photographic shutter--the iris diaphragm shutter--which was based on the reaction of the eye's iris to the light.
