on the manufacturing side of the business. The firm took yet another name in 1876, "Bausch and Lomb Optical Company," and began manufacturing microscopes. Later that year they exhibited at the Philadelphia Centennial Exposition. The company also produced photographic lenses (1883), spectacle lenses (1889), microtomes (1890), binoculars and telescopes (1893). The firm was incorporated as "Bausch and Lomb Optical Company, Inc.," in 1908, the year Bausch's long-time partner died. Bausch's company did very well during the First World War as the war created a demand for binocular telescopes, range-finders, gunsights, searchlight mirrors, periscopes and torpedo tube sights. The U.S. government became Bausch and Lomb's major customer as the company produced related optical instruments for the armed forces. One of their famous products was Ray-ban sunglasses, until they sold it to the Italian eyewear conglomerate Luxottica. Bausch led his company for more than six decades. He died in 1926 in Rochester, New York. Bausch & Lomb continued to flourish under the leadership of his son Edward Bausch, remaining preeminent in its field. It was named to the Fortune500 list of America's leading companies in 1975.
