Magic Lanterns, manufactured by Bausch & Lomb Optical Co. |
Bausch & Lomb was founded in 1853 by the German immigrants
John Jacob Bausch and Henry C. Lomb in Rochester, New York.
 Bausch was a trained
optician and found in Lomb the financier and partner he needed for his small
workshop producing monocles. He promised Lomb that if the business ever grew to where it could support a partner,
Lomb would come into the company.During the American Civil War, the Union blockade caused the price of European horn to rise dramatically and this resulted in a growing demand for the Bausch & Lomb spectacles made from Vulcanite rubber. In 1876, the company began manufacturing microscopes. Later they also produced photographic lenses, spectacle lenses, binoculars and telescopes. From 1892 the company produced optical lenses in cooperation with Zeiss. At the end of the 19th century the product range included projectors, camera lenses and camera diaphragms. Besides lanterns for home use the company manufactured scientific lanterns and biunials of high optical quality, many under the name 'Balopticon'. In 1902, William, the son of the founder, developed a process to create the desired lens shape directly by casting molten glass and this brought significant savings in time and materials. Bausch & Lomb soon became the first American producer of optical-quality glass. In 1971, Bausch & Lomb introduced the first soft contact lenses and is still the largest global provider of eye care products. Today, about 13,000 employees in 36 countries work for the firm. |
