Historical Significance: Lenses were part of old stock kept at the ACO dispensing laboratory. William Beecher, a jeweller, decided that he could produce better spectacles than the European imports available in 1833. He formed American Optical Company in 1869. Early in the 20th century the company was producing over 600,000 gold or silver frame mounts per year. Edgar Tillyer was director of research in the 1920s to 1940s and with Anna Glancy developed many of the company's optical products.
