This collection includes approximately 40,000 photographs by commercial photographer Ralph Morris, who worked in the Los Angeles area from 1939-1981. His advertising and industrial clients included department stores, restaurants, the automobile and petroleum industries as well as business executives. Also included is the Luckhaus Studio collection of architecture, fashion, the movie industry, sports and street scenes, images which Morris obtained in 1939. View 1: Close-up side view of a lighthouse lamp with multiple glass prisms, or rings; this lamp is most likely a Fresnel lens.; The Fresnel lens, developed in 1822 by French physicist Augustin Fresnel, revolutionized lighthouses in the 1800s. This lens, made up of a collection of multiple glass prisms, bends nearly all the available light into a powerful central magnifying lens. Although the Fresnel lens was invented in 1822, it wasn't used in the U.S. until the 1850s due to the excessive frugality of the then-administrator of the U.S. Lighthouse Establishment administrator, Stephen Pleasonton.
