Photographic company founded in London in 1854 by George Swann Nottage (1822-1885) and Howard John Kennard (1839-1896). It went through numerous name changes but is usually referred to, and continues to be referred to, as the London Stereoscopic Company (LSC). From about 1889 to 1912, the company was located at 106 and 108 Regent St, London. The company published photographs, with William England and Thomas Richard Williams as the main photographers, and was also involved in the manufacture of photographic equipment. The company dissolved in 1922.

Not to be confused with the London Stereoscopic Company established by rock guitarist Brian May in 2005.

A. Kershaw & Son, manufacturers of scientific and electrical instruments, was founded in 1888 in Leeds by Abram Kershaw (1861-1929). The company began producing photographic equipment in the early 1900s. In 1904, Abraham registered two patents: one for measuring the speed of photographic shutters and another for improvements to cameras, including a folding mirror mechanism, thus making the birth of the single-lens reflex camera. This mechanism was manufactured for a range of companies, including the London Stereoscopic Company's Artist Reflex camera.

After the First World War, A. Kershaw & Son established two additional subsidiary marketing companies, one of which was the Kershaw Optical Co. This subsidiary partnered with Marion and Co. to open sales depots in major cities across the United Kingdom and to build a network of sales outlets for their photographic and optical equipment.

In 1921, Kershaw Optical Co., along with the parent company A. Kershaw & Son, joined five other firms to form the Amalgamated Photographic Manufacturers (APM). As an independent entity, A. Kershaw & Son ceased to exist.

The Kershaw brand departed the APM group in 1929 and continued camera production under the name Soho Ltd. During the Second World War, the company produced military optics such as gunsights and binoculars.

Around 1947, Kershaw was taken over by British Optical and Precision Engineers Limited (BOPE), a subsidiary of the Rank Organisation. Thereafter, cinema projection equipment became its main output. In the early 1960s, the manufacturing plant began to be sold off and production declined steadily. By 1981, only a caretaker remained employed. The Rank Organisation's Leeds operations were finally vacated around 1983.

Marion & Company, usually styled Marion & Co., was a London-based photographic firm with roots in early 19th century France. Its origins trace back to around 1835, when Claude Mames Augustin Marion established a stationery business in Paris. The company was known as Auguste and Augustin Marion interchangeably. Around 1842, at the dawn of the photographic age, Marion opened a London branch of Marion & Co., initially importing and selling French stationery.

By 1854, with premises on Regent Street, Marion & Co. had begun to stock papers designed for photographic use, such as salted and albumen types, alongside traditional stationery. In 1866, the company opened a warehouse and showroom at Soho Square. The following year, Claude Marion retired as head of Auguste Marion & Co. and a new company, Marion & Co., was formed under the control of three partners: Auguste Leon Marion, Henry Edward Géry, and George Bishop.

During the 1880s, Marion & Co. expanded into manufacturing photographic equipment and materials, including cameras and studio apparatus. In 1886, it opened a dedicated factory in Southgate, Middlesex, producing photographic paper, plates, and later, roll-film cartridges. As photography gained popularity among the general public, Marion & Co. increasingly targeted amateur photographers. The publication of Marion's practical guide to photography (1884) catered to this growing market.

By the late 1890s, the company was managed by Auguste Leon Marion, Henri Louis Guibout, George Bishop, Frank Bishop, and John Pattinson Kirk. The partnership was dissolved in 1901, and the business continued as a limited company. In 1921, Marion & Co. Limited was absorbed, along with six other companies, into Amalgamated Photographic Materials (APM), ending its existence as an independent entity. In 1929, AGM split off the photographic product lines of Marion, Paget and Rajar divisions into a new entity called Amalgamated Photographic Equipment Materials (APeM). Shortly thereafter, ApeM was incorporated into the Ilford group.
