12 and 14 researched events on one shared scale. Agfa 1867–present, Bausch & Lomb 1853–present.
The axis stretches where either maker has research and collapses where neither does, so a year sits opposite the same year on both. Event counts differ because research depth differs, not because one company did less.
John Jacob Bausch opened a small optical shop in Rochester in 1853. Henry Lomb, another German immigrant, lent him $60 and became his partner. Their early trade centered on imported spectacles and optical goods, but the partnership paired Bausch's practical lens work with Lomb's commercial discipline.

During the Civil War, imported horn for eyeglass frames became scarce. Bausch adapted Charles Goodyear's vulcanite hard rubber to frame production in 1861, giving the firm a scalable American-made product. The business used the Vulcanite Optical Instrument name before returning to Bausch & Lomb Optical Company in 1876.

Paul Mendelssohn Bartholdy and Carl Alexander von Martius established a dye works at Rummelsburg near Berlin in 1867. The enterprise became the Actien-Gesellschaft für Anilin-Fabrication on 21 July 1873. Agfa therefore uses 1867 as its historical origin, while 1873 is the legal incorporation date documented by the Bavarian historical study.
The dye business expanded into photographic chemistry and sensitized materials. Separately, Alexander Heinrich Rietzschel established a Munich optical works in 1896, patented the Linear 4.5 lens in 1898, and introduced the Clack camera in 1900. Bayer acquired 80 percent of Rietzschel in 1921 and the remainder in 1924; Agfa, Bayer's photographic interests, and Rietzschel entered I.G. Farben in 1925.

Microscope production began in the mid-1870s and pushed the Rochester works toward precision optical manufacture. By 1883 the company was making photographic lenses. That sequence matters: photography grew from an established instrument shop with glassworking, mechanical, and measurement skills rather than from a camera cabinetmaker.

Edward Bausch patented a between-the-lens iris diaphragm and shutter in 1887, and commercial shutter manufacture followed. Bausch & Lomb soon supplied both essential sides of the camera's optical package. A surviving circa-1895 stereo camera shows lenses, pneumatic shutter, focus, and movements combined in a complete instrument.

An 1892 agreement made Bausch & Lomb the American producer of important Zeiss anastigmat designs. Planar, Unar, Tessar, and Protar names joined Rochester-made Plastigmat and Universal lenses. The initial contractual era changed during the First World War, yet Bausch & Lomb catalogs continued several design names afterward.

By 1903 the company reported roughly half a million photographic lenses and 550,000 shutters made. Catalogs from 1904, 1920, and 1928 reveal a striking range: still-camera, portrait, process, projection, photomicrographic, telephoto, wide-angle, and motion-picture optics, backed by Rochester optical-glass work.

Agfa established the Wolfen raw-film works in 1909. Under the I.G. Farben division of labor, Wolfen made film and developers, Leverkusen made photographic paper, and Munich made cameras and laboratory equipment. In 1936 Wolfen introduced Agfacolor-Neu, whose anchored color couplers made a commercially practical multilayer process that differed from Agfa's earlier additive color plates.

Motion pictures asked for speed, even coverage, reliable focusing mounts, and repeatable manufacture. The 1928 catalog paired f/3.5 cine Tessars with a 50 mm f/2.7 Ultra Rapid Anastigmat. Later Baltars extended that cinema branch, preparing the ground for the better-documented Super Baltar series.

The Munich works moved from transitional Rietzschel-Agfa products into broad Agfa-branded camera production: the Standard plate camera in 1926, Billy folding roll-film cameras from 1928, Isolar plate cameras in 1929, 6x9 box cameras from 1930, and the Karat 35mm and Isorette/Isolette medium-format folding families from 1937. These families used different formats, fixed-lens packages, shutters, and body-number practices.

Agfa production was redirected toward military, state, and Nazi Party demand. The Munich camera works made aircraft and weapons-related parts and used foreign forced labor from 1942. In September 1944, at the works' request, the SS transferred 500 women from Ravensbrück into a Munich Camera Works subcamp administered through Dachau; later transports followed.

Bausch & Lomb's Metrogon adapted wide-angle optical thinking to aerial mapping. Period technical literature describes lenses selected for large negatives and controlled distortion, including the widely used 6-inch f/6.3 class. A Harvard collection specimen preserves the K-22 association and physical evidence.

The former I.G. Farben Agfa works were separated by occupation zones. Wolfen was dismantled in part, operated as a Soviet reparations enterprise, and became a DDR state enterprise. Munich resumed camera manufacture under Allied controls and material shortages. West German Agfa camera and photofabrication companies were formed as Bayer subsidiaries in 1952-1953, marketed jointly from 1954, and combined in 1957 as Agfa Aktiengesellschaft Leverkusen und München.
The postwar camera range moved from Record and Isolette folders and the Clack/Click transition cameras into the fixed-lens 35mm Silette family, the interchangeable-lens Ambi-Silette, the Agfaflex/Colorflex/Selectaflex reflex branch, and the 1959 Optima programmed-exposure line. The Selectaflex manual documents a camera-specific quick-change lens system from 35mm to 180mm, while the Silette guide explicitly distinguishes the Ambi-Silette bayonet from the fixed lenses of most Silette and Super Silette variants.

Bausch & Lomb worked with 20th Century-Fox on the combination lenses used for CinemaScope photography. The wide-screen process arrived commercially in 1953, and the Academy's technical awards record recognized both organizations for the lens work. The episode put Rochester optics into a highly visible industrial transition.

The Super Baltar cinema family ranged from 20 mm through 9 inches in a 1967 brochure, with faster apertures at the shorter focal lengths. A NASA technical report identifies a 76 mm f/2 Bausch & Lomb Super Baltar in the Ranger camera system, connecting a studio lens line to lunar reconnaissance.

Agfa answered changing amateur markets with the Rapid system from 1963, Agfamatic 126 cameras from 1970, and 110 pocket cameras from 1972-1974. These cassette systems are not interchangeable. Production was increasingly distributed: Coimbra began amateur-camera manufacture in 1974, and Agfa products were also made in India, Brazil, Spain, Hong Kong, and Manila. Supplier responsibility likewise varied, including separately marked shutters and later external manufacturing.
West German Agfa and Belgium's Gevaert formed the Agfa-Gevaert group through a cross-shareholding structure. In the same year, the East German Wolfen enterprise stopped using Agfa for its photographic materials and adopted ORWO after the postwar trademark arrangement with Agfa Leverkusen ended. These were separate corporate and trademark events and do not make ORWO a West German camera line.
The company's photographic achievements remained part of its identity, but eye care increasingly drove the operating business. SofLens contact lenses arrived in 1971, followed by expansion in lens-care, pharmaceutical, and surgical products. By the end of the century, cameras and photographic objectives were legacy fields rather than the corporate center.
The Compact/Optima 935 was the last camera identified by the specialist museum as manufactured at Munich. Agfa's own camera production stopped in 1982 according to the Bavarian corporate history, while the Science Museum Group summarizes the exit as 1983. Agfa-Gevaert then continued to sell amateur equipment made in third countries; the Selectronic name itself covered Munich-built rangefinders and Chinon-produced reflex cameras.
Agfa-Gevaert was listed publicly in 1999. In November 2004 it transferred Consumer Imaging assets, liabilities, and about 2,860 employees to the independent AgfaPhoto GmbH. Agfa's own closing announcement emphasized that AgfaPhoto thereafter operated independently. AgfaPhoto GmbH filed for insolvency on 27 May 2005, ending the brief operating-company continuity created by the divestiture.
Agfa-Gevaert remains a Mortsel-based business-to-business imaging and information-systems group rather than a continuation of the historic Munich consumer-camera factory. Current consumer goods use an AgfaPhoto licensing structure. AgfaPhoto Holding's official imprint states that AgfaPhoto is used under license from Agfa-Gevaert GmbH and that neither Agfa-Gevaert nor AgfaPhoto manufactures, warrants, or supports the licensed products.
Warburg Pincus completed a take-private acquisition in October 2007 in a transaction valued at about $4.5 billion including debt. Valeant then completed its acquisition in August 2013, making the business a subsidiary. These transactions changed ownership and financing, not the historical attribution of Rochester photographic products.

Bausch + Lomb returned to public markets in May 2022 under the BLCO symbol while Bausch Health retained a controlling interest. The offering created a separately traded eye-health company but did not revive photographic-lens production. Present corporate status should therefore be kept distinct from the vintage catalog.

The 2025 annual filing describes a global eye-health company with about 13,000 employees and roughly 400 products, with Bausch Health still holding about 88 percent in February 2026. It also records substantial owned Rochester office, research, and manufacturing space, preserving a real geographic continuity.
