12 and 8 researched events on one shared scale. Leica 1849–present, Voigtländer 1756–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.
Carl Kellner founded the Optical Institute in Wetzlar in 1849 to make optical instruments. Ernst Leitz joined in 1864, became a partner in 1865, and took sole control after Friedrich Belthle's death in 1869, continuing the firm under his own name. Serial production and international sales made microscopes the business's foundation long before it manufactured the small-format camera now associated with Leica.
The History of the Leica I · Ernst Leitz I - Chronology · Our History
Oskar Barnack joined Leitz in 1911 and developed a small still camera using 35mm cine film horizontally for a 24x36mm frame. The Ur-Leica prototype was completed by 1914. Ernst Leitz II approved series manufacture in 1924, and the Leica I was presented at the Leipzig Spring Fair in 1925. Leica was described by the company as an abbreviation of Leitz Camera. Early production cameras used fixed lenses, chiefly the 50mm f/3.5 optical family associated with Max Berek's work.

The Leica I Model C introduced interchangeable 39mm screw-mount lenses in 1930, initially with each lens adjusted to a particular body. By the end of 1930 or during 1931, Leitz standardized the flange distance; standardized bodies were marked with a zero at the mount and cameras from serial 65,001 onward were made for interchangeable standardized lenses. The Leica II of 1932 integrated a coupled rangefinder, and the Leica III of 1933 added slow speeds. Leitz also maintained separate production books for camera and lens number allocations.

Under National Socialism, Leitz production was redirected toward military optics and used deported forced labor. At the same time, Ernst Leitz II, Elsie Kuhn-Leitz, and company associates assisted persecuted people through training, employment, financial support, and emigration. Frank Dabba Smith's scholarship stresses this combination of humanitarian action, conformist public conduct, military production, and forced labor rather than presenting a simple rescue narrative. Civilian camera production resumed after the war.

Postwar Leitz continued screw-mount cameras and created new optical-glass and lens-development capacity. Ernst Leitz Canada opened in Midland, Ontario, in 1952 and became a major source of cameras and optical designs. The M3, presented in 1954, introduced the Leica M bayonet and combined viewfinder-rangefinder with automatically selected bright frames. The M2 followed in 1957. M-mount lenses and screw-mount lenses with suitable adapters created broad continuity, but early collapsible and specialized designs retained handling or compatibility limits.

The Leicaflex of 1964 opened a 35mm SLR branch with a bayonet whose aperture-information cams changed across later bodies. The Leicaflex SL arrived in 1968. The M5 became the first M camera with an integrated through-the-lens exposure meter. Canadian optical work under Walter Mandler produced influential M and R lenses, including the 50mm f/1 Noctilux design. Leitz opened its Portuguese factory at Vila Nova de Famalicao in 1973 for components and later complete camera assembly.

The electronic Leica R3 of 1976 was developed with Minolta and Copal and assembled in Portugal. Later R cameras and lenses continued the SLR bayonet while adding a stepped R cam and, eventually, ROM contacts. Ernst Leitz Canada developed the M4-2 and continued camera and lens production. The M6 of 1984 returned an exposure meter to the classic-size M body. In 1985 Wild Heerbrugg acquired the Leitz family's company shares, ending direct family control of the larger optical enterprise.

The photography division was restructured and renamed Leica GmbH in 1986, moved from Wetzlar to a purpose-built Solms factory in 1988, and became the camera-focused Leica Camera company. Leica Camera AG separated from the wider Leica Group and completed a Frankfurt stock-market offering in 1996. That year also brought the independently designed R8 and Leica's first digital camera, the stationary S1 scanning system. In 1998 the broader Leica businesses became independent camera, microscopy, and geosystems companies, while the first Digilux compact was based on a Fujifilm platform.

Leica expanded its digital work through cooperation rather than a wholly internal product chain. Collaboration with Panasonic began in 2000 for digital and audiovisual lenses and extended to digital cameras in 2001. The M7 retained film and added an electronically controlled shutter. Facing severe financial pressure during the digital transition, Leica gained an investment from Andreas Kaufmann's ACM-associated group in 2004; Kaufmann became majority owner in 2006.

The M8 of 2006 carried the M mount into digital capture with a smaller-than-full-frame sensor and 6-bit lens coding. The M9 of 2009 became the first full-frame digital M rangefinder. Leica ended production of R cameras and lenses in 2009 without the announced generational successor. Blackstone-advised funds acquired an indirect 44 percent minority stake in 2011 while ACM remained majority shareholder. A 2012 squeeze-out placed all Leica Camera AG shares in Lisa Germany Holding and ended the public listing.

Leica Camera returned its headquarters and major production functions to Wetzlar's new Leitz Park in 2014. The Leica T introduced the short-register electronic mount now called L-mount, and the full-frame SL followed in 2015. In 2018 Leica, Panasonic, and Sigma announced the L-Mount Alliance, allowing each company to develop bodies and lenses around the common specification. Shared mount dimensions did not erase differences in manufacturer, firmware, product support, or sensor format.

Leica Camera continued analog and digital M cameras, the SL and Q families, medium-format S cameras, and sport optics while broadening technology partnerships. The Panasonic relationship was renewed through L-squared collaboration in 2022, and the company expanded mobile imaging with outside electronics makers. Current corporate material identifies Wetzlar and Vila Nova de Famalicao as production sites. Andreas Kaufmann remained identified by Leica as majority shareholder in 2026; the exact current minority percentage was not confirmed in a direct company ownership statement located for this research.

The Voigtländer family workshop developed from Vienna precision instruments into optical work; Peter Wilhelm Friedrich took charge in 1837 and the business used Voigtländer & Sohn from 1839.
Voigtländer manufactured Petzval's mathematically calculated portrait lens and an all-metal daguerreotype camera, then opened the Braunschweig factory in 1849 as demand expanded.
Family succession in 1876 and conversion to a public company in 1898 preceded a wide catalog of photographic lenses, cells, shutters, and camera-related optical products.
