1877-1880s
Josef Rodenstock founded the optical business in Würzburg in 1877; it relocated to Munich during the 1880s and developed into an integrated optical manufacturer.
Rodenstock and Taylor Hobson / Cooke
8 and 12 researched events on one shared scale. Rodenstock 1877–2013, Taylor Hobson / Cooke 1886–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.
1870s
1880s
Leicester lens workshop founded
1886-1893
William and Thomas Smithies Taylor opened a Leicester lensmaking business in 1886, and William Smithies Hobson joined in 1887. The partnership became Taylor, Taylor & Hobson, combining optical manufacture with an expanding commercial operation before the Cooke license defined its photographic reputation.
1890s
Cooke Triplet enters production
1893-1897
Harold Dennis Taylor of T. Cooke & Sons patented the three-element anastigmat in 1893 and arranged for Taylor, Taylor & Hobson to manufacture it in Leicester under the Cooke name. The first photographic lenses followed in 1894, establishing a brand-and-maker relationship that would last more than a century.
Cooke still catalog expands
1897-1913
Cooke catalogs grew into a system of portrait, general-purpose, high-speed, process, wide-angle, convertible, and telephoto series. Barrels, sunk mounts, shutters, focusing mounts, and matched extension cells let the Leicester works serve hand cameras, reflex bodies, studios, and large commercial plate cameras.

1910s
1912
A period catalog documents a mature photographic range built around Eurynar double anastigmats, Pantogonal extreme wide-angle lenses, and telephoto combinations.
Aviar serves aerial reconnaissance
1914-1919
War work brought aerial reconnaissance, rangefinder, and military-optical demands. The four-element Aviar answered the need for fast, reliable definition from aircraft and later moved into civilian photography, while the firm's precision manufacturing expanded under conditions that cut Britain off from German optical supply.
1920s
Opic opens fast cine era
1920-1929
Horace W. Lee's Series O Opic combined a six-element double-Gauss-derived design with an f/2 aperture. Alongside Kinic cinematograph lenses and expedition telephotos, it gave Taylor, Taylor & Hobson the optical foundation for sound-era cinema just as the company shortened its name to Taylor Hobson.

1930s
early 1930s
Rodenstock marketed Clarovid folders and the Imagon soft-focus system; museum evidence shows complete cameras could combine purchased bodies with Rodenstock lenses and Deckel shutters.

Speed Panchro reaches Hollywood
1930-1939
Bell & Howell took control in 1930 and distributed Cooke cine lenses in the United States. Speed Panchros expanded across the focal range needed by 35mm studios, while Lee's inverse-telephoto design provided the long back focus demanded by three-strip Technicolor cameras and helped the Leicester lenses become studio standards.

1940s
Rank ownership and lens coating
1945-1953
Rank acquired Taylor Hobson in the mid-1940s, and factory coating became regular practice in 1947. Gordon Cook joined in 1948 and began revising the Speed Panchro line with new glass and larger coverage, carrying prewar designs into a postwar cinema industry moving toward wider screens and higher contrast.

Kinetal and Varotal systems grow
1953-1970
Series II and III Speed Panchros, Kinetals for 16mm, Telepanchros for long shots, anamorphic research, and purpose-built television zooms broadened Taylor Hobson's reach. Gordon Cook's Varotal III, V, and XIV addressed live broadcast with servo control, long zoom ratios, and increasingly sealed optical mechanics.

The dated dealer notebook lists Sironar, Grandagon, Heligon, Rotelar, Ysarex, Apo-Ronar, Imagon, and Rodagon configurations.
1970s
Cine zooms become a specialty
1971-1995
The 20-100mm Varotal of 1971 established the mechanical pattern for later Cooke cinema zooms. Varokinetal, Super Cine Varotal, Varopanchro, wide-angle Varotal, and Cinetal models served 16mm, Super 16, and 35mm production, while work on S4 primes prepared the lens branch for a new corporate life.
1980s
1981-1982
Catalogs reorganized the large-format program around Sironar-N, Grandagon, Apo-Ronar, Imagon, Geronar, and Geronar-WA, alongside a broad enlarging-lens range.

1990s
1990s-2000
The precision-optics branch was separated from the ophthalmic company; LINOS acquired Rodenstock Präzisionsoptik in 2000.
Cooke lens branch separates
1998
Les Zellan led the purchase of Taylor Hobson's optical division and formed Cooke Optics Limited. The transaction created a new legal company while retaining Leicester personnel, machines, designs, and practical manufacturing knowledge from the historic lens branch; Taylor Hobson continued along its metrology path.

Cooke continues Leicester manufacture
1998–present
Cooke Optics Limited remains an active Leicester manufacturer of cinematography lenses. Its present factory belongs to a company incorporated in 1998, yet its workforce, tooling, design archive, and product lineage connect directly to the Taylor Hobson optical division and the Cooke name first placed on Leicester-made lenses in 1894.

2000s
Taylor Hobson joins AMETEK
2004–present
AMETEK acquired Taylor Hobson in 2004. The Taylor Hobson name now identifies an active precision-metrology manufacturer whose surface and form instruments grew from the measurement problems of lensmaking, rather than the current producer of Cooke-branded photographic and cinematographic lenses.
2006-2013
The photographic branch passed through Qioptiq, which Excelitas acquired in 2013.
