The optical manager of T. Cooke & Sons of York, makers of astronomical telescopes, attempted to eliminate an optical distortion. In 1893 he designed and patented the revolutionary triplet design. The Cooke Triplet fixed an important design problem. T. Cooke & Sons had no desire to enter the photographic lens business, so they offered the manufacturing rights to Taylor, Taylor & Hobson of Leicester, optical instrument makers. The first Cooke photographic lens was made by them in 1894. The Cooke lens was awarded a medal by the Royal Photographic Society.
