History stuff Paper valley people Bryan Donkin In 1802 the Fourdriniers appointed John Hall of Dartford to construct a working machine based on Roberts drawings and his working model that had been brought to England soon after the Treaty of Amiens brought a pause to hostilities. Progress was at first slow but once Hall's brother-in-law, Bryan Donkin, took charge the project made rapid progress. The Fourdriniers brothers had a new engineeribg works built for Donkin in Bermondsey and leased Frogmore Mill in Apsley, Hemel Hempstead as the site of the new paper mill in 1803, where the improved Robert machine was installed later that year. Donkin continued to refine the machine and a second was installed at Two Waters Mill in 1805. Later in 1822, Donkin adopted T B Crompton's 1821 patent for drying paper continuously over steam heated drying cylinders and the machine that papermakers would recognise as their own - the Fourdrinier -was completed. Donkin is also known for his development of the tin can and involved in Thomas Telford's Caledonian Canal, Marc and Isambard Brunel's Thames Tunnel and Babbage's computer. He was an advisor to government and held in high esteem.
