The Gade valley was very much in the forefront of machine papermaking, and in 1803 Henry and Sealy Fourdrinier leased the Frogmore Mill and they installed a early French-designed machine for making paper. However by 1805 they had installed a greatly improved machine, designed by Donkin. This was greatly improved in the following years and the design has been widely used in paper-making.

This informative booklet looks at the history of machine paper-making in the Hemel Hempstead area, and of the people involved in the design and use of the Fourdrinier machine. It has been updated and reissued to celebrate the bi-centenary of the Fourdrinier paper making and to document one aspect of the major museum developments associated with "The Paper Trail" at Apsley.
