Print made in 1856 of Henry Cort (1740-1800) who is best known for pioneering the puddling proces for purifying iron. During the Industrial Revolution British iron was not considered to be of inferior quality with the British government importing a significant amount of wrought iron from countries such as Rusia. Cort patented the puddling proces in 1784, a technique which, when combined with rollers, meant that Britian could efficiently purify its own iron for manufacture.
