LABORATORY SERIES. No.12. James Watt’s attic workshop. Locked and untouched after his death in 1819, the workshop was described by biographer JP Muirhead as an industrial shrine to the Steam Engineer, “where no profane hand had been allowed to violate the sanctities of the magical retreat.” Moved piece by piece from his home in Heathfield, the 20 ft x 15 ft workshop, which contains over 8,430 objects, now sits in its preserved state in the Science Museum in London.
