Among the many treasures in the collections of the Science Museum in London is the complete workshop of the Scottish engineer James Watt (1736–1819), acquired in its entirety from the attic of Watt’s Birmingham home in 1924, where it had been left as an industrial shrine since his death in 1819. Watt is best known for his pioneering work on the steam engine, but the workshop contains very few engine-related items. Instead, it is filled with jars of chemicals, sculpture-copying machines and materials, a profusion of instruments and objects and evidence of Watt’s many diverse projects.
