This 1936 work, written to commemorate Watt's bicentenary, discusses the man and his achievements in their historical and social context, and is well illustrated. Watt's importance to the history of British engineering and industry owed much to his business partnership with Boulton, which enabled the wider implementation of his ideas.

This 1936 study of the life and work of Watt places his achievements in the context of the Industrial Revolution.
