S. Baring-Gould, Devonshire Characters and Strange Events
“ Richard Savery was the father of Thomas, who was born, according to Smiles, at Shilston about the year 1650. He was educated to the profession of a military engineer, and in course of time reached the rank of trench-master. The pursuit of his profession, as well as his natural disposition, led Savery to study mechanics, and he spent all his spare time in executing mechanical contrivances of various sorts. One of the first of these was a paddle-boat worked by men turning a crank. He spent £200 on this, and built a small yacht on the Thames to exhibit its utility. ”
