Sir Francis Pettit Smith (1808-74), inventor of the screw propellor. An enthusiastic builder of model boats as a boy, by 1835 Smith had built a model propelled by a screw, powered by a spring, which he believed would be more efficient than the paddle wheel then universally used by steamships. The following year Smith took out a patent for screw propulsion, and applied his technology to progressively larger vessels. The Admiralty persuaded Smith to build a large ship, the 'Archimedes' (the name is inscribed on the propellor visible in this portrait), but eventually declined to purchase it, leading to the failure of Smith's company. Smith's friends rallied around him, however, and secured him a civil-list pension and the post of director of the Patent Office museum. Smith was knighted in 1871. Fine mezzotint after the portrait by William Boxall now in the Science Museum.
