Sir John Isaac Thornycroft (1843–1928) was a British shipbuilder, the founder of the Thornycroft shipbuilding company and member of the Thornycroft family.〔Herbert B. Mason (Editor). (Encyclopaedia of Ships and Shipping. ) London. 1908. pp. 630-631. (Full view ) available from GoogleBooks.〕 ==Biography== He was born in 1843 to Mary Francis and Thomas Thornycroft. Thornycroft worked for a while at Palmers Shipbuilding and Iron Company in Jarrow-on-Tyne before studying for a diploma in engineering at the University of Glasgow. At Glasgow he studied under Lord Kelvin and Professor Macquorn Rankine. He established a shipbuilding yard on the River Thames at Chiswick in 1866. He built his first steam launch when he was 19 years old. In 1876, his first vessel for the Royal Navy was a steam torpedo boat, HMS ''Lightning''. His yard built a steam-powered lorry which led them into the vehicle manufacturing business, the Thornycroft named business lasting until the late 20th century. Thornycroft worked on means of aiding hull lubrication by air which also led him to the hydrofoil. This led him to develop stepped chine hulls which used for 55 ft British Coastal Motor Boats during the war gave them speeds of up to 40 knots.〔(1908 Thornycroft Model at The Hovercraft Museum ) at www.hovercraft-museum.org〕 In 1904, he transferred larger shipbuilding activities to Southampton. In 1908 he also set up the Hampton Launch Works on Platts Eyot, an island on the Thames at Hampton, Middlesex. He died in 1928.〔Sir John Isaac Thornycroft - 1843-1928. Obituary notice.
