James Bicheno Francis

Died 18 Sep 1892 at age 77 (born 18 May 1815).British-American engineer who originated scientific methods to test hydraulic machinery and invented the Francis mixed-flow reaction turbine (combining radial- and axial-flow) for low-pressure installations. He emigrated to the U.S. at age 18, and joined the Locks and Canal Co., Lowell, Mass. In 1837, he became its Chief Engineer until retirement. The company owned and operated Lowell's canal system providing waterpower for the textile industry there. Francis designed a more efficient successor to the Boyden turbine, with Uriah A. Boyden of Boston. Being half the size but equal in power, two fit in each wheel pit and doubled power generation.The turbine acted as a hydraulic motor to drive many mill machines through belts and line shafts. He was a founding member of the American Society of Civil Engineers and its president in 1880.«
