Carl Gustaf Patrik de LavalBorn 9 May 1845; died 2 Feb 1913 at age 67.Swedish scientist, engineer and inventor who pioneered in the development of high-speed turbines. After earning his Ph.D. at age 27, he worked as a technical engineer at a steel mill in his home village. In 1877, he began developing a high-speed centrifugal cream separator, a significant advance in butter-making. He perfected a vacuum milking machine in 1913. About 1882, he began working on steam turbines, and by 1889, he applied for a British patent for an impulse type, with a jet of steam impinging on a set of blades around the periphery of a wheel. His inventive talent was wide, including electric lighting, electrometallurgy, and aerodynamics. During his lifetime, he acquired 92 Swedish patents and founded 37 companies. |
