Charles Francis Brush (March 17, 1849 – June 15, 1929) was a U.S. inventor, entrepreneur and philanthropist.
After working in various partnerships, and in different fields (including iron ore sales and chemistry), Brush went on to build his 'dynamo' (an electrical generator), which became the central power system for his arc light.
In 1879 he formed the Anglo-American Brush Electric Light Corporation in Lambeth, London, England. This company eventually moved to Loughborough England and became Brush Electrical Machines Ltd.
In 1880, he established the Brush Electric Company, which eventually merged to become part of General Electric in 1891. In 1882 the Brush Electric Company supplied generating equipment for a hydroelectric power plant at St. Anthony Falls in Minneapolis, which was the first to generate electricity from water power in the United States.
Between 1910 and 1929 he wrote several papers on his version of a kinetic theory of gravitation, based on some sort of electromagnetic waves. He died on June 15, 1929.
