Sinclair, Henry Harbinson, 1858-1914.

Henry Harbinson Sinclair was a hydro-electrical engineer and entrepreneur active in California from 1887 until 1914. Born December 22, 1858, Sinclair was a native of Brooklyn, New York. At 15, he went to sea, and first visited California in 1874 after a voyage around Cape Horn. He arrived in Redlands, in San Bernardino County's citrus-growing region, in 1887. In 1892, Sinclair, with a number of other investors and businessmen, created the Redlands Electric Light and Power Company, which within a few years had created the world's first three-phase electrical system. Sinclair was a director of both the California Power Co. and Southern California Edison and was at one time the general manager of the Edison Electric Co. During the closing years of his life, Sinclair lived in Pasadena and was on the Board of Directors of the Tournament of Roses. He faced repeated health problems after 1900 and died in September of 1914.
