The National Carbon Company was a dominant American manufacturer of batteries and lighting products in the early 20th century. It was founded in 1886 by the former Brush Electric Company executive W. H. Lawrence, in association with Myron T. Herrick, James Parmelee, and Webb Hayes, son of U.S. President Rutherford B. Hayes, in Cleveland, Ohio.[1] In 1890, National Carbon merged with Thomson-Houston, Standard Carbon, and Faraday Carbon. In 1906 it invested in what became the Eveready Battery Company, which it purchased in 1914. National Carbon was acquired in 1917 by Union Carbide.
