Abstract
September 22, 1856.—The invention for which a patent was granted to Robert F. Mushet on Sept. 22, 1856, was very largely responsible for the immediate success of the Bessemer steel process. By the addition of from one to five per cent of molten spiegeleisen to the iron treated by the Bessemer process, Mushet regulated the supply of carbon and restored the small amount necessary for the production of steel. Mushet received little recognition at the time, and his patent did not run its full course. He was awarded the Bessemer gold medal of the Iron and Steel Institute in 1875.
