Thomas, Sidney Gilchrist

 

Born Apr. 16, 1850, in Canonbury, near London; died Feb. 1,1885, in Paris. English metallurgist.

Thomas studied the humanities in college. While working as a clerk in a London court, he attended evening courses at the Royal School of Mines. In 1878, together with his cousin P. Gilchrist, he solved the problem of dephosphorizing high-phosphorus pig iron in the Bessemer converter by developing the Thomas-Gilchrist process. Between 1877 and 1882, Thomas took out a number of patents for making steel by this method. He proposed that the high-phosphorus slag produced by his process be used as fertilizer.
