Braddock’s first industrial facility, a barrel plant, opened in 1850. The borough was incorporated on June 8, 1867. The town’s industrial economy began in 1873, when Andrew Carnegie built the a Edgar Thomson Steel Works on the historic site of Braddock’s Field in what is now North Braddock, Pennsylvania. This was the first steel mill using the Bessemer process in America. As of 2010, it continues operation as a part of the United States Steel Corporation. This era of the town’s Edgar Thomson Steel Works is well known from the novel Out of This Furnace by Thomas Bell.
