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 Edgar Thomson Steel Works on the historic site of Braddock's Field in what is now North Braddock, Pennsylvania. This was one of the first American steel mills which used the Bessemer process. As of 2010, it continues operation as a part of the United States Steel Corporation. This era of the town's history is depicted in Thomas Bell's novel "Out of This Furnace".
