In 1888, Youngstown industrialists George D. Wick and James A. Campbell organized the Mahoning Valley Iron Company, with Wick as president. Charles Dayton Arms, Wicks brother in law and also an iron entrepreneur, was brought in as president. Five years later, the two men resigned from the firm when it was taken over by the Republic Iron and Steel Company, and their next project would come in response to major changes that occurred in the community's industrial sector. Youngstown's industrial leaders began to convert from iron to steel manufacturing at the turn of the century, a period that also saw a wave of consolidations that placed much of the community's industry in the hands of national corporations. To the rising concern of many area industrialists, U.S. Steel, shortly after its establishment in 1901, absorbed Youngstown's premier steel producer, the National Steel Corporation.
