Carborundum
1891 After Edward Goodrich Acheson tried to make artificial diamond, he then accidentally developed silicon carbide, also known as carborundum. He formed a company in Monongehela, Pennsylvania called Carborundum to exploit its use as an abrasive.
1895 The company moved to Niagara Falls, NY.
1950 Carborundum bought Canada Sandpapers, Inc., which had developed aluminum oxide stearated paper products, widely used in the automotive trade.
