Rebecca Lukens became America’s first female industrialist when she owned and operated multiple businesses at one time: Brandywine Iron Works & Nail Factory, a farm, a store, a warehouse, and a freight agency. From 1919 through the 1950s, Lukens Steel Company operated the world’s widest rolling mill, standing at 206 inches wide and still operating today. The site today, owned by ArcelorMittal, is the longest continuously operating iron and steel site in the United States.
