Hi, my name is Henry Oliver. I own a steel factory in Pittsburgh, Pennsylvania. I came to Minnesota to get iron ore for making steel. I found LOTS OF IRON ORE!!!!! My mining company became a big industry.
Iron ore was found in the Mesabi, Vermilion, and Cuyana Ranges in northern Minnesota. The iron ore was under ground. Above ground it was forested.
That's a lot of air pollution.
Yes, Jimmy, factories in the late 1800s weren't environmentally friendly!!
The Mesabi mines had iron ore close to the surface so miners could work above ground. Huge open pit mines used big machines like electric shovels and trains.
I partnered with John D. Rockefeller so I could make my company even bigger. He transported the iron ore by railroad and ship to the north eastern United States where the factories were.
I also partnered with Andrew Carnegie to make even more money. His factories made the iron ore into steel.
In the early 1900s steel was in high demand for building skyscrapers, cars, and railroads. This helped make cities even bigger and changed the United States in the Industrial Age.
