In what town in Pennsylvania was Andrew Carnegie's business located?

Answer 1

Andrew Carnegie was known for his business in the Steel Industry. By buying out other companies in the industry, he created what is known as a vertical monopoly, where he controls an industry through the whole process. i.e. He owned companies that mined the materials, transported them, processed them, and forged the steel for the final product. He used the City of Pittsburgh as the location for his steel mills, because of the ease of transportation by means of the three rivers. This is also why Pittsburgh is referred to as the Steel City - steel was the main industry of the city.
