Ohio played a key role in the development of the modern steel industry. Andrew Carnegie, one of the most famous industrialists of the late 19th and early 20th centuries, started his career in the steel industry in Pittsburgh, Pennsylvania, but his first major investment was in a steel mill in Braddock, Ohio.
