Question

How did Carnegie made his money

I know it was the steel Industry but when I found this info. I'm having a hard time creating it in my own words. It's not like I'm going to copy this but how can I make it into 2-3 sentence.

info:
Carnegie's early jobs practically mapped out the technological emergence of 19th-century America. He was a bobbin boy in a textile factory, a telegraph operator, an engine tender. Then he worked with railroads and with oil wells. But when he was 38 he started the Keystone Iron Works, and he stayed with that until 1901. By then Keystone Iron had become U.S. Steel, and Andrew Carnegie had become one of the wealthiest men on the planet.
