Andrew Carnegie was a Scottish immigrant. Born poor, he came to America at the age of twelve. He has a true rags-to-riches story. Carnegie started at a train company working common jobs and worked his way up.
As Carnegie moved up, he began investing in companies. He eventually wound up in the steel business where he made his fortune. By the time of his death he was worth $6,107,o20,231 in modern currency. He was the Bill Gates of his time.
With most of the South's train tracks being destroyed in the Civil War; this led steel manufacturers like Andrew Carnegie to make a fortune. Steel was also needed for the expansion westward.
By the time of his death in 1919, Carnegie donated $4,749,904,624 in modern currency. Carnegie made money in by investing in oil, iron, railroads, and telegraphs as well; but his main sum of money came from the steel industry.
