Industrialist and philanthropist, Andrew Carnegie (1835-1919) is better known, today, as the steel tycoon who started over 2,800 libraries. His rags-to-riches tale is also among the most famous in American history.

After moving to Pennsylvania from Scotland, a teenage Carnegie worked hard in factories, invested his money wisely and, within a span of four decades, managed to gain control of a number of manufacturing plants that grew to become the Carnegie Steel Company.

He is equally -- if not more -- famous for his donations of over $350 million to further public education: an ironic gesture coming from a dropout.

The author Dale Carnegie was a distant relative, gaining fame for his 1937 bestseller, How to Win Friends and Influence People. And here's another titbit to chew on: During the American Civil War, Andrew Carnegie avoided the battlefield by paying a replacement the sum of $850.
