Imagine a boy who loved stories but could not afford a single book of his own. Andrew Carnegie was that boy — and he grew up to become one of the richest men in the world, then spent his fortune building about 2,500 free public libraries so no child would ever be shut out of a book the way he once was.
Andrew was born in 1835 in Dunfermline, Scotland, into a poor family. His father wove cloth by hand, but new machines were taking that work away. In 1848, when Andrew was twelve, the family sailed across the ocean to Allegheny, Pennsylvania, hoping for a better life.
That better life started small. Andrew's first job was as a bobbin boy in a cotton mill, changing spools of thread through long, noisy days for just $1.20 a week. Next he became a telegraph messenger boy, racing messages across the city and teaching himself to understand the clicking code by ear.
Books were still out of reach — until a kind man named Colonel James Anderson opened his personal library of 400 books to working boys every Saturday night. Andrew borrowed one after another, and he quietly promised himself that someday he would help other poor children find books too.
As he grew up, Andrew worked for the railroad, made clever investments, and then turned to steel. His company used the Bessemer process to make steel faster and cheaper than ever, and that strong metal built America's railroads, bridges, and towering buildings. Andrew became astonishingly wealthy.
In 1901 he sold his steel company for more than $300 million. But he did not want to die rich. He believed in an idea he called The Gospel of Wealth: people with great fortunes should give them away to help others. Carnegie gave away almost 90 percent of everything he had.
And he kept his childhood promise. Along with Carnegie Hall in New York and many schools, he funded roughly 2,500 libraries where anyone could walk in and read for free. Andrew died in 1919, but every one of those library doors still opens on a promise a poor boy once made to himself.
