Andrew Carnegie, $310 billion
Andrew Carnegie was an unbelievably rich and powerful businessman. He became famous in the middle of the 19th century. Carnegie was born in Scotland and he was from a very poor family that moved to the US at the end of the 1840s. After some successful investments into a series of companies, Carnegie set up his own company, U.S. Steel, that made him the biggest part of his fortune of $310 billion. He is also known as a man who spent most of this money on different donations, so he is remembered as one of the most prominent philanthropists in the world.
