Who was Columbus and what did he do?

Christophorus Columbus, who called himself Cristóbal Colón, was born in 'The Most Serene Republic of Genoa', 300 years before became a part of Italy. He sailed in the name of Spain trying to find a new route to Asia across the Atlantic. He instead found a whole new world, the Americas a fact which he never acknowledged. He is known as the first man to found a colony in the Americas.
Columbus was born on October 30, 1451 and died on May 6, 1506. He was married from 1479--85 when his wife died leaving him with his two kids: Cynthia and Alex. Columbus was broke, when he died, because of the Granada campaign. I don't know what that was.
