Looking for inspiration in your quest to become a billionaire? This map from cost information website HowMuch.net, spotted by Digg, highlights the richest person in history who hails from each of the 50 states.

More billionaires live in the U.S. than in any other country, but not every state has produced a member of the Three Comma Club (seven states can only lay claim to millionaires). The map spans U.S. history, with numbers adjusted for inflation. One key finding: The group is overwhelmingly male, with only three women represented.

The richest American by far was John D. Rockefeller, repping New York with $257.25 billion to his name. Amazon's Jeff Bezos and Microsoft's Bill Gates clock in at the third and fifth richest, respectively. While today they both make their homes in the exclusive waterfront city of Medina, Washington, this map is all about birthplace. Since Gates, who is worth $90.54 billion, was born in Seattle, he wins top billing in the Evergreen State, while Albuquerque-born Bezos's $116.57 billion fortune puts New Mexico on the map.

The richest woman is South Carolina's Anita Zucker ($3.83 billion), the CEO of InterTech Group, a private, family-owned chemicals manufacturer based in Charleston. Clocking in at number 50 is the late, great socialite Brooke Astor—who, though a legend of the New York City social scene, was a native of New Hampshire—with $150 million.
