Who's the single most successful person ever?

The person in history who has made the most money, not necessarily inherited it like British nobility or princes from Saudi Arabia. Simply put: who has made the most money ever. Is it that Rockefeller guy? Maybe the owner from Goldman Sachs? The McDonald's owner? Tell me what you think, it could be from any time period even if you know someone from the stone age that was extremely successful for his (or her) time lol...
