Who was the richest man in all of history?Source: The Washington Post
It's fairly easy to figure out who the wealthiest person in the United States is. Just look at the Forbes 100, and you see it's Bill Gates, worth $67 billion. Carlos Slim, the Mexican titan, is worth $73 billion, a measly nine percent more. And with a bit of Googling, you could find similar answers for people across history. The famous Roman politician Marcus Crassus was thought to be among the republic's wealthiest, with a net worth of 200 million sesterces. Fast forward through time, and John D. Rockefeller is said to have had a peak of $1.4 billion in 1937.
