Who was the richest person of all time?

But wealth does not always equate to waste and eccentricity. Many of the wealthiest people in history were known for their thrift. Warren Buffett, one of the most successful investors of all time, is famous for living a modest life and living in the same house he bought in 1958. This down-to-earth nature, combined with his unerring instinct for investing, makes him a fascinating case study for anyone who wants to not only acquire wealth, but also preserve it.
