According to Forbes, Amazon frontman Jeff Bezos has been named the richest man ever…sort of. In 1999, his fortune topped $100 billion. As of 2018, his fortune has reached $105 billion. So in simple dollar terms he is richer. Adjusting for inflation, Bezos still has ways to go before he can be considered the richest man in history. Comparatively speaking, John D. Rockefeller is often called the richest American ever, since he was the first billionaire. His fortune was estimated at $1.5 billion in 1918, which in inflation-adjusted terms would be about $24 billion today. In pure dollars, Bezos is the richest, but he would still need to amass a few trillion more before he can hold the crown as the richest in history.
