There are various methods of comparing individuals' wealth across time, including using simple inflation-adjusted totals or calculating an individual's wealth as a share of contemporary gross domestic product (GDP). For example, economic blogger Scott Sumner noted in 2018 that Rockefeller was worth $1.4 billion when he died in 1937, which was about $24 billion in dollars adjusted to 2018. Meanwhile, Bill Gates in 1999 was worth nearly $150 billion in dollars adjusted to 2018. The second-richest person in terms of wealth vs. contemporary GDP is disputed. Most sources list Andrew Carnegie, but others say Gates, Cornelius Vanderbilt I, John Jacob Astor IV, or Henry Ford. Lower ranks are a matter of even bigger debate. Vanderbilt left a fortune worth $100 million upon his death in 1870 ($2,100,000,000 today). As the United States became the foremost economic power in the world by the late 19th century, the wealthiest men in America were often also the wealthiest men in the world."@en . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
