The Ziffs – $14.4B
A couple of years ago, the highly influential Ziff family shut down their hedge funds and closed both their American and UK branches. However, it hardly matters since the Ziff Brothers Investments firm will forever be remembered for the huge impact they made on Wall Street. This remains true despite the fact that Dirk and Robert Ziff have since gone their own ways to go after different businesses. The family’s wealth dates back to nearly a century ago, when their grandfather William Sr. had a publishing company. The Ziff Davis firm kept growing after William Jr. took over the leadership. The company are best known for these publications: PC Magazine and Car and Driver. Their currently wealth comes from their investments. Dirk is now the owner of a capital company based in New York.
