Daniel Ziff is the youngest son of late William B Ziff Sr., who was the owner of the Ziff-Davis Inc., an American publishing company which was later sold out. Daniel and his two brothers reinvested that money in their hedge fund, ‘Ziff Brothers Investments’. Ziff went to Trinity in New York City then got a BA from nearby Columbia. The name may sound familiar, as the elder Ziff also invested in Daniel Och, number #10 on our list.
