Net worth: $33.5 billion
Source of wealth: Hyatt Hotels
A.N. Pritzker and sons Jay, Donald, and Robert created the family's wealth by founding the Hyatt Hotel chain and investing in holdings, such as Marmon Group. Today, the fortune is split among 13 family members, 11 of whom are billionaires. They reportedly spent much of the 2000's arguing over trusts, ultimately dividing up the fortune at the end.
Members of the Pritzker family have also been involved in politics. Penny Pritzker, Donald's daughter, is the former US Secretary of Commerce. Her brother, J.B. Pritzker was the national co-chairman of Hillary Clinton's 2008 presidential campaign and the Democratic candidate in the 2018 Illinois gubernatorial election.
