Jay Pritzker died in 1999, breaking up the family's wealth.

At the time of Jay Pritzker's death, Forbes estimated his net worth to be $13.5 billion as a result of his countless business ventures.

By then, there were 182 Hyatt hotels, with another 34 under construction. The year before, the Hyatt Corporation saw $3 billion in revenue. Before his death, Jay had named his son, Tom Pritzker, his successor in 1995. He also established leadership roles for Nick Pritzker and Penny Pritzker.

After the death, the family had a falling out regarding how to handle the fortune, which resulted in a breaking up of familial assets that took nearly a decade to untangle and included legal battles.

Today, Tom Pritzker is still the chairman of Hyatt. Other Pritzkers went on to become film producers and state governors. Eleven total family members are currently billionaires — and nine were featured on 2019's Forbes 400 list. Together, they are one of America's wealthiest families.
