The Pritzker family is an American family engaged in various business enterprises and philanthropy, and one of the wealthiest families in the United States (staying in the top 10 of Forbes magazine's "America's Richest Families" list since the magazine began such listings in 1982). Its major fortunes started in the 20th century, particularly through the expansion of the Hyatt Hotels Corporation by Jay Pritzker.
Family members still largely own Hyatt and owned the Marmon Group, a conglomerate of manufacturing and industrial service companies prior to its sale to Berkshire Hathaway. They have also had holdings in the Superior Bank of Chicago (which collapsed in 2001), the TransUnion credit bureau, Braniff airlines, McCall's magazine, and the Royal Caribbean International cruise line.
