Pritzker was born to a Jewish family in Chicago, Illinois, the daughter of Audrey (née Gilbert) and Robert Pritzker. She has two siblings: Jennifer N. Pritzker (b. James, 1950), a retired Lt Colonel in the U.S. Army and founder of the Pritzker Military Library, and Linda Pritzker (b. 1953). Her parents divorced in 1979. In 1981, her mother remarried Albert B. Ratner, the co-chairman of Cleveland-based real estate developer Forest City Enterprises. In 1980, her Father remarried to Irene Dryburgh with whom he had two children: Matthew Pritzker and Liesel Pritzker Simmons.
Her Father Diversified the Chicago-based family Business, the Marmon Group - along with his brothers Jay Pritzker and Donald Pritzker - building it into a portfolio of over 60 Diversified industrial corporations. They also created the Hyatt Hotel chain in 1957 and owned Braniff Airlines from 1983–1988. The family has been divesting its assets: in 2006, the family sold Conwood, a smokeless tobacco company, for $3.5 billion to cigarette company Reynolds American Inc; in 2007, the family sold control of the Marmon Group to Warren Buffett's Berkshire Hathaway for $4.5 billion; and in 2010, the family sold its majority stake in Transunion, the Chicago-based credit reporting company, for an undisclosed amount to Chicago-based private-equity firm Madison Dearborn Partners.
