JB Pritzker (Gov. of Illinois) and Penny Pritzker's mother died when she fell out of the side of a tow truck? Now that's a weird story.

Penny Pritzker was born in Chicago in 1959, the daughter of Sue (née Sandel)[3] and Donald Pritzker. She is a member of the Pritzker family of Chicago, a wealthy and influential business family.[4] Donald Pritzker was one of the co-founders of Hyatt Hotels. He moved the family to Atherton, California, where business for the Hyatt Hotels began to grow.[5] Penny has two younger brothers, Tony (b. 1961) and J. B. Pritzker (b. 1965).[1]

Young Penny would accompany her father to the hotels and check the cleanliness of the ladies restrooms. In 1972, Don died suddenly of a heart attack when Penny was 13 years old. Following Don's death, Sue began battling depression, requiring Penny to at times care for her mother and her younger brothers.[1] At age 16, Penny wrote a letter to her grandfather, and head of the family business empire, A. N. Pritzker, in which she asked why he talked business with the men in the family and not with her.[6] Finally realizing Penny's interest in business, A. N. provided her with a summer course in accounting.[6]

Penny attended Castilleja School until 1977.[7][8] She graduated with a Bachelor of Arts in economics from Harvard College in 1981.[9] The following year, Penny's mother died after falling out of the passenger side of a tow truck. Penny returned to school, earning both a Juris Doctor and a Masters of Business Administration from Stanford University in 1985.[1]
