According to a statement from his family, Duchossois "passed away peacefully" at his home in Barrington Hills on Friday.
He rebuilt the racecourse after a fire destroyed it in 1985, making it into a world class facility with the famed "Arlington Million."
The Chicago native and philanthropist was also a decorated war hero. His son told ABC7 his combat experience helped shape his success.
"Having been so close to death during World War II, he didn't think that any mountain was too high, he'd sorta been there," Craig Duchossois said. "And so, he developed a sense of grit and can-do attitude that is exemplary."
