1933: Century of Progress — the city’s second world’s fair — opened in Chicago.

1968: Chicago Bears owner George Halas, 73, announced his retirement as the team’s head coach. Halas finished with a regular-season record of 318-148-31 in 40 seasons.
Halas named Jim Dooley, a longtime assistant and former player, to replace him. Halas’ 1968 send-off of “Good luck, kid” to his successor immediately turned to bad luck and haunted Dooley through season records of 7-7, 1-13, 6-8 and 6-8.
Enthusiastic and innovative, a true “football man,” Dooley presided over four of the darkest and worst years in Bears history.

1993: The $618 million International Terminal was unveiled at O’Hare International Airport. The 1.2 million-square-foot, glass-and-steel building with dramatic, curving roof and skylights was completed following more than two years of construction. This facility, officially named Terminal 5, included 21 gates, 156 ticket counters and was estimated to handle 4 million passengers annually. It was the last project of a $2 billion O’Hare revitalization and expansion program begun a decade earlier.
The terminal was expanded in 2023.

2012: Paul Konerko hit a tie-breaking three-run home run — his 400th with the Chicago White Sox — in a 12-6 win over the Cleveland Indians. The offensive outburst gave the Sox nine or more runs in four consecutive games. The White Sox last accomplished that feat June 27-30, 1938.
