Today, July 13th, 2020, marks the 25th anniversary (to the day) of the beginning of the worst heat wave in Chicago history, a human disaster that resulted in over 700 deaths in and around Chicago that were directly linked to the effects of the record-breaking heat that was experienced for an entire week. Erik Klinenberg's definitive book about the disaster is titled "Heat Wave: A Social Autopsy of Disaster in Chicago." This interview was recorded and initially broadcast back in 2002.
