On this day, May 22, 1855, a tornado developed in the town of Jefferson — present-day Jefferson Park on Chicago’s Northwest Side. The Richter scale had not yet been invented so the tornado’s intensity was never officially recorded. Source: Chicago Tribune, 1855.

It’s #WomensHistoryMonth2023 in @cookcountygov spotlighting women who provided leadership to Cook County throughout our history. Banners here were from 2021 and, in just two years, many more women have joined County leadership. All the new faces soon, but first, a look back.
