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.

In 1986, Agnes D. Lattimer made history as the first Black woman medical director of a major American hospital, leading Cook County Hospital.

Dr. Lattimer had this to say about her career: “I was able to impact all of the medical and surgical services by introducing a ‘Philosophy of Caring’ for the patients which emphasized focusing on competence and compassion in the delivery of medical care.”

🗳️ We love mayoral elections so much, Chicago, that we’re getting two this year. 🗳️

But how much do you really know about how we’ve chosen our city’s leader for almost the past two centuries?

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.
