With 115 skyscrapers, ranging from the 1924-built Chicago Temple Building to the recently topped out Loews North Park Drive building, Chicago is a world leader in the number and style of its skyscrapers.

The history of skyscrapers in Chicago goes back to 1885 with the construction of the iconic Home Insurance Building, widely recognized as the world’s first skyscraper.

Northwestern Memorial Hospital and Loyola University Medical Center are nationally ranked for cardiology and heart surgery. They can thank Daniel Hale Williams, an African-American medical pioneer who performed the first successful open-heart surgery on a patient right here in Illinois.

Daniel Hale Williams, originally born in Hollidaysburg, Pennsylvania in 1856, moved to Chicago as a young aspiring surgeon. He began as an apprentice for an accomplished surgeon and studied at Chicago Medical College.
