In the late 1800s, although six medical schools were already in existence, five physicians—Charles Warrington Earle, Abraham Reeves Jackson, Daniel Atkinson King Steele, Samuel McWilliams and Leonard St. John—decided to open their own proprietary medical school. They pooled together $5,541.78, purchased a piece of land and secured a certificate of incorporation. The new school, located on Harrison and Honore streets, was named the College of Physicians and Surgeons of Chicago (commonly referred to as P&S). Its doors opened on September 26, 1882, with a class of 100 students and a faculty of 27 physicians.
