The house at 912 Walnut Street sheltered two remarkable George McClellans. The father, a physician, founded Jefferson Medical College and lived here until his death in 1847. The son, raised here as a boy, grew up to command the Army of the Potomac in the Civil War's early years and to run for president against Abraham Lincoln in 1864.

Established in 1855, the Children's Hospital of Philadelphia was the first hospital in the nation devoted entirely to the care of children. Over the decades it became a proving ground for pediatric medicine, developing lifesaving vaccines, pioneering newborn surgical techniques, and advancing treatment for childhood cancer. Its founding reflected a growing 19th-century conviction that children's health deserved dedicated, specialized care.

The paleontologist and zoologist Edward Drinker Cope lived and worked in this Philadelphia neighborhood in his later years, producing a torrent of scientific papers that described hundreds of fossil and living species. He is best remembered for the "Bone Wars," his fierce, decades-long rivalry with Othniel Charles Marsh of Yale to unearth and name new dinosaurs. Their competition, however bitter, dramatically expanded American knowledge of prehistoric life.

Every spring since 1895, the University of Pennsylvania's Franklin Field has hosted the Penn Relays, the oldest and largest track and field relay carnival in the country. What began in the Gilded Age as a novel collegiate competition grew into a rite of passage for generations of schoolboys, college stars, and Olympians, whose races here set American and world records. The meet's unbroken run through wars and depressions made it a fixed point on the American sporting calendar.
