Benjamin Smith Barton (1766-1815)

Philadelphia, PA · est. 2004

Benjamin Smith Barton was among early America's foremost men of science, a physician and University of Pennsylvania professor who wrote the first botany textbook published in the United States. In 1803, at the request of the expedition's planners, he tutored Meriwether Lewis in natural history to prepare him to observe and record the plants, animals, and peoples of the West. From this Philadelphia home he stood at the crossroads of American medicine, natural science, and continental exploration.

Caspar Wistar (1761-1818)

Philadelphia, PA · est. 2000

Caspar Wistar, one of early America's most respected physicians, lived here while serving as professor of anatomy at the University of Pennsylvania and president of both the American Philosophical Society and the Pennsylvania Abolition Society. In 1803, at Thomas Jefferson's behest, he tutored Meriwether Lewis in medicine and paleontology to prepare him for the Corps of Discovery's journey west. Wistar moved easily among the scientific, medical, and reform circles of the young republic.

Walnut Street Theatre

Philadelphia, PA · est. 1996

When the Walnut Street Theatre opened its doors in 1809, the United States was barely a generation old and professional theater was still a novelty on the young republic's stages. It has raised its curtain continuously ever since, making it the oldest playhouse still in use in the English-speaking world and a stop for celebrated performers from both sides of the Atlantic. Now a National Historic Landmark, it survived changing tastes, fires, and centuries of competition to keep the footlights burning.

Wills Eye Hospital

Philadelphia, PA · est. 2009

Opened in 1834, Wills Eye Hospital was the first medical institution in the United States devoted entirely to diseases of the eye, and the first to train physicians in the young specialty of ophthalmology. Growing from that pioneering mission, it earned a worldwide reputation for its advances in surgical and medical eye care. Its focus on patient care, research, and teaching set a standard for specialized American medicine.
