The Story

The Schuylkill Arsenal, built in the early 1800s, was where Meriwether Lewis gathered and stored the supplies he purchased in Philadelphia before shipping them west to Pittsburgh for the start of his great expedition. For more than a century afterward the arsenal outfitted American soldiers, supplying military goods through the Civil War and both World Wars. It stood until 1963, when it was finally razed.

Why it matters

From the launch of the Lewis and Clark Expedition to the wars of the 20th century, this depot quietly provisioned the American enterprise of exploration and arms for over 150 years.

Meriwether Lewis (1774-1809)

Philadelphia, PA · est. 2003

With William Clark, Meriwether Lewis led the transcontinental expedition of 1803–1806 that opened the newly purchased Louisiana Territory to American knowledge. Philadelphia, then the young nation's scientific capital, was where Lewis prepared for the journey and where he later deposited many of its precious specimens, journals, and artifacts. The city's naturalists and institutions helped translate the expedition's discoveries into lasting science.

Robert Patterson (1743-1824)

Philadelphia, PA · est. 2004

Robert Patterson chaired mathematics and served as vice-provost at the University of Pennsylvania in the early 1800s, a respected man of science in the young republic. In 1803 he tutored Meriwether Lewis in the celestial navigation and surveying skills the explorer would need to chart the unknown West. From this home Patterson helped equip the Lewis and Clark Expedition with the mathematical tools of discovery.

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.

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.
