Eddystone Rifle Plant

Eddystone, Delaware County, Pennsylvania

Marker Inscription

Built to make P14 Enfield rifles for the UK in 1914, the factory was the nation's largest during WWI. It produced a modified version of the firearm after the US entered the war, designated the Model 1917. It was the most common rifle issued to US soldiers and more than half were made here. Employing 15,000 workers, 20% of which were women, the plant fabricated over a million rifles, accounting for 47% of total US wartime production.

The Story

When the guns of the First World War fell on Europe in 1914, an arms plant rose on the Delaware River at Eddystone to turn out Enfield rifles for Britain. After the United States entered the war, the factory retooled to make the American Model 1917 — and became the single largest rifle producer in the nation, employing some 15,000 workers, a fifth of them women. Its lines fabricated more than a million rifles, nearly half of the country's entire wartime output.

Why it matters

Eddystone shows how the Philadelphia region's factories and workforce, women included, powered America's rapid transformation into an industrial arsenal during World War I.

Sun Shipbuilding and Dry Dock Company

Chester, PA · est. 2007

Founded by the Pew family in 1916 along the Delaware River, Sun Shipbuilding and Dry Dock Company grew during World War II into the largest single shipyard on earth, employing more than 35,000 workers. Sun pioneered the all-welded ship and the T-2 oil tanker that became the standard across American yards, building over 250 wartime tankers—roughly 40 percent of the world's total—and repairing more than 1,500 damaged vessels. The yard operated on this Chester waterfront until 1982.

Leiper Railway

Nether Providence Township, PA · est. 1955

Built in 1809-10 by Thomas Leiper and surveyed by John Thomson, the Leiper Railway ran about three-quarters of a mile to haul stone from quarries on Crum Creek down to a landing on Ridley Creek. It is remembered as the first railway in Pennsylvania and the first in America to be laid out by survey. Horses drew the loaded cars along its wooden rails decades before the steam locomotive age.

Caleb Pusey

Upland, PA · est. 1967

Caleb Pusey (1651–1727), an English-born Quaker lastmaker, purchased 250 acres from William Penn in 1681, the very year Penn received his charter for Pennsylvania. Serving as Penn's business agent, grist mill manager, and a colonial officeholder, Pusey was a trusted figure in the young colony—and his home is remembered as a place Penn himself visited. His house survives as a rare tangible link to Pennsylvania's founding generation.

Minquas' Path

Rose Valley, PA · est. 1947

Long before roads crossed this part of Pennsylvania, an Indian trading path ran west from the Delaware to the country of the Susquehannock — called Minquas by the Dutch and Swedes — and forded Ridley Creek near this spot. Along it moved one of the most valuable commodities of the seventeenth-century Atlantic world: beaver pelts, carried east by the thousands each year to the small Dutch and Swedish trading posts on the Delaware. This single artery tied the fur-rich interior to a global market hungry for felt hats, and helped decide which European power would prosper on the river.
