On April 10, 1917, four days after the United States declared war on Germany, an explosion at the Eddystone Ammunition Corporation's artillery shell plant in Eddystone, Pennsylvania, killed 139 people. The majority were women and girls who worked in the loading room, loading shells with black powder. 55 of the victims could not be identified and were buried in a mass grave. Hundreds more were injured. The victims were arguably among the first American casualties of World War I. The explosion was initially blamed on German saboteurs, and later on Russians. It may in fact have been an accident caused by malfunctioning equipment.

Baldwin Locomotive Works (BLW) was an American manufacturer of railway locomotives from 1825 to 1951. Originally located in Philadelphia, Pennsylvania, it moved to nearby Eddystone in the early 20th century. The company was for decades the world's largest producer of steam locomotives, but struggled to compete when demand switched to diesel locomotives. Baldwin produced the last of its 70,000-plus locomotives in 1951, before merging with the Lima-Hamilton Corporation on September 11, 1951, to form the Baldwin-Lima-Hamilton Corporation.

Crum Creek (from the Dutch, meaning "crooked creek") is a creek in Delaware County and Chester County, Pennsylvania, flowing approximately 24 miles (39 km), generally in a southward direction and draining into the Delaware River in Eddystone, Pennsylvania. It begins in a swamp (formerly a lake, dammed out) near Newtown Square, Pennsylvania along which several mills were established in the 19th century. Right afterward it crosses under Pennsylvania Route 29 and winds one and a half miles (2.4 km) downstream until it hits the hamlet of Crum Creek. It later flows into the Delaware River near Philadelphia. Two notable landmarks along the creek's course are high trestles: a trolley trestle about 30 feet (9.1 m) high runs across the creek in Smedley Park, in Nether Providence Township; this trestle carries the Southeastern Pennsylvania Transportation Authority's 101 trolley line from Media, Pennsylvania across the creek. About a mile (1.6 km) south, a 1,000-foot-long (300 m), 100-foot-high (30 m) trestle carries SEPTA's Media/Wawa Line commuter railroad line across the creek, which by now runs through a deep valley. The trestle is located in the Crum Woods, 200 acres of forest surrounding the creek that constitutes part of the campus of Swarthmore College. This tract, one of the largest patches of woodland remaining in Delaware County, is managed by the college's Scott Arboretum. The trestle is half in Nether Providence Township (west of the creek) and half in Swarthmore borough (east of the creek). Baltimore Pike also crosses the Crum by Smedley Park in Nether Providence Township. A stone bridge carrying the highway was erected in 1924 with a 70-foot-tall (21 m) arch commemorating the 282 men and 2 women from Delaware County who died in World War I. This arch was demolished in 1958 when the highway was widened. The memorial tablets were moved to the nearby entrance of Smedley Park.Crum Creek was dammed in 1931 near Pennsylvania Route 252 to fill Springton Lake (also known as Geist Reservoir), an approximately 391-acre (1.58 km2) drinking water reservoir maintained by Aqua America.
