The Story

In a converted auto repair shop in West Chester, chemist G. Raymond Rettew solved one of World War II's most urgent problems: how to make penicillin in quantity. Working with Wyeth Laboratories in 1943, his lab produced and shipped more of the new antibiotic to the armed forces than any other in the world. The drug that had been a laboratory curiosity became a battlefield lifesaver.

Why it matters

Mass-produced penicillin saved countless soldiers from fatal infection and launched the antibiotic age that reshaped modern medicine.

Humphry Marshall (1722-1801)

West Bradford Township, PA · est. 2014

Humphry Marshall, a Chester County Quaker, became one of the first commercial nurserymen in the new nation and, in 1785, wrote Arbustum Americanum: The American Grove, the first book on North American trees and shrubs by an American. From the house he built here, he shipped native plants to eager European collectors curious about the flora of the New World. His work earned him the title Father of American Dendrology, and his specimens graced the royal gardens of King George III and King Louis XVI.

Glen Mills

Thornbury Township, PA · est. 1997

This Delaware County hamlet grew up around water-powered industry that reached back before the Revolution, when a forge was raised here around 1739 and Pennsylvania's first iron-slitting mill followed in 1746. Nearly a century later the Willcox family turned the site to papermaking, and in the years after the Civil War their mill produced paper for United States currency—engineered so cleverly to defeat counterfeiters that it earned international fame. By the time the railroad station arrived in 1882, Glen Mills bustled as a center of commerce.

Joshua Pusey

Middletown Township, PA · est. 1993

A Civil War veteran and Philadelphia attorney, Joshua Pusey turned an inventor's mind to an everyday problem and in 1892 patented the paper matchbook. He sold the patent to the Diamond Match Company three years later, and soon millions of the little folders were rolling out each year to light stoves, lamps, and cigarettes across the country. One of nearly forty patents in his lifetime, it was the work of a man from an old Quaker family who lived here at his home "Maple Linden."

Valley Forge General Hospital

Schuylkill Township, PA · est. 2012

Opened in 1943 as America mobilized for total war, Valley Forge General Hospital grew into one of the nation's largest military hospitals, sprawling across more than 100 buildings and treating over 3,000 patients at a time. Its surgeons became pioneers in the era's most harrowing wounds — reconstructing shattered eyes, rebuilding burned faces, and advancing the young field of rehabilitation. Its wards received the broken bodies of three wars — World War II, Korea, and Vietnam — before the hospital closed in 1974.
