He helped establish Pennsylvania Hospital and the Academy and College of Philadelphia, which became the University of Pa. He founded the City of Allentown and was Chief Justice of the Pa.

The Story
William Allen was one of colonial America's richest men, and his fortune helped build the institutions of early Philadelphia. He backed construction of the State House, now Independence Hall, and helped found Pennsylvania Hospital and the college that became the University of Pennsylvania. He established Allentown and served as Chief Justice of Pennsylvania's Supreme Court, but as revolution neared he broke with the patriot cause and remained a Loyalist until his death at his Mount Airy estate.
Why it matters
Allen embodies the colonial elite whose wealth built enduring civic institutions, even as the Revolution split such men between patriot and Loyalist loyalties.
The story behind this marker
AI contextThe era
William Allen's long life spanned the arc from colonial Philadelphia to the eve of American independence. Born in 1704, he came of age when Pennsylvania was a thriving British colony and when a small circle of merchants and gentlemen wielded enormous influence over its commerce, courts, and civic life.
This was an era of institution-building. Philadelphia was becoming one of the most important cities in British North America, and its leading citizens were founding the hospitals, colleges, and public buildings that would outlast them. Great private fortunes underwrote much of that public good.
But it was also an era heading toward rupture. As Allen grew older, the ties between colony and crown began to fray, forcing men of wealth and standing to choose sides in a conflict that would divide families, fortunes, and consciences.
People & events
Allen was one of colonial America's wealthiest men, and he put that wealth to work in ways still visible today. He supported the construction of the State House — the building the world now knows as Independence Hall — and helped establish Pennsylvania Hospital and the Academy and College of Philadelphia, which grew into the University of Pennsylvania.
His reach extended beyond the city. He founded the community of Allentown, and he served as Chief Justice of the Pennsylvania Supreme Court, one of the highest offices in the colony.
Yet Allen's story turns on a hard choice. Though he began by supporting colonial interests, as revolution neared he broke with the patriot cause and became a Loyalist. He remained one until his death in 1780, at his estate called Mt. Airy — the name that the surrounding community carries to this day.
Its place in the American story
Allen's life captures a truth about the Revolution that is easy to forget: not every prominent, public-spirited colonist became a patriot. Men of his generation and station faced a genuine dilemma, and reasonable, established citizens landed on opposite sides.
His legacy is therefore layered. The institutions his fortune helped build — a great hospital, a great university, the very hall where independence would be declared — became pillars of the new nation, even though their benefactor could not bring himself to endorse the break with Britain.
That tension is his significance. He embodies the colonial elite whose money and energy built enduring American institutions, and who then found themselves divided, sometimes tragically, when those institutions helped give birth to a country he did not support.
If you visit
Begin with the name of the place itself. The community of Mt. Airy takes its name from Allen's estate, so the geography around you is part of the story — a rare case where a man's country home left its mark directly on the map.
As you explore, hold two ideas at once. This was the home of a founder of lasting institutions and a Loyalist who turned away from the Revolution. That complexity is worth sitting with; history is rarely as tidy as we'd like, and Allen is a fine reminder of it.
The marker also makes a natural launch point for a wider tour. The threads that run from here — to Independence Hall, to Pennsylvania Hospital, to the University of Pennsylvania — connect this quiet neighborhood to some of the most important places in the American story.

Abington Presbyterian Church Cemetery
Abington Township, PA · est. 1992
Founded in 1714, Abington Presbyterian Church stood at the heart of one of Montgomery County's oldest colonial communities, with its adjoining burial ground opening in 1719 and receiving its first recorded interment in 1728. The grounds saw Revolutionary War skirmishing as armies maneuvered across the Philadelphia countryside, and generations of pastors, educators, and war veterans were laid to rest here. The cemetery links Abington to the wider intellectual worlds of Philadelphia and Princeton through the notable clergy and teachers buried within it.
Wissahickon Inn
Philadelphia, PA · est. 1988
When it opened on May 30, 1884, the Wissahickon Inn was a grand 250-room summer resort, built by industrialist Henry H. Houston and designed by the noted architects G.W. and W.D. Hewitt. As Chestnut Hill developed into a fashionable suburb, the sprawling hotel found a second life in education. Since 1898 it has served Chestnut Hill Academy, the school that acquired the building outright in 1940.
Battle of Germantown
Philadelphia, PA · est. 1996
On October 4, 1777, the Revolutionary War came to the doorstep of Cliveden, the elegant country home of Pennsylvania Chief Justice Benjamin Chew. A British regiment barricaded itself inside the stone mansion and beat back a determined American assault, and more than seventy men fell on these grounds. Though Washington's army was defeated, the audacity of his coordinated attack impressed European observers.
Wyck House and Rose Garden
Philadelphia, PA · est. 2025
Wyck sheltered nine generations of a single Quaker family whose interests ranged across science, education, glassmaking, horticulture, and brewing. The oldest part of the house dates to 1690, and in 1824 the noted architect William Strickland reshaped the 1720s dwelling into the home that stands today. In 1821 Jane Bowne Haines laid out a rose garden that grew to hold more than fifty rare cultivars, among the oldest surviving gardens of its kind in its original plan.
