The Story
Allentown State Hospital opened as Pennsylvania's first state institution to treat mental illness through homeopathic medicine, part of a national movement to give the mentally ill dedicated care. Among those who worked here was Dr. Solomon C. Fuller, the first African American psychiatrist, who served as a consulting pathologist, and in 1930 a pioneering Children's Institute opened under Dr. Henry Klopp. In 1999 the hospital drew international attention as the first state facility to abandon patient seclusion in favor of its Psychiatric Emergency Response Teams.
Why it matters
The hospital's history traces the long American struggle to treat mental illness humanely, from 19th-century reform ideals to the modern movement away from restraint and seclusion.
The story behind this marker
AI contextThe era
To understand Allentown State Hospital, you have to picture the world of mental-health care in the decades before it opened. For much of the nineteenth century, Americans with serious mental illness were too often warehoused in almshouses and jails, or hidden away at home. A reform movement — driven by advocates who insisted the mentally ill deserved treatment rather than confinement — pushed states to build dedicated public hospitals where care, not punishment, was the goal.
Pennsylvania was an early and energetic participant in that movement. By the time this institution took shape in the Lehigh Valley, the state was building a network of public hospitals meant to bring order, medicine, and a measure of dignity to a population that earlier generations had simply set aside.
What set this place apart was its founding philosophy. It opened as Pennsylvania's first state hospital to treat mental illness through homeopathy — a distinct medical school of thought that was widely practiced and hotly debated in that era. Choosing that approach for an entire state facility was a deliberate statement about how these patients should be treated, and it planted the hospital squarely in the medical arguments of its age.
People & events
The names attached to this hospital tell a story of firsts. Dr. Solomon C. Fuller, recognized as the first African American psychiatrist, served here as a consulting pathologist. In an era when the doors of American medicine were largely closed to Black professionals, his work at a state institution like this one is remarkable — a reminder that pioneers often did their most important labor in laboratories and wards far from the spotlight.
In 1930 the hospital opened a Children's Institute under the direction of Dr. Henry Klopp — described as one of the first of its kind. That is worth pausing over. The idea that children with mental or developmental needs required their own specialized, dedicated care, rather than being folded in among adults, was still taking hold. A facility built around that principle was ahead of much of the country.
Decades later, the institution made news again. In 1999 it became the first state hospital to end the use of patient seclusion, and its Psychiatric Emergency Response Teams drew international attention. Where an older model relied on locking a distressed patient away, this new approach sent trained people toward the crisis to de-escalate it. It was a philosophical reversal as much as a procedural one.
Its place in the American story
Trace the arc of this single hospital and you have, in miniature, the long American struggle to treat mental illness humanely. It begins in the reform ideals of the nineteenth century, when the very existence of a public hospital devoted to care was itself progress. It runs through the twentieth-century push to specialize — to recognize that children, in particular, needed something different from what adults received.
And it culminates in one of the defining shifts of modern psychiatry: the movement away from restraint and seclusion toward de-escalation and rapid, humane response. When this hospital ended seclusion and built its emergency-response model, it was helping to answer a question that institutions across the country and beyond were wrestling with — how do you keep both patients and staff safe without resorting to the confinement that earlier eras took for granted?
The presence here of a figure like Dr. Solomon C. Fuller adds another national thread: the slow, hard-won integration of American medicine, and the outsized contributions of Black physicians who advanced their fields despite the barriers of their time.
If you visit
This marker stands in Allentown, in Pennsylvania's Lehigh Valley, and reading it is a chance to look past the surface of a large state institution and see the human history layered inside it. As you stand there, remember that a place like this was not simply a building — it was a set of choices about how society treats its most vulnerable members, choices that changed dramatically over the hospital's lifetime.
Let the marker be an invitation to think about the people named on it. A pathologist breaking barriers in his profession. A doctor opening one of the country's early institutes for children. Staff, generations later, retraining themselves to walk toward a crisis rather than lock a door on it.
If you're building a road trip through the Lehigh Valley, this is a stop that rewards reflection more than spectacle. Pair it with the region's other historic sites, and let it prompt the kind of conversation — about how care and compassion evolve — that a good marker is meant to start.

Harriet A. Baker
Allentown, PA · est. 1990
Around 1900, the African-American evangelist Harriet A. Baker opened a mission on North Penn Street in Allentown and preached there until her death. Her small storefront ministry took root, and in 1914 it became the first home of St. James A.M.E. Zion Church, which built its permanent home on this spot in 1936. Baker was part of a wider tradition of Black women preachers who founded and sustained congregations at a time when the pulpit was rarely open to them.
Liberty Bell Hiding Place
Allentown, PA · est. 2022
In the anxious autumn of 1777, with the British army marching on Philadelphia, the Continental Congress ordered the city's bells spirited away so they couldn't be melted into cannon. The great State House bell traveled north by wagon and rested for months beneath the floorboards of Zion's Reformed Church here in Allentown before returning home in 1778. Decades later, antislavery reformers seized on its inscription—'Proclaim liberty throughout all the land'—and renamed it the Liberty Bell, turning a cracked colonial bell into an enduring emblem of freedom.
Moravian Cemetery
Bethlehem, PA · est. 1953
Consecrated by Count von Zinzendorf, this burial ground served Moravian Bethlehem from 1742 to 1910. In keeping with the community's belief that all are equal in death, only flat gravestones were permitted, laid in orderly rows without grand monuments. Here rest people of many nationalities and races — European settlers alongside Native American and African converts — a quiet testament to the Moravians' unusually inclusive spiritual vision.
Whitefield House - PLAQUE
Nazareth, PA · est. 1931
The Whitefield House traces its origins to 1740, when the famed revivalist George Whitefield acquired land in the Pennsylvania backcountry with the intention of founding a school for Black children. Moravian Brethren began the sturdy stone building, and after the Moravians purchased the tract in 1741 it served in turn as a family dwelling, a girls' boarding school, and a nursery for missionaries' children. Since the 19th century it has housed the Moravian Historical Society and Museum, preserving the memory of these early ventures.
