Historic Markers in Pennsylvania

Limestone Township, PA · est. 1919

John Jacob Leroy was among the settlers slain in the October 1755 violence along Penn's Creek, one of the first blows struck on Pennsylvania's frontier after General Braddock's defeat earlier that summer. His daughter Marie and a neighbor girl, Barbara Leininger, were carried west into captivity as far as the Muskingum in Ohio. After years among their captors the two young women escaped and made their way back to Philadelphia, later leaving one of the era's rare firsthand captivity accounts.

Charleroi, PA · est. 1999

John K. Tener embodied the Progressive Era's faith in energetic, reforming government. Governor of Pennsylvania from 1911 to 1915, he pushed through statewide primary elections and launched a state highway system just as the automobile was remaking American travel, while creating the Department of Labor & Industry and the very commission that would later plant markers like this one. An Irish immigrant who arrived at nine, he had earlier been a major-league pitcher and would go on to preside over baseball's National League.

Pittsburgh, PA · est. 2009

John M. Phillips was a Pittsburgh industrialist and engineer who turned his energies to a cause ahead of its time: protecting wild land and game for the public. He helped establish the Pennsylvania Game Commission and created the state game land system, known nationally as the Pennsylvania System and copied across the country. An early champion of the Boy Scout movement in Pennsylvania, he lived at this site.

North Strabane Township, PA · est. 1949

John McMillan arrived in southwestern Pennsylvania in 1775 as the region's first Presbyterian missionary, bringing organized religion and formal schooling to a rough frontier still being settled. He founded Hill Church in 1776 and went on to help establish Jefferson College and Western Theological Seminary, planting institutions of higher learning west of the mountains. After sixty years in the ministry he died in 1833 and lies in the churchyard he helped create.

Bellefonte, PA · est. 2000

John Montgomery Ward grew up in Bellefonte and became one of early professional baseball's most remarkable figures. Playing from 1878 to 1894, he pitched the sport's second perfect game in 1880 and later starred as a shortstop. Off the field he organized baseball's first players' union in 1885 and led the breakaway Players' League in 1890, challenging the owners' grip on the game.

Ridley Park, PA · est. 1967

Here stood the birthplace of John Morton (1724–1777), a Delaware County farmer and surveyor who rose to serve in the Continental Congress. When Pennsylvania's delegation was split over independence, Morton's vote—joining those of Benjamin Franklin and James Wilson—swung the colony behind the break with Britain. He went on to sign the Declaration of Independence, casting a decisive ballot at a hinge point of American history.

Lawrence Park Township, PA · est. 2004

In the anthracite-and-industry country of northwestern Pennsylvania, Erie's sprawling General Electric works were a union stronghold, and John Nelson rose to lead the United Electrical Workers' Local 506 through the volatile 1940s and 1950s. At the height of the postwar Red Scare, he was accused of Communist ties and became the first union leader GE dismissed, in 1953, even as his union fought for him in the courts. He died young at 42, his short life bound up in one of labor's hardest decades.

Philadelphia, PA · est. 2004

In the 1820s Johann Nepomuk Maelzel brought his traveling wonders to a Philadelphia exhibition hall, chief among them the Automaton Chess Player known as "The Turk," a mechanical marvel that appeared to play chess against all comers. A German-born inventor and showman, Maelzel is also credited with popularizing the metronome and crafting ear trumpets for the deaf Beethoven. His hall drew crowds eager to puzzle over the boundary between machine and illusion.

Pottsville, PA · est. 1982

From 1916 to 1928 this Pottsville house was home to John O'Hara, born in the town in 1905, who became one of America's most widely read novelists and short-story writers. He turned his native anthracite coal region into fiction, using its class tensions and social textures as the setting for several of his major works. O'Hara died in Princeton, New Jersey, in 1970.

Philadelphia, PA · est. 1998

John Page Nicholson fought in the Civil War and then devoted his life to remembering it. A meticulous scholar, he edited the two-volume Pennsylvania at Gettysburg and worked to preserve the battlefields at Gettysburg and Valley Forge. In 1888 he helped found a library and museum dedicated to the war he had lived through.

Philadelphia, PA · est. 1932

This Philadelphia site was home to two of colonial Pennsylvania's last royal-era officials. John Penn — grandson of the colony's founder William Penn — lived here in the years before the Revolution as the province's final colonial governor. The same house later belonged to Benjamin Chew, the last colonial chief justice, whose long life bridged the transition from proprietary rule to independent statehood.

Whitpain Township, PA · est. 2018

John Philip Boehm was a German schoolmaster turned minister who organized the scattered German Reformed settlers of colonial Pennsylvania into a genuine church. Between 1725 and 1740 he founded twelve congregations, each required to adopt a written constitution spelling out members' voting rights, rules of discipline, and the handling of money—an early experiment in self-governance on the frontier of the empire. He established his last congregation here in 1740 and lies buried beneath the church that bears his name.

Nanticoke, PA · est. 2016

John S. Fine rose from the coal country around Nanticoke through the courts to the governorship of Pennsylvania in the early 1950s. His administration modernized the state in ways large and small, from the first televised inauguration to its first permanent sales tax. Notably, he ended segregation in the Pennsylvania National Guard and opened the State Police to African American troopers, early steps toward integration in the postwar North.

South Mahoning Township, PA · est. 1950

John S. Fisher was born on an Indiana County farm in 1867 and served as governor of Pennsylvania from 1927 to 1931. His administration pushed an ambitious state building program, overhauled the commonwealth's fiscal system, and promoted the conservation of natural resources. He died in 1940, near the close of the era his reforms helped modernize.

Philadelphia, PA · est. 2021

John S. Trower built one of the most successful catering businesses of his day here in Philadelphia, becoming one of the wealthiest African Americans of the late nineteenth century. He turned his success into service, founding the Downingtown Industrial & Agricultural School and a building-and-loan association to help Black families become homeowners. A devout man, he gave generously to Baptist charities throughout his life.

Pittsburgh, PA · est. 1958

In 1786, when Pittsburgh was still a raw frontier town at the forks of the Ohio, the Berks County native John Scull printed the first edition of the Pittsburgh Gazette—the first newspaper published west of the Allegheny Mountains. From his home and print shop here, Scull carried the printed word into the trans-Appalachian West and took an active hand in the region's civic affairs. His paper endured, becoming the Post-Gazette in 1927.

St. Clair, PA · est. 2003

In the anthracite coal fields of Schuylkill County, miners worked one of the most dangerous jobs in 19th-century America, and John Siney rose to become one of the movement's pioneering voices. The Workingmen's Benevolent Association he helped lead, formed nearby in 1868, grew to 20,000 members and won some of the industry's first mine-safety laws and its first labor contract. Siney went on to head the Miners National Association and championed the Greenback Labor Party.

Tyrone Township, PA · est. 1948

In the 1830s a modest wagon-making shop stood near here, run by John Studebaker before he packed up and joined the great westward migration. His decision seeded a dynasty: in 1852 his sons opened a wagon works in Indiana that grew into the largest maker of horse-drawn vehicles in the world. When the age of the horse gave way to the motorcar, the Studebaker firm made the leap in 1897, becoming one of America's earliest automakers.

Stroudsburg, PA · est. 1999

By 1864 the Union relied on the draft to fill its armies, and even citizens exempt from service were urged to furnish substitute recruits. President Lincoln chose to lead by example, naming young John Summerfield Staples of Stroudsburg as his personal "representative recruit." After meeting the President at the White House on October 1, 1864, Staples served at Arlington, Virginia—one of fewer than 1,300 such symbolic enlistees.

Pittsburgh, PA · est. 2013

John T. Comes was among the most influential Catholic church architects of his day, shaping not just buildings but the very philosophy of how sacred spaces should be designed and adorned. A prolific writer and lecturer as well as a designer, the Pittsburgh resident left his mark across Pennsylvania and beyond, including St. Agnes here. His ideas guided a generation of ecclesiastical design in early twentieth-century America.

Shillington, PA · est. 2021

John Updike spent his first thirteen years in Shillington, and the small-town Pennsylvania world of his childhood — along with the encouragement of his mother, herself an amateur writer — shaped the sensibility that made him one of America's most celebrated authors. Over a 50-year career he won two Pulitzer Prizes and earned acclaim for his short stories and essays as well as his fiction. He is best remembered for the "Rabbit" quartet, which followed an ordinary American man across four decades of national change.

Philadelphia, PA · est. 1990

John Coltrane lived in this Strawberry Mansion neighborhood house from 1952 to 1958, during the formative years when a young saxophonist was becoming one of the most important voices in jazz. He would go on to weave African and Indian musical elements into a searching, spiritual style that first startled listeners before it reshaped the music entirely. Philadelphia was the crucible where his restless artistry took form.

Mount Pleasant, PA · est. 1951

John W. Geary was born in this Westmoreland County town in 1819 and lived one of the most far-flung public careers of his generation. He served as the first mayor of San Francisco in the Gold Rush year of 1850, was appointed territorial governor of a bitterly divided "Bleeding Kansas" in 1856, rose to major general in the Civil War, and finally served as governor of Pennsylvania from 1867 until his death in 1873.

New Cumberland, PA · est. 1995

John W. Geary lived one of the most eventful public lives of 19th-century America. He served as a colonel in the Mexican War, became the first postmaster and first mayor of San Francisco during the Gold Rush, and was appointed governor of the volatile Kansas Territory during the "Bleeding Kansas" crisis over slavery. He then won distinction as a Union major general in the Civil War before serving two terms as governor of Pennsylvania from 1867 to 1873. His home stood just east of here in New Cumberland.

Waynesboro, PA · est. 1955

In 1797 John Wallace Jr. platted the streets of a new town in the fertile Cumberland Valley and named it Waynesburg to honor General Anthony Wayne, the fiery Revolutionary War commander known as "Mad Anthony." The name was changed to Waynesboro in 1831 to avoid confusion with other Pennsylvania towns of similar name. The stone portion of Wallace's own house still stands nearby, a survivor of the founding era.

East Hanover Township, PA · est. 1947

John Walter worked alongside Jacob Albright in the early 1800s to organize what became the Evangelical Church, a German-language revival movement among the Pennsylvania Dutch. Though he died young in 1818 at only twenty-seven, Walter was remembered as a powerful preacher and hymn writer who compiled the first songbook for the fledgling denomination. He lies buried in this cemetery, near the communities his preaching stirred.

Philadelphia, PA · est. 1998

John Wanamaker opened his first Philadelphia store in 1861 and, in 1876, unveiled a "new kind of store" that helped invent modern retailing. He pioneered the fixed one-price system and the money-back guarantee, treating customers with a fairness that reshaped how Americans shopped. As U.S. Postmaster General he championed rural free delivery and introduced the commemorative postage stamp.

Titusville, PA · est. 2009

Long before his name graced college football's most famous award, John Heisman was a boy in the oil-boom town of Titusville, playing rough games near his father's cooperage. He grew into one of the sport's great innovators, championing the forward pass, the center snap, the scoreboard, and dividing games into quarters — reforms that also made a brutal game safer. As a founder of the American Football Coaches Association, he helped turn a chaotic pastime into an organized national sport.

Franklin, PA · est. 1982

John Chapman, the wandering nurseryman remembered as Johnny Appleseed, tended orchards along French Creek near here between 1797 and 1804 before moving on to Ohio. Records show he kept a nursery in this area and another near Warren, planting apple trees ahead of the advancing frontier. Born in Massachusetts in 1774, he died in Indiana in 1845, already a folk legend.

Pittsburgh, PA · est. 2004

Before he became a Pro Football Hall of Famer, Pittsburgh native Johnny Unitas honed his game close to home, quarterbacking the semi-pro Bloomfield Rams to a Steel Bowl Football Conference championship in 1955. Signed by the Baltimore Colts in 1956, he led them to the 1958 NFL title in a game often called the greatest ever played. His rise from sandlot football to legend is woven into Pittsburgh's sporting lore.

Windber, PA · est. 1999

Before he swung through the jungle as Hollywood's Tarzan, Johnny Weissmuller was one of the greatest swimmers who ever lived, refining the 'American crawl,' setting 67 world records, and winning five Olympic gold medals in 1924 and 1928. He spent part of his childhood in Windber before his family moved to Chicago, and he returned for occasional visits in later life. His dozen Tarzan films for MGM and RKO between 1932 and 1948 made him a global star.

Unity Township, PA · est. 1946

This sturdy 1815 house, sometimes called Kingston House, sheltered the boyhood of William F. Johnston, who served as governor of Pennsylvania from 1848 to 1852. His term fell squarely in the era of the state's great public-works push, when canals and early railroads were knitting the commonwealth together and moving people and freight across the mountains. Built by his father in an admired colonial style, the home preserves a corner of early Pennsylvania's rising political and civic life.

Springfield Township, PA · est. 1948

In the decades after statehood, taverns like Arthur Johnston's were the gas stations, inns, and news exchanges of the American road. Licensed in 1827 with the present stone-and-timber building raised in 1831, this house fed and lodged travelers moving along the Pittsburgh-Mercer road in western Pennsylvania. Its fortunes were tied to the nearby Springfield Furnace, an iron works that fired up after 1837 and drew traffic to the crossroads.

Adams Township, PA · est. 1947

On the night of May 31, 1889, the South Fork Dam gave way, sending a wall of water down the valley toward Johnstown in one of the deadliest disasters in American history. The remnants of the failed dam can still be seen a short distance from this marker, a silent witness to the catastrophe. The flood killed thousands and became a national symbol of both tragedy and the era's uneasy relationship between industry, wealth, and public safety.

Johnstown, PA · est. 2005

On May 31, 1889, the earthen South Fork Dam above Johnstown gave way, sending a thirty-five-foot wall of water and debris roaring fourteen miles down the valley into the busy steel town. In minutes it destroyed more than 1,600 homes and took 2,209 lives, making it one of the deadliest disasters in American history. In its aftermath, a wave of aid poured in from across the country, and Johnstown slowly rebuilt.

Johnstown, PA · est. 1999

After decades of catastrophic flooding, Johnstown got a massive engineered answer: a concrete-paved channel project built by the U.S. Army Corps of Engineers between 1938 and 1943. Running 9.2 miles along the city's three rivers, it became the nation's second-largest flood control work of its kind and reflected the New Deal-era shift toward a major federal role in local flood protection. It held back the waters for decades until the devastating flood of record in 1977.

Springville Township, PA · est. 2001

Born in 1840 to parents who had escaped slavery, Jonathan Jasper Wright grew up in Springville and went on to become the first Black lawyer admitted to the bar in Pennsylvania. He stood with Frederick Douglass in the fight for the vote and legal equality, and in 1870, during Reconstruction, he was elevated to the South Carolina Supreme Court—the first African American to sit on a state's highest court. His rise from a runaway slaves' son to the bench marked a breathtaking, if fragile, moment of possibility.

California, PA · est. 1995

Joseph "Jock" Yablonski spent his life in the coalfields as a United Mine Workers official fighting to improve conditions for miners. After losing a reform bid for the union presidency in 1969, he, his wife Margaret, and their daughter Charlotte were assassinated in their home on December 31 in a killing traced to union leadership. The outrage over the murders fueled a reform movement that swept new leaders into the UMW in 1972.

Philadelphia, PA · est. 2009

In the decades before the Civil War, Philadelphia was home to a thriving community of free Black Americans who built their own institutions of self-help and reform. Joseph Cassey, a prosperous barber and real-estate dealer, extended rentals and loans to Black and white customers alike, while he and his wife Amy founded benevolent and intellectual societies. Amy Cassey was also active in the Female Anti-Slavery Society, part of a network of women driving the abolitionist cause.

St. Thomas Township, PA · est. 1960

Joseph Armstrong settled this Franklin County land in the 1730s, on the contested edge of Pennsylvania's frontier. He served in the colonial Assembly and rose as a militia captain, and his home became a ranging station in 1757 for troops during the French and Indian War. It served the same purpose during Pontiac's War of 1763–64, when Native resistance again swept the backcountry.

Philadelphia, PA · est. 2000

For a year or so after 1815, this Philadelphia house sheltered Joseph Bonaparte — Napoleon's elder brother and the deposed king of Naples and later Spain — as he began his long American exile following the collapse of the Napoleonic empire. In these rooms gathered Bonapartist refugees and French émigrés, a small colony of the defeated regime finding footing in the young republic. Joseph would go on to build a grand estate at Point Breeze in New Jersey and live in America for years before returning to Europe.

Wyalusing Township, PA · est. 1928

This marker honors Joseph Elliot, a Revolutionary War soldier of the embattled Wyoming Valley frontier. He fought at Trenton on the night of December 25, 1776, and by tradition was given a sword by George Washington for his bravery. He survived the Wyoming Massacre of 1778 — breaking free at the Bloody Rock and swimming the Susquehanna with a bullet in his shoulder — and later, at the 1782 Battle of Lime Hill, helped rescue captured children.

Bern Township, PA · est. 1947

Joseph Hiester rose from Revolutionary War soldier—captured and held on a British prison ship—to a long career in public life, serving in Congress and then as governor of Pennsylvania from 1820 to 1823. A son of the Pennsylvania German community, he lived at the Hiester Mansion here in Berks County. The property later became part of the county welfare farm.

Philadelphia, PA · est. 2005

At the dawn of the 20th century, Philadelphia-born architect Joseph Huston built Oaks Cloister as his own home and studio, folding into its Tudor design the architectural details and artwork of the very craftsmen he would soon marshal for a far grander project. Trained in the influential Philadelphia firm of Furness and Evans before striking out on his own in 1895, Huston went on to design the Pennsylvania State Capitol in Harrisburg, a Beaux-Arts landmark whose lavish decoration reflected the collaborative artistry glimpsed in his private residence.

Northumberland, PA · est. 1947

Fleeing political and religious persecution in England, the chemist and Unitarian thinker Joseph Priestley settled in Northumberland from 1794 to 1804 and built a home and laboratory beside the river. Famous as an early isolator of oxygen, he spent his American years continuing his scientific and theological work in this quiet Susquehanna town, which now preserves the site as a museum.

Point Township, PA · est. 1947

The English chemist and Unitarian theologian Joseph Priestley, celebrated for isolating oxygen, made his home in Northumberland from 1794 to 1804 after leaving England. His riverside house and laboratory, now preserved as a memorial and museum, became a base for his scientific inquiry and dissenting faith during his final decade in America.

Northumberland, PA · est. 1963

From 1794 to 1804 this house on the Susquehanna was home to Joseph Priestley, the English clergyman and chemist celebrated for isolating oxygen and other gases. A political and religious radical, Priestley fled England after mobs burned his home for his sympathies with the American and French revolutions, and he rebuilt his life and laboratory in the new republic. Here in Northumberland he continued his experiments and helped seed a scientific tradition in his adopted country.

Oil City, PA · est. 1997

In the boomtown decades after Pennsylvania's Oil City became a hub of the world's first petroleum industry, Joseph Reid founded his gas engine works here in 1894. The company's rugged single-piston engine became a workhorse for pumping wells, shipped to oilfields around the globe until the firm shut its doors in 1939. It was a classic example of the specialized machine-building that grew up alongside the oil that made the region famous.

Bristol, PA · est. 2008

Joseph Ridgway Grundy rose from Bristol's textile mills to become one of the most powerful figures in Pennsylvania and national Republican politics. An industrialist, publisher, and banker, he founded the Pennsylvania Manufacturers' Association in 1909 and championed pro-business, low-tax, high-tariff policies, briefly serving as U.S. Senator in 1929–1930. His fortune still funds a foundation, library, and museum bearing his name.

West Pennsboro Township, PA · est. 1951

Joseph Ritner, a Berks County–born farmer of German stock, served as Pennsylvania's governor from 1835 to 1839. His lasting achievement was defending and putting into practice the Free School Act of 1834, which established Pennsylvania's public school system over fierce opposition from those who resented the tax. He is buried in this cemetery, having died in 1869 near Carlisle.

Lancaster, PA · est. 2006

In the mid-1700s, Lancaster sat on the edge of the British colonies' expanding frontier, a bustling inland hub where traders outfitted expeditions toward the Ohio country and beyond. Joseph Simon, a Jewish merchant, built a far-reaching network of trade and land ventures that reached as far as the Mississippi, and when the Revolution came he helped arm the Continental cause. His home doubled as one of the earliest gathering places for Jewish worship west of Philadelphia.

Great Bend Township, PA · est. 1947

In the years before 1830, the young Joseph Smith spent time in this part of the Susquehanna Valley, where — according to Latter-day Saint tradition — much of the translation work that produced the Book of Mormon was carried out. The site, a few miles from this marker, became one of the formative locations in the origins of a distinctly American religious movement. The land is preserved by the church that grew from Smith's work.

Oakland Township, PA · est. 1948

In the late 1820s a young Joseph Smith lived in this stretch of the Susquehanna valley, where his wife Emma's family had roots. Here, at a house nearby, he carried out much of the work he described as translating the golden plates into the Book of Mormon, the founding scripture of the movement he would lead. An infant son of his is buried in this cemetery.

McVeytown, PA · est. 1947

Joseph T. Rothrock was born on this spot on April 9, 1839, and grew up to become the father of Pennsylvania's state forest system. At a time when the state's woodlands had been stripped bare by unchecked logging, he championed reforestation, scientific forestry, and organized fire control, helping launch the state forests that still cover the mountains around him. He is remembered as one of the founders of the American conservation movement.

West Chester, PA · est. 1952

Joseph Trimble Rothrock lived in this West Chester house from 1876 until his death in 1922, during the decades when Pennsylvania's forests were being stripped bare by logging and fire. A physician turned botanist and reformer, he championed the idea that the state should own and manage forests as a public trust, and he became Pennsylvania's first forestry commissioner. His campaigns for fire control, reforestation, and scientific management laid the groundwork for the state forest system.

Chambersburg, PA · est. 2005

In the decades after the Civil War, Chambersburg was home to Joseph Winters, a Black inventor whose ingenuity turned a common danger into a solvable problem. In 1878 he patented a wagon-mounted fire escape ladder with a hose conductor, then improved on it the next year — innovations that helped firefighters reach upper stories and save lives. Before that, Winters had risked his own freedom and safety aiding those escaping slavery on the Underground Railroad.

Pittsburgh, PA · est. 1996

Before Major League Baseball opened its doors to Black players, some of the game's greatest talent thundered through the ballparks of the Negro leagues — and few hit harder than Josh Gibson. His career began at Pittsburgh's Ammons Field in 1929, and through the 1930s and '40s he powered the Homestead Grays and Pittsburgh Crawfords with a bat that reportedly launched some 800 home runs. Denied the big-league stage in his lifetime, he was elected to the Baseball Hall of Fame in 1972, a quarter century after his early death.

Haverford Township, PA · est. 1947

Joshua Humphreys, the naval architect who designed the frigate USS Constitution — the legendary "Old Ironsides" — made his home from 1803 to 1838 at the Pont Reading House standing opposite this marker. His heavy, fast, over-built frigates gave the young United States Navy warships that could outfight or outrun anything of comparable size. The house itself grew by stages between 1683 and 1813, a layered piece of early Pennsylvania architecture.

Corry, PA · est. 2008

After oil was struck near Titusville, the Downer Oil Works rose nearby in 1862, and chemist Joshua M. Merrill made it a laboratory of refining. He devised an illuminating oil safer than kerosene for railroads, steamships, and factories, then pioneered deodorized lubricants that opened world markets in the late 1860s. His work earned recognition at Philadelphia's 1876 Centennial Exhibition.

Moon Township, PA · est. 2008

Joshua Meeks took up arms as a militia captain during the American Revolution and stayed to help build the new republic on the western Pennsylvania frontier, petitioning in 1787 to create Allegheny County. A farmer by trade, he opened his home to serve as a fort in times of danger, a polling place for elections, and a schoolhouse for the community. Through these acts he wove the habits of citizenship into the fabric of a frontier settlement.
