Industry & Invention

Hastings, PA · est. 2007

From 1924 to 1926, the United Mine Workers of America brought traveling "Labor Chautauquas"—programs of education and entertainment—to the bituminous coal towns of western Pennsylvania, and Hastings drew the largest crowds in 1925. Under District 2 president John Brophy, these gatherings featured nationally known speakers alongside local performers. They won national press attention and admiration from Progressive-era reformers.

Abilene, TX

In the 1880s, Abilene was a young railroad town on the West Texas plains, and lawyer Henry Sayles arrived in 1886 to practice alongside his eminent legal-scholar father and manage property for Galveston investors. Around 1889 he and his wife Hattie built this finely detailed Queen Anne home on what was then a nearly empty avenue. As president of the Abilene Land and Improvement Company, Sayles helped shape the surrounding neighborhood that still bears the family name.

Victoria, TX

German immigrant George Herman Hauschild came to Victoria after his 1866 marriage and, having built a prominent business, opened an opera house here in 1894. Occupying the top two floors above the family's music store, the theatre hosted vaudeville, plays, and silent films under the management of his son H.J. Hauschild. As "talking pictures" won over audiences, the opera house closed during the 1930s.

Mineral County, NV

Hawthorne was laid out in 1880 by Carson and Colorado Railroad president H. M. Yerington as a division point, named for pioneer lumberman William A. Hawthorne rather than its planned name of Millbrae. The town seesawed through Nevada's county-seat rivalries—taking the Esmeralda seat from Aurora in 1883, losing it to Goldfield in 1907, and becoming Mineral County's seat in 1911. Its fortunes turned again in the late 1920s when the Navy, after a disastrous eastern munitions explosion, chose Hawthorne for a huge ammunition depot, commissioned in 1930.

Sealy, TX

Daniel Haynes arrived in the new railroad town of Sealy in 1881, and in 1885 he invented both a process and a machine for making a felted, non-tufted cotton mattress. Sold nationwide under his trademark, the mattresses became so identified with the town that when Haynes sold his patents in 1906 the buyer took the name Sealy. Haynes opened a new factory on this site in 1909, and it remained one of the town's leading industries until 1976.

Granbury, TX

This native-stone building went up in the early 1870s as an early home of the Granbury post office, erected by postmaster James C. Haynes. Later owners included postmaster Thomas Burns and newspaperman Thomas Ewell, who wrote an early history of Hood County. Offices, stores, and cafes filled the structure until its 1975 restoration.

Sealy, TX

Built in 1901–1902 for H. Schumacher in Sealy, this Queen Anne residence passed in 1906 to Richard H. Haynes, who with his father founded the Haynes (Sealy) Mattress Company in 1909. Confectioner F. J. Felcman bought the house in 1927 and enlarged it, and it stayed in his family into the 1990s. Its projecting gable, wood shingles, stained glass, and jigsawn brackets make it a fine example of late-Victorian domestic style.

Churchill County, NV

Hazen sprang up in 1903 as a rough-and-tumble camp housing laborers on the federal Newlands irrigation project, one of the first reclamation efforts to green the Nevada desert. When the railroad to Tonopah arrived in 1905 and the Southern Pacific built a roundhouse and depot the next year, the town of hotels, saloons, and brothels boomed—alongside a reputation for lawlessness that included the 1905 lynching of 'Red' Wood. Fire nearly wiped it out in 1908, and the town named for Civil War general William B. Hazen never fully recovered.

Tyler, TX

When Union naval blockades choked off imported medicine during the Civil War, the Confederacy turned to home-grown remedies. Near the mineral waters of Headache Springs, one of only nine Confederate medical laboratories—and the sole one west of the Mississippi—produced medicines and whiskey for the government. Workers gathered native herbs like poke root, snakeroot and mullein and combined them with mineral salts into what the marker aptly calls the medicines of desperation.

Rocksprings, TX

Founded in Missouri in 1898, the American Angora Goat Breeders' Association moved to Texas in 1924 and settled in Rocksprings in 1926, the heart of the state's mohair country. Its headquarters keeps the complete national registry of Angora goats along with portraits of breeders and champion animals.

Dalhart, TX

The XIT was one of the largest ranches on earth, born of an 1882 deal in which out-of-state investors led by Chicago's Farwell brothers built the massive Texas capitol in Austin and took three million acres of Panhandle land in payment. Fenced by some 6,000 miles of barbed wire and stretching 200 miles across ten counties, it saw its first herd delivered in 1885, when trail boss Abner Blocker scratched the famous "XIT" brand in the corral dust. Dalhart still honors the ranch's cowboys with the "empty saddle" monument, dedicated in 1940.

Cuero, TX

Built around 1880 for David H. Heaton, proprietor of Cuero's first drugstore, this colonial revival home reflects the confident prosperity of a South Texas town coming into its own in the late nineteenth century. In 1924 civic leader Charles G. Breeden bought the house and remodeled it into its present classical form—two-story porch, colossal box columns, lunette dormers, and a porte cochere—only to die the following year. It has stood since as one of Cuero's most recognizable landmarks.

Trinity, TX

This Victorian residence was built in Huntsville in 1900 for J.E. Coldwell by builder Elias Jones, and bought in 1919 by grocer and butcher Walter Gibson Hedrick, whose family kept it until 1978. Moved to Trinity that year and later enlarged, it retains its second-floor turret with fish-scale shingling and gingerbread-trimmed porch. It preserves the ornamental domestic architecture of turn-of-the-century Texas.

Galveston, TX

Raised in 1878 during Galveston's heyday as the great port of Texas, this Italianate commercial block passed through a parade of wholesale grocers, ship chandlers, and steamship men — including Heinrich Mosle, who opened a direct trade route between Galveston and Latin America. Its stuccoed masonry, hood molds, and pilasters, scored to mimic cut stone, reflect the confident mercantile architecture of the Gilded Age waterfront. An ornamental cornice was lost, likely to the catastrophic 1900 storm.

Houston, TX

Founded in 1915 as only the second Church of Christ congregation in Houston, this church built its first home in 1916 and, less than a decade later, commissioned noted architect Alfred C. Finn for a Renaissance Revival sanctuary. Anchoring the Houston Heights neighborhood, the congregation went on to plant new churches across the region and support foreign missions.

Waller, TX

German-born Heinrich Leverkuhn came to Texas in 1857 and served as a foragemaster for the Confederate army during the Civil War before opening a store in Hockley. In 1878 he took up farming and ranching in the community now called Macedonia, where he ran a cotton gin, syrup mill, and blacksmith shop. He helped found the Macedonia Methodist Church and McPherson School and, across two marriages, raised fourteen children.

Roma, TX

German-born builder Heinrich Portscheller reached the Rio Grande shortly after the Civil War, when Roma stood as the river's westernmost port and its twin commercial towns hummed with trade. Drawing on brickmaking skills passed down through his family, he opened a brickyard and designed load-bearing brick buildings on both banks of the river, marked by pressed and molded brick, classical columns, iron balconies, and richly detailed cornices. His work still defines much of Roma's National Historic Landmark downtown; in 1894 the railroad boom drew him to Laredo, where he built and worked until his death in 1915.

Highland Township, PA

In the wooded hills of Clarion County, the stone stack of the Helen Furnace still stands as a relic of Pennsylvania's antebellum iron boom. Built in 1845, this was a cold-blast charcoal furnace—an early industrial technology that smelted local iron ore using heat drawn from surrounding hardwood forests. It was one of dozens of such furnaces that dotted the county between roughly 1829 and 1867, when the region earned the nickname "The Iron County" for the sheer density of its ironworks.

Giddings, TX

Born in Giddings in 1885, the daughter of a bank president, Helen Knox was among the few women to earn an athletic letter, in tennis, at the University of Texas. By 1927 she was managing women's accounts at Chase National Bank in New York and had become a recognized writer on banking. She led the National Association of Bank Women as president in the mid-1940s and chaired the finance drive to restore Robert E. Lee's home.

Austin, TX

Robert Ziller, descendant of a prominent pioneer Austin family, and his wife Helena built this Mediterranean Revival home in 1937 on a bluff above Blunn Creek and the Colorado River. They called the property Edgecliff Gardens, practicing organic gardening and creating a haven for animals. Designed by Lee M. Smith, the stucco house features a prominent front gable, a cantilevered window, and dramatic ornamental ironwork attributed in part to Weigl Ironworks.

Amarillo, TX

Erected in 1968, this monument marks the centennial of helium's discovery in the sun's atmosphere and celebrates Amarillo's role as capital of the helium industry. Its four "time columns" were packed with books, documents, and artifacts, then sealed in a helium atmosphere to be opened after 25, 50, 100, and 1,000 years. The Texas Panhandle had produced commercial helium from natural gas since 1918, with processing plants near Amarillo from 1929 and vast quantities stored underground for industry, science, the military, and the space program.

Maysville, KY

Mason County was the only major hemp-producing county in Kentucky outside the Bluegrass, its 1810 crop worth $70,000. By the 1830s Maysville trailed only Louisville in finished hemp goods, its ropewalks—long buildings for spiral-winding fiber—turning out hundreds of thousands of pounds of rope a year. Statewide, hemp was Kentucky's largest cash crop until 1915, when cheap imported jute finally broke the market.

Hemphill, TX

Sabine County organized the town of Hemphill in 1858, naming it for Texas Supreme Court Justice John Hemphill and moving the county seat to the county's center on land surveyed from the Slaughter tract. A post office, courthouses, a bank, and Sabine Valley University followed, while the nearby Knox Sawmill drove steady growth into the twentieth century. When the mill burned in 1937 and postwar migration pulled people toward cities, Hemphill's population declined, though it remains the seat of Sabine County government.

Henderson, TX

Founded in 1843 as the seat of newly created Rusk County, Henderson took its name from Republic of Texas statesman James Pinckney Henderson, later the state's first governor. Land was donated by W. B. Ochiltree and General James Smith, the "Father of Henderson," with lots set aside for churches and schools. A devastating 1860 fire, postwar railroads, and above all the 1930 discovery of the vast East Texas oil field — which swelled the population from 2,000 to 10,000 in months — shaped the town.

Athens, TX

Long before Europeans arrived, Caddoan peoples worked the rich clay deposits of this region into fine pottery, drawing on resources the land offered in abundance. The modern industry began in 1857 when Levi S. Cogburn, from a Georgia family of potters, started making cups, saucers, and plates in Athens. After his death the trade revived in 1885 under M. K. Miller and his sons, whose Athens Pottery Company launched a run of tile, brick, and pottery plants that made Henderson County a ceramics center.

Victoria, TX

John W. Henderson, an Arkansas native who prospered in Victoria through insurance, ranching, farming, and real estate, bought this property with his wife Minna in 1909. After relocating an older home from the lot, they built a stately Classical Revival residence designed by Sam H. Dixon and built by Fred Urban. Later it passed to auto dealer and civic leader W.E. Franz, whose widow lived here into the 1950s.

Galveston, TX

The mercantile house of William Hendley & Co., founded in 1845, helped drive Galveston's rise as a great port, launching a packet line of fast sailing ships and building ever-larger vessels for the Gulf trade. Between 1855 and 1858 the firm erected this three-story Greek Revival commercial row of four granite-trimmed buildings, whose rooftop cupola became a lookout post for both Confederate and Federal forces during the Civil War. After the war it housed banks, engineers, and merchants as the block stayed at the center of Galveston commerce.

Abilene, TX

In 1915 Abilene's First Baptist pastor Millard Jenkens envisioned a hospital that would treat everyone, paying or not, and his congregation raised $35,000 to make it real. Opened in 1924 as the West Texas Baptist Sanitarium with 52 beds and a nursing school, the hospital nearly foundered in the Depression until Thomas and Ida Hendrick paid off its debt and financed a new wing in 1936 — earning it their name. Wing after wing followed, and in 1971 it became Hendrick Medical Center, the regional hospital it remains today.

Amarillo, TX

In 1875 Henry B. Sanborn became the Texas sales agent for Joseph Glidden's newly patented barbed wire, arriving as ranchers and farmers fought over whether the open range should be fenced. Sanborn bought thousands of acres to prove barbed wire could enclose vast holdings, and in 1881 partnered with Glidden to build the famous Frying Pan Ranch, ringed by 120 miles of wire. His promotion of the Amarillo townsite later earned him the title "Father of Amarillo."

Amarillo, TX

Built in 1903, this Amarillo building is tied to Henry Bradley Sanborn, one of the men most responsible for the city's very existence. Sanborn, who made his fortune promoting barbed wire, helped relocate and establish Amarillo on higher, better-drained ground in the 1880s, earning him a reputation as a founder of the town. By the early 1900s his name was woven through the young Panhandle city's growth. A building raised for him marks the confidence of a frontier settlement maturing into a permanent community.

Fredericksburg, TX

Descended from a Lutheran pastor sent by the Adelsverein to serve German settlers, Henry Basse and his brother Hugo ran a cement works whose 'Basse block' became a favored building material in the Hill Country. Between 1918 and 1920 Henry built this house as a showcase of that product and his success. Its Prairie School lines and two-story columned porch make it a fine local example of the style.

Amarillo, TX

A New York native, Henry Bradley Sanborn came to Texas in 1875 as sales agent for barbed-wire inventor Joseph Glidden, and together they founded the vast Frying Pan Ranch in 1881 to prove that wire fencing could tame the open range. When a rival site won the county seat, the undaunted Sanborn developed his own townsite nearby, luring residents there after heavy rains flooded the original and later securing the rail connections that guaranteed Amarillo's future. On this spot stood his home, offices, stables for matched coach horses, and even a deer park.

Galveston, TX

Built in 1893 as rental property, this raised Galveston cottage became an early asset of brothers August and Henry Henck, who launched a real estate business on the island in 1901. Henry made it his home in 1898, and it stayed in the family until 1974. Its Eastlake porch frieze, elaborate balustrade, and side porch mark the flourishing Victorian building era of a booming Gulf port.

Wichita Falls, TX

Missouri-born Henry C. Luecke reached Texas around 1890 and opened a blacksmith shop at this Wichita Falls corner in 1903. There he designed and built the Wichita Gang Plow, patented in 1905, a multi-furrow implement whose three control levers gave farmers unusual maneuverability. It sold widely across the region until the steam tractor rendered such horse-drawn plows obsolete.

El Paso, TX

Ohio native Henry C. Trost became one of the most prolific architects of the American Southwest, making El Paso his base and its skyline his canvas. Drawing on Louis Sullivan, Frank Lloyd Wright, and the Mission Revival, he forged a regional style suited to the desert climate, designing landmarks such as the Hotel Cortez, El Paso High School, the Paso del Norte Hotel, and Bassett Tower. He died in 1933, but the firm he founded with his brothers carried on into the 1950s.

Doylestown Township, PA · est. 1998

At the turn of the twentieth century, Henry Chapman Mercer helped lead the American Arts and Crafts movement from the quiet county seat of Doylestown. A trained archaeologist who feared industrialization was erasing the tools of everyday life, he both revived handmade ceramic tile and amassed a sprawling collection of preindustrial American implements. Between 1908 and 1916 he poured three fantastical reinforced-concrete buildings — his home Fonthill, his tile works, and his museum — that still stand as some of the boldest early experiments in that material.

East Huntingdon Township, PA · est. 1946

Here in the Pennsylvania countryside near West Overton, one of America's most formidable industrialists began life in a modest homestead tied to the Overholt distilling family. Henry Clay Frick rose from these rural roots to build a coke and steel empire, partnering with Andrew Carnegie and turning the region's coal into the fuel that fired the nation's furnaces. The preserved Overholt home now interprets both the whiskey-making family that raised him and the Gilded Age fortune he went on to amass.

Pittsburgh, PA · est. 1946

Henry Clay Frick rose to become one of the titans of Gilded Age Pittsburgh, building a fortune in coke — the refined coal that fed the blast furnaces of the steel age — before helping lead Andrew Carnegie's steel empire. As chairman of Carnegie Steel, his hard line against organized labor helped ignite the violent 1892 Homestead Strike, in which workers and Pinkerton agents fought a deadly pitched battle. Frick later turned his wealth toward philanthropy and art collecting.

Fredericksburg, TX

Fredericksburg native Henry Cordes, born in 1861, had this limestone home built in 1893, beginning as a three-room dwelling accompanied by a smokehouse, tankhouse, and stone cistern. The stonework shows the fine craftsmanship of the German masons who gave the Hill Country its distinctive architecture. Cordes worked for years at the Reliance Roller Mill and the Stein Ice House and raised three children here with his wife Emma.

Corsicana, TX

Florida-born Henry G. Damon served in the Confederate army and spent part of the Civil War as a prisoner before starting over in Corsicana in 1873. There he practiced law and founded the Texas Loan Agency, an early real estate mortgage firm that helped finance the region's industrial growth from this building through the 1890s. An active civic booster and prohibitionist, Damon helped shape the young oil town's development.

Philadelphia, PA · est. 1984

The economist Henry George was born on this Philadelphia spot on September 2, 1839, and went on to write "Progress and Poverty," a book that sold in the millions and made him one of the most widely read thinkers of the Gilded Age. He argued that society should tax the value of land — a value the community creates — rather than the fruits of individual labor and capital. His "single tax" ideas sparked reform movements at home and abroad before his death in New York in 1897.

Matador, TX

A North Carolinian who came to Texas in 1854 and served in the Confederate army, Henry Harrison Campbell turned to droving cattle before founding the Matador Ranch at Ballard Springs in 1879. Within three years the operation ran 40,000 head across 100,000 owned acres and 1.5 million more of free range, and in 1882 it was sold to a Scottish syndicate, the Matador Land & Cattle Company. Campbell stayed on as superintendent, led the effort to organize Motley County in 1891, and served as its county judge — his wife Elizabeth famously refusing a dugout and insisting on a proper house.

Dudley, MA

In 1846 Henry Hale Stevens founded a linen manufactory along the French River in Dudley, Massachusetts, building it into one of the few enduring producers of fine linen and toweling in nineteenth-century America. Stevens Linen Works drew on the region's abundant water power and a growing workforce to weave goods at a time when linen was overwhelmingly imported from Europe. This weathered millstone, set out as a memorial, is a tangible relic of that early industrial enterprise and of the man who put a small New England mill town on the manufacturing map.

Boerne, TX

Built on Boerne's Main Street in the late 1800s, this modest building housed the real estate, insurance, and private banking offices of Henry J. Graham. Born in Brazil, Graham reached Boerne in the 1870s and became a community leader who served Kendall County as both tax assessor and deputy sheriff. His old office later held a succession of businesses and was moved more than once before coming to rest here in 1984.

Pittsburgh, PA · est. 1994

Henry J. Heinz began in 1869 with a humble product — bottled horseradish sold from a Pittsburgh garden — and built it into one of the world's great food empires within two decades. In an era of adulterated and mislabeled food, Heinz staked his brand on purity, selling his condiments in clear glass so buyers could see exactly what they were getting. He paired shrewd, theatrical advertising with unusually generous treatment of his workers, reshaping both how Americans ate and how businesses sold to them.

Orange, TX

The son of German immigrants, Henry Jacob Lutcher built a successful lumber business in Pennsylvania before he and partner G. Bedell Moore, drawn by the vast pine forests of southeast Texas, relocated part of their operation to Orange in the 1870s. There he raised a large sawmill, bought up timberland, and introduced improved milling techniques that other operators adopted. His support for deep-water ports at Sabine Pass, Orange, and Beaumont, and for new rail lines, helped knit the region into the national economy; his widow Frances Ann continued his philanthropy after his 1912 death.

Orange, TX

Born in Orange in 1887 into the Lutcher lumber fortune, Henry Jacob Lutcher Stark joined the family empire after graduating from the University of Texas in 1910 and, though he lived modestly, was ranked Texas's wealthiest man by the 1920s. He diversified into banking, real estate, oil, and manufacturing while serving 24 years on the UT Board of Regents, twelve of them as chair. An avid collector of art and rare books, he founded a philanthropic foundation and gave generously to universities, the Stark Museum of Art, and local causes from sports teams to a boys' band.

Fort Worth, TX

Georgia-born Henry W. Williams built his fortune in Fort Worth as founder of the H.W. Williams Wholesale Drug Company and a prominent local banker. Between 1907 and 1909 he raised this Colonial Revival residence, distinguished by a Corinthian-columned portico and a broad veranda. For a century it has passed among leading area families whose homes reflected the community's aspirations.

Bethlehem, PA · est. 1995

Henry Noll was a Bethlehem Steel laborer whose extraordinary output—said to be 45 tons of pig iron loaded in a single day in 1899—became the human centerpiece of Frederick W. Taylor's influential book, Principles of Scientific Management. Disguised as "Schmidt" in Taylor's writings, Noll's willingness to work for a raised daily wage of $1.85 helped Taylor argue that careful measurement could multiply productivity. The story shaped how factories, offices, and armies would organize work for a century.

Liberty, TX

Louisiana native Henry O. Ager settled in Liberty, Texas, as a druggist in 1884 and, after meeting Bridgett Garrity at the 1893 Chicago World's Fair, married and built this classical revival home in 1905. Beyond his drugstore, Ager served as county clerk, school board president, and bank president, while his family later opened the town's Ager Theatre. Built of cypress with a wraparound gallery, the house has remained in the family for more than a century.

Rouseville, PA · est. 1996

Henry R. Rouse traded the schoolroom and the Warren County legislature for the booming oil fields of northwestern Pennsylvania, where new leaseholders were making fortunes almost overnight. On April 17, 1861, he was among nineteen people killed when the Little & Merrick well exploded and burned; mortally injured, he dictated a will that left generously for local roads and the poor. The village had just been renamed Rouseville in his honor, and among its residents was a young Ida Tarbell, who would grow up to become the oil industry's most famous critic.

Galveston, TX

Built in 1859 in Galveston, this elegant residence became known for its art treasures and lavish craftsmanship — hand-carved plaster ceilings, eight marble fireplaces, carved rosewood interiors, and tall wall mirrors, with much of the material imported from Switzerland. Its plaster-over-brick exterior and refined design reflected the wealth and taste of the antebellum South. It was long associated with Henry Rosenberg, the Swiss immigrant banker and merchant who became one of Galveston's leading citizens.

Marble Falls, TX

This Hill Country settlement grew up around the water mill Noah Smithwick built in 1855; when he left for California in 1861 the mill kept running. A. M. Cox raised this two-story building in 1874, a store below and, from 1876, a Masonic lodge above—the Henry Thomas Lodge, which minister Henry Thomas had relocated from nearby Turkey Bend. The lodge gained the upper floor through Cox's will, a small monument to frontier fraternal life.

Seguin, TX

A young immigrant from Wichmannshausen, Germany, Henry Troell settled near Seguin before 1860 and, after service in the Confederate Army, parlayed a freighting business into a web of local enterprises. His dam and grist mill on this site grew into something remarkable for a small Texas town — he added hydroelectric generation and, in the 1890s, gave the city its first municipal water and electric systems.

Bessemer, AL

Henry Wilson Sweet (1902–1990) was a mid-20th-century Alabama public servant whose career touched the economic and civic life of Jefferson County, Bessemer, and the state. As a county commissioner he helped secure the land that brought the University of Alabama's medical center to Birmingham, and as director of the state docks he oversaw a period when the Port of Mobile reached its highest national ranking. He also ran for governor in 1954 and led national and international port and civic organizations.

Plainfield Township, PA · est. 1974

About 1800, William Henry II built a firearms works in this Northampton County valley, part of a noted gunmaking family whose craftsmanship armed Americans across generations. Rifles and muskets made here supplied troops in the War of 1812, and the Henry name endured on shotguns produced as late as 1904. The factory was one of the small, skilled arms shops that gave the young nation its firepower.

Jackson Township, PA

In the wooded ridges of Perry County stood Pandemonium, one of the small industrial hamlets that sprang up across 19th-century Pennsylvania wherever water, bark, and hides could be brought together. Henry's tannery turned oak and hemlock bark into the tannin that cured leather, an essential trade before synthetic chemistry. When the bark ran out and demand shifted, the town emptied, leaving only foundations and the tannery ruins behind.

Rosebud, TX

Sam G. and Estella Henslee built this modified Victorian residence in 1907, when Rosebud was a growing Central Texas town. An early businessman and city council member, Sam Henslee helped lead the community's development, and the home remained in his family until 1944. Its shingle-style details, Doric-columned porch, and diamond-patterned gable mark it as a showplace of its day.

Bay City, TX

Built in 1905 by the Alamo Lumber Company, this Victorian-era home was designed by architect Henry Hensley for his brother Alexander with one clever aim: to catch a Gulf Coast breeze from any direction. Its unusual octagonal plan gave the central living room eight doors and not a single window, four of them opening onto wraparound porches. It later passed to the Gusman family, who kept it for generations.

East Pennsboro Township, PA · est. 2004

Patented in 1869 by Joseph G. Henszey and built the same year by Philadelphia's Continental Bridge Co., this wrought iron bowstring arch truss is an early survivor of the bridge-building boom that followed the Civil War. It first carried traffic over Trout Creek in Slatington, was relocated in 1900 to span Ontelaunee Creek, and in 2002 moved again to Summerdale to carry pedestrians. Few of its kind remain.
