The Story
When Welsh immigrant Robert M. Jones arrived in 1848, he opened the first slate quarries around Bangor, drawing on skills carried from the slate country of Wales. The industry boomed, and the region became one of the world's leading producers of slate for roofing and for the writing slates and pencils once found in every schoolhouse. Waves of Welsh workers followed, giving the area a distinct heritage that endured for generations.
Why it matters
The Bangor slate belt shows how immigrant know-how built a world-leading American industry, and its school slates literally furnished the classrooms of a rising, literate nation.
The story behind this marker
AI contextThe era
The middle of the nineteenth century was an age of migration and industry. Across the Atlantic, the crowded coal and slate districts of Britain sent skilled workers streaming toward America, and the young United States, hungry for both labor and raw materials, drew them in. This marker's story opens in 1848, squarely in that current, though it reaches forward into the industrial boom of the Reconstruction and Gilded Age.
Northeastern Pennsylvania proved a natural landing place. Beneath the hills around Bangor lay thick beds of high-quality slate — the same dark, fine-grained stone that had made parts of Wales famous. For a Welshman who knew the trade, it must have looked like home ground with the ground itself full of promise.
What followed was the transformation of a rural corner of Northampton County into a busy quarrying district, its fortunes tied to stone split from the earth by hand and skill.
People & events
The story begins with Robert M. Jones, a Welsh immigrant who arrived in 1848 and started the region's slate quarrying industry. He carried with him something more valuable than tools: the deep, inherited knowledge of a people who had worked slate for generations in Wales.
Slate is not simply dug; it is read and split. A skilled quarryman knows how the stone will cleave into thin, strong sheets — the craft that turns rough rock into roofing and writing surfaces. Jones brought that expertise, and where he led, others followed.
Waves of Welsh workers came to the area in the years after, giving the slate belt a distinct heritage — in names, in chapels, in the very rhythm of the work. Together they built something that outgrew any single quarry: a district that became a major world center for slate.
Its place in the American story
Two products carried this region's stone into everyday American life. The first was roofing slate, which sheltered homes, churches, and public buildings across a rapidly growing country. The second was more intimate — the writing slates and slate pencils that once sat on the desk of nearly every schoolchild.
Think of what that second product meant. In an era before cheap paper, a durable slate and pencil were how a generation learned its letters and sums. Stone quarried from these Pennsylvania hills helped furnish the classrooms of a nation determined to educate itself.
The marker also tells a larger American truth: that immigrant skill, not just immigrant labor, built the country's industries. A single Welshman's craft became a world-leading enterprise — a pattern repeated in mills, mines, and workshops across the United States.
If you visit
Bangor sits in the hilly country of northeastern Pennsylvania's slate belt, and the landscape still carries the industry's fingerprints. Look for old quarry pits, spoil heaps of broken gray-blue stone, and above all the roofs — slate roofs on older buildings are the region's signature.
Let the Welsh heritage guide your eye. Place-names, historic chapels, and community memory in this area all echo the immigrants who made the slate belt what it was. The town wears its origins if you take a moment to notice.
This is a rewarding stop on a drive through Pennsylvania's industrial and immigrant history. Stand at the marker, picture a schoolroom full of children with slates in hand, and consider how far a single stone could travel — from these hillsides to desks and rooftops across the country.

Nazareth, PA · est. 2000
German-born Christian Frederick Martin founded his guitar-making firm in 1833 and, in 1838, moved it from New York City to the Moravian community around Nazareth, building a small shop here in 1859. Martin's workshop pioneered designs — the X-braced flat-top and later the powerful Dreadnought — that would define the sound of the American acoustic guitar. Today C. F. Martin & Co. ranks among the oldest surviving musical instrument makers in the world.

Bethlehem, PA · est. 2006
Born in Germany in 1728, David Tannenberg emigrated in 1749 to the Moravian religious community at Bethlehem, part of the wave of German-speaking settlers who shaped colonial Pennsylvania. Trained under organ builder Johann Gottlob Klemm at nearby Burnside Plantation, he went on to craft nearly fifty pipe organs prized for their tonal richness and beauty. He was still at work when he died in York in 1804.
David Thomas
Catasauqua, PA · est. 2001
David Thomas carried a hard-won secret across the Atlantic from Wales: how to smelt iron using abundant, slow-burning anthracite coal rather than scarce charcoal. Settling in the Lehigh Valley, he built the Crane Iron Works, widely credited as the first anthracite iron furnace to succeed both technically and as a business. His breakthrough transformed eastern Pennsylvania's hard-coal region into an industrial powerhouse and earned him the title "father of the American anthracite iron industry."
Slate Industry
Slatington, PA · est. 2002
The region around Slatington grew into one of the largest slate-producing centers in the United States after Welsh entrepreneur William Roberts spotted slate near a local barn in 1844. He and fellow Welsh immigrants opened a cluster of quarries, including the vast "Big Franklin" and the "Williams" quarry famous for making school slates. Their work helped fuel the popularity of slate roofing across America in the later 19th century.
