Sylvania Electric Products
Emporium, Cameron County, Pennsylvania
Marker Inscription
During WWII, produced critical electrical components including vacuum tubes for proximity fuzes, a key military device that improved the precision of artillery shells. Founded in 1907, the workforce was composed of primarily women, prompting Colliers to call Emporium "Girls Town USA.” The former Sylvania Club here was the home of one of the company’s original investors, lumber baron Henry Auchu. The factory operated on Poplar St. until 1990.

The Story
Founded in 1907 in the small mountain town of Emporium, Sylvania Electric grew into a national name in vacuum tubes and electronics. During World War II its workers—largely women—produced vacuum tubes for the proximity fuze, a device that let artillery shells detonate near their targets and dramatically improved accuracy. The reliance on a female workforce led Collier's to dub Emporium "Girls Town USA," and the Poplar Street plant ran until 1990.
Why it matters
The plant shows how even remote rural towns became vital nodes in the wartime arsenal, and how women's labor powered the precision technology that helped decide battles.
The story behind this marker
AI contextThe era
Founded in 1907, Sylvania Electric took root in Emporium, a small town tucked into the mountains of north-central Pennsylvania. This was hard-country industry, far from the big coastal manufacturing centers — the kind of place where a single plant could become the heartbeat of an entire community. Over the decades it grew into a national name in vacuum tubes and electronics, the delicate glass components that made early radios, and later so much more, come alive.
Then came the Second World War, and with it a total mobilization of American industry unlike anything the country had seen. Factories large and small were pulled into the war effort, and remote towns suddenly found themselves producing components on which battles could turn. Emporium was one of them.
The war also transformed the American workforce. With so many men in uniform, women stepped into industrial jobs in enormous numbers, keeping the nation's factories running. At Sylvania's Emporium plant, that shift was so pronounced that the workforce was made up primarily of women — a fact that would come to define the town's wartime identity.
People & events
The plant's most consequential wartime work was precise and almost invisible: it produced vacuum tubes for the proximity fuze. This was a key military device — a fuze that let an artillery shell or projectile sense its target and detonate at just the right moment, near the target rather than only on direct impact. It dramatically improved the accuracy and effectiveness of artillery, and it was among the most closely guarded technologies of the war.
That such demanding, high-stakes components came from a small mountain town, made largely by women, is the heart of this story. Their careful, skilled labor turned Emporium into a genuine node in the wartime arsenal. The reliance on that female workforce drew national notice; Collier's dubbed the town "Girls Town USA," a nickname that captured just how thoroughly women powered the place.
The marker also nods to the company's roots. The former Sylvania Club here was the home of one of the company's original investors, the lumber baron Henry Auchu — a reminder that the fortunes of Pennsylvania's timber country helped seed the electronics enterprise that followed. The factory ran on Poplar Street until 1990, closing a chapter that had lasted more than eight decades.
Its place in the American story
Emporium's story reframes how we picture the "arsenal of democracy." It was never only the great shipyards and aircraft plants of the big cities. Victory also depended on countless smaller factories in out-of-the-way towns, each supplying a specialized piece of the whole. A remote plant turning out proximity-fuze tubes was as essential in its way as any famous assembly line.
It is also a landmark of women's history. The proximity fuze was celebrated as one of the war's most important technological advances, and here the precision work behind it rested largely on women's hands. "Girls Town USA" was more than a catchy headline; it documented a real and often overlooked truth about who actually built America's wartime technology.
And it traces the long arc of American industry — from a company born in 1907, through its transformation into a wartime supplier, to a plant that endured until 1990. That span links the era of early electronics to the modern age, all through one factory in one small town.
If you visit
Emporium's mountain setting is part of the story, so take it in. It can be surprising to stand in such a quiet, scenic corner of Pennsylvania and realize that critical wartime technology was made right here. That contrast — remote town, world-shaping work — is exactly what makes the site memorable.
As you read the marker, hold onto the human image behind the technology: a workforce made up largely of women, performing exacting labor on components meant for the front lines. "Girls Town USA" isn't just a slogan to smile at; it's an invitation to remember the people, mostly women, who kept this plant running when the country needed it most.
If you're touring Pennsylvania's industrial and World War II history, this is a rewarding stop precisely because it's off the beaten path. Look toward Poplar Street, where the factory operated until 1990, and consider the full life of the place — from a lumber baron's investment in 1907 to the wartime work that earned a small town a national nickname.

Lock Haven, PA · est. 2024
What began as the Taylor Brothers company in 1927 became an American aviation giant after William T. Piper bought the firm and moved it to Lock Haven in 1937. At its height Piper Aircraft employed more than 2,000 people and built nearly 77,000 general-aviation planes here, including some 20,000 of the iconic yellow J-3 Cub. During World War II, thousands of Cubs were adapted into L-4 Grasshoppers that trained pilots and flew reconnaissance for the U.S. Army.
Cameron County
Emporium, PA · est. 1982
Cameron County was pieced together in 1860 from four neighboring counties and named for U.S. Senator Simon Cameron, the powerful Pennsylvania politician who would soon serve as Lincoln's first Secretary of War. Its seat, Emporium, took shape in the 1860s in a landscape of deep forests, and lumbering drove the early economy. Flagstone quarried in the county was later chosen for the Tomb of the Unknown Soldier at Arlington.
Austin Flood Disaster
Keating Township, PA · est. 1994
On September 30, 1911, the concrete dam of the Bayless Pulp and Paper Company — built only two years earlier, nearly fifty feet high and 534 feet long — gave way, hurling a wall of water and debris down Freeman Run into the towns of Austin and Costello. At least 78 people were killed and the mill towns were devastated. Pennsylvania's second-worst single-dam disaster, it spurred a 1913 state law to regulate dam construction.
Leidy Natural Gas Boom
Leidy Township, PA · est. 1995
In the winter of 1950, wildcatter Dorcie Calhoun ignored expert opinion and drilled deep into the hills of Leidy Township in search of natural gas. On January 8 his well struck gas at more than 5,600 feet, briefly gushing an estimated 15 million cubic feet a day. The strike made national news and set off a frenzy: within months more than thirty companies and independent operators were drilling across the township, chasing the boom before the field's production wound down.
