Westinghouse Atom Smasher
Forest Hills, Allegheny County, Pennsylvania
Marker Inscription
The world's 1st industrial Van de Graaff generator was created by Westinghouse Research Labs in 1937 as an early experiment with atomic energy. The 5-story pear-shaped structure is located here. The company remained active in establishing US leadership in nuclear power.

The Story
In 1937, on the eve of the atomic age, Westinghouse Research Labs raised a five-story, pear-shaped tower here to house the world's first industrial Van de Graaff generator—an early machine for accelerating particles and probing the atom. Built by one of America's great electrical companies, it marked private industry's entry into what would become nuclear science. Westinghouse went on to play a central role in establishing American leadership in nuclear power.
Why it matters
The Atom Smasher captures the moment when American industry began investing in atomic research, foreshadowing the nation's postwar dominance in nuclear energy and the transformation it brought to science, power, and warfare.
The story behind this marker
AI contextThe era
In the 1930s, western Pennsylvania was one of the beating hearts of American industry. Around Pittsburgh, steel mills, electrical works, and research laboratories crowded the river valleys, and the suburban borough of Forest Hills sat within that dense industrial belt. This was a region that turned scientific ideas into machines and machines into products the whole country used.
The decade was also the eve of a scientific revolution. Physicists around the world were probing the atom, trying to understand the tiny nucleus at its center and the enormous energies locked inside. Most of that work happened in universities. What made this spot unusual was that a private company decided the atom was worth its own money and its own building.
By 1937 the Great Depression still gripped much of the nation, yet the great electrical firms kept investing in research, betting that tomorrow's fortunes lay in discoveries not yet made. Raising a five-story tower to accelerate particles was exactly that kind of bet — expensive, uncertain, and pointed straight at the future.
People & events
The tower built here housed a Van de Graaff generator, a machine that builds up an enormous electric charge and uses it to fling atomic particles at high speed. Scientists used such devices to break into the nucleus of the atom — which is how the structure earned its enduring nickname, the "Atom Smasher."
What set this one apart, according to the marker, was that it was the first Van de Graaff generator built for industrial research rather than for a university lab. It was created by Westinghouse Research Labs, part of one of America's foremost electrical companies, and its distinctive pear shape rose five stories above the ground — an unmistakable landmark and a statement of ambition.
The experiments carried out here were early steps into atomic energy, at a moment when almost no one yet knew where that road would lead. The company that built the tower went on to remain deeply involved in nuclear work, helping the United States take a leading role in the development of nuclear power in the decades that followed.
Its place in the American story
This tower marks the moment American private industry stepped directly into atomic research. Before this, probing the nucleus was largely the work of universities and government-backed laboratories. Here, a company put its own resources behind the atom — a signal that the science had commercial as well as intellectual value.
That instinct would prove far-reaching. Within a decade the world would enter the atomic age in the most dramatic way imaginable, and in the years afterward the same expertise that industry had been quietly building turned toward generating electricity from nuclear reactions. The country's postwar leadership in nuclear power did not appear from nowhere; it grew from investments like this one.
So a quiet suburban site becomes a hinge in a much larger American story — the story of how a nation's laboratories, factories, and companies together made the United States a world leader in a technology that would reshape science, energy, and warfare alike.
If you visit
Come here thinking about scale and ambition. The idea of a private company raising a five-story tower simply to accelerate invisible particles is startling even now, and standing on the ground where it happened helps you feel how bold a gamble it was in 1937.
The marker frames this as the birthplace of industrial atomic research in America, so let it reset your mental picture of the atomic age. It didn't begin only in famous desert labs or wartime headlines — it also began in ordinary American industrial towns, in the offices and yards of electrical companies chasing the future.
If you're building a road trip around western Pennsylvania's industrial heritage, this fits naturally alongside the region's steel and manufacturing history. It's a reminder that this corner of the country didn't just make the machinery of the 20th century — for a moment, it reached for the very building blocks of matter itself.

Pioneer Short-Wave Station
Forest Hills, PA
In the early 1920s the airwaves were a frontier, and Pittsburgh's Westinghouse Electric was at its leading edge — home of KDKA, one of the nation's first commercial broadcasting stations. On this Forest Hills ground in 1923 the company opened a laboratory to push transmission farther than anyone thought practical, guided by engineer Frank Conrad, whose backyard tinkering had helped launch broadcasting itself. The work here proved that short waves, bouncing off the upper atmosphere, could carry a signal clear across oceans — a discovery that shrank the world.
Radio Station KDKA
Turtle Creek, PA · est. 1990
On the night of November 2, 1920, from a rough studio at Westinghouse's East Pittsburgh Works, KDKA went on the air with returns from the Harding-Cox presidential race — widely recognized as the world's first commercial radio broadcast. Within months the station was regularly airing music, sports, talks, and special events, giving listeners a reason to buy receivers and inventing the daily rhythm of broadcast programming. A makeshift experiment quickly became an industry.
George Westinghouse
East Pittsburgh, PA · est. 1948
George Westinghouse was one of the towering inventors of America's industrial age, credited with the railroad air brake and some four hundred other patents. From his base in Pittsburgh he championed alternating-current electricity, the system that won the 'War of the Currents' and made it possible to transmit power across long distances. The company he founded turned his ideas into an industrial empire that helped electrify the modern world.
Frederick Ingersoll (1874-1927)
West Mifflin, PA · est. 2019
At the dawn of the 20th century, Americans were flocking to a new kind of attraction—the electrically lit amusement park—and Frederick Ingersoll was one of its great inventors. From Pittsburgh he designed Figure-8 coasters and other rides that appeared across the country, and in 1905 he launched his dazzling, brightly illuminated Luna Parks in the Oakland neighborhood, sparking imitators worldwide. He also built some of Kennywood's earliest rides, including the Old Mill and the park's first Racer coaster.
