The Story
In 1883 a group of Pittsburgh entrepreneurs, including John Ford and John Pitcairn, launched the nation's first commercially successful plate glass works, with its first plant at Creighton along the Allegheny River. Plate glass was a demanding, capital-intensive product that European makers had long dominated, and breaking that hold helped make Pittsburgh a center of American glassmaking. The firm grew into a diversified industrial giant, becoming PPG Industries in 1968.
Why it matters
The company's success marked American industry catching up to and surpassing European manufacturing in a high-skill trade, part of the Gilded Age surge that made Pittsburgh a workshop of the nation.
The story behind this marker
AI contextThe era
In the decades after the Civil War, American industry went looking for things Europe still did best — and set out to make them better and cheaper at home. This was the Gilded Age, an era of furnaces and railroads and fortunes, and no place embodied it more completely than Pittsburgh, where the rivers, the coal, and the will to build turned a river city into a workshop for the nation.
Plate glass was one of those stubbornly European products. Making large, flat, clear sheets of glass was demanding, capital-hungry work, and for a long time the best of it came from across the Atlantic. Earlier American attempts had struggled against that dominance.
The founding of a plate glass company in 1883, with its first plant upriver at Creighton, belongs squarely to that moment of American industry reaching for a high-skill trade it did not yet own.
People & events
The enterprise was launched in 1883 by John Ford, John Pitcairn, and other partners who were willing to bet capital on a difficult product. What set their venture apart was not merely that they made plate glass, but that they made it pay — it became the first commercially successful plate glass manufacturer in the United States.
That success was not guaranteed. Plate glass demanded large plants, skilled labor, and patient investment, and the market was already supplied by established makers abroad. Building a profitable American works meant mastering the process and the business at the same time.
The first plant stood at Creighton, along the Allegheny, while the company kept its office in the heart of Pittsburgh's business district. From those beginnings the firm grew far beyond a single product, diversifying over the decades until, in 1968, it took the name by which it is known today: PPG Industries.
Its place in the American story
The story of this company is a small, sharp version of a much larger American story: the moment the United States stopped importing a sophisticated manufactured good and started making it competitively at home. Breaking the European hold on plate glass was exactly the kind of victory that defined Gilded Age industry.
It also helped cement Pittsburgh's identity. The city is remembered for steel, but its genius was broader — a concentration of fuel, capital, skill, and nerve that could take on almost any heavy, high-skill trade. Glass was part of that portfolio, and this firm was part of what made the region a center of American glassmaking.
The long arc from a single 1883 plant to a diversified modern corporation is the arc of American manufacturing itself: start by matching the world at one hard thing, then grow into many.
If you visit
You won't find the original works here — the marker sits in downtown Pittsburgh, near where the company kept its office, while the first plant was upriver at Creighton. That gap is its own lesson: the decisions and the money lived in the city; the furnaces and the labor lived along the river.
Stand among the downtown buildings and picture the business district of the 1880s, when a new company was gambling that it could out-make Europe at a trade Europe thought it owned. The modern city around you, and the global corporation the firm became, are the answer to whether the gamble paid off.
It makes a natural stop on a walking tour of Pittsburgh's industrial and business heritage. Let it prompt you to look up — at the glass in the windows around you — and remember that making it well was once a hard-won American achievement.

Work Accidents and the Law (1910)
Pittsburgh, PA · est. 2008
In 1910, reformer Crystal Eastman published a painstaking study of industrial conditions in Allegheny County, tallying 526 workplace deaths in a single year. Part of the sweeping Pittsburgh Survey, her work put hard numbers to the human cost of America's factories, mills, and mines at the height of the industrial age. The findings helped drive accident-prevention programs and the first workers' compensation laws.
John Scull (1765-1828)
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.
Westinghouse Electric Corporation
Pittsburgh, PA · est. 1986
In the 1880s a fierce rivalry raged over how to deliver electric power, and George Westinghouse bet on alternating current. Founding his company in Pittsburgh in 1886, he built the motors, generators, and transformers that let electricity travel over long distances rather than only a few blocks. That gamble on AC would light cities and power factories far from any generating plant.
McClurg Iron Foundry
Pittsburgh, PA · est. 2016
Established in 1804, the McClurg Iron Foundry was Pittsburgh's first air foundry, casting metal in a young industrial city perched at the gateway to the West. During the War of 1812 it forged cannons and ammunition, much of it destined for the American fleet that would contest control of Lake Erie. In 1835 the site achieved another milestone, producing the first locomotive steam engine built west of the Allegheny Mountains.
