Shadyside Iron Furnace

Pittsburgh, Allegheny County, Pennsylvania

Marker Inscription

Built on lowlands here in 1792. Birth of the iron industry in the Pittsburgh region. It made stove and grate castings. Closed about a year later due to lack of ore and wood.

Erected by Pennsylvania Historical and Museum Commission

The Story

On these Monongahela lowlands in 1792, just as the young republic was pushing industry west of the Alleghenies, a small charcoal-fired furnace began casting stoves and grates. It is remembered as the first stirring of what would become Pittsburgh's defining trade. The venture proved fragile, though: within roughly a year the nearby supplies of iron ore and hardwood for charcoal ran short and the fire went cold.

Why it matters

This brief, failed furnace marks the literal beginning of the iron and steel industry that would make Pittsburgh the forge of industrial America.

Roslyn Place

Pittsburgh, PA

On a short cul-de-sac in Pittsburgh's Shadyside neighborhood, Roslyn Place is paved not with brick or asphalt but with tens of thousands of creosote-treated wooden blocks, laid in 1914. Wood-block paving briefly caught on in American cities because it muffled the clatter of horses and early automobiles, but nearly all of it has since rotted away or been paved over. Roslyn Place endures as one of the very few wooden streets left in the United States.

1st Drive-In Filling Station

Pittsburgh, PA ยท est. 2000

In December 1913, on this Pittsburgh corner, the Gulf Refining Company opened what is generally recognized as the first purpose-built drive-in gas station โ€” a facility designed from the ground up to sell gasoline, oils, and lubricants to a public newly in love with the automobile. Before it, motorists bought fuel in cans from hardware stores and pharmacies. Its success set off a nationwide building boom, as rival oil companies raced to line American roads with thousands of filling stations.

Andrew Carnegie (1835-1919)

Pittsburgh, PA ยท est. 1996

Andrew Carnegie arrived from Scotland as a poor immigrant boy and rose to become the steel magnate whose Pittsburgh mills helped power America's industrial age. Preaching a "Gospel of Wealth" that held the rich were duty-bound to give their fortunes away, he funded more than 2,500 libraries and endowed institutions devoted to education and world peace. His philanthropy reshaped access to books and learning across the country and beyond.

Standard Chemical Company

Pittsburgh, PA ยท est. 2018

Founded in Pittsburgh in 1913 by brothers J.J. and Joseph Flannery, the Standard Chemical Company was the first commercial producer of radium in the United States โ€” the earliest chapter of what would become the nuclear industry. Extracting the rare element from carnotite ore was painstaking, costly work at the frontier of science. In 1921 Marie Curie herself, radium's co-discoverer, visited the laboratory and was presented with a full gram of the element to support her research.
