Pittsburgh Grease Plant
Pittsburgh, Allegheny County, Pennsylvania
Marker Inscription
Long a major producer of lubricating grease for industry, transportation, and the military. In WWII, supplied 5,000,000 pounds of "Eisenhower grease," vital to the war effort. Founded here, 1885, by Grant McCargo. After 1929, part of Standard Oil (NJ); operated until 1999.

The Story
Founded in Pittsburgh by Grant McCargo in 1885, this plant became a major producer of the lubricating grease that kept American industry, railroads, and machinery running. Its most storied contribution came during World War II, when it supplied five million pounds of "Eisenhower grease" deemed vital to the war effort. Absorbed into Standard Oil of New Jersey after 1929, the works kept operating until 1999 — more than a century of quiet but essential industrial labor.
Why it matters
The plant is a monument to the unglamorous industrial backbone of American power, the kind of specialized manufacturing that lubricated both the nation's factories and the machinery that won a world war.
The story behind this marker
AI contextThe era
By the late nineteenth century, Pittsburgh had become one of the engines of American industry, a city defined by steel, machinery, and relentless production. But heavy industry runs on more than muscle and iron — it runs on the humble, essential products that keep metal moving against metal without grinding itself to ruin. Lubricating grease was one of those unglamorous necessities.
When this plant was founded in 1885, the nation was in the thick of its industrial transformation. Factories, railroads, and an ever-growing fleet of machines all demanded reliable lubrication, and specialized manufacturers rose to supply it. A grease works might never make headlines, but without it the wheels — quite literally — could not turn.
The plant's long life, from the 1880s through the end of the twentieth century, spans nearly the entire arc of modern American industry: the railroad age, two world wars, the rise of the great oil corporations, and the slow decline of old-line manufacturing.
People & events
The plant was founded here in 1885 by Grant McCargo, an entrepreneur who saw opportunity in a product most people never think about. His works grew into a major producer of the lubricating grease that industry, transportation, and the military all depended upon.
Its most storied chapter came during World War II. The plant supplied five million pounds of what was known as "Eisenhower grease" — a product deemed vital to the war effort. In a conflict decided in no small part by machinery and logistics, keeping engines, weapons, and vehicles running was itself a form of service, and this Pittsburgh works answered the call at massive scale.
The business did not stay independent. After 1929 it became part of Standard Oil of New Jersey, one of the towering names of the American oil industry. Under that ownership the plant kept working, continuing its quiet, essential production until it finally closed in 1999 — well over a century after McCargo first opened its doors.
Its place in the American story
This plant is a monument to the industrial backbone that made American power possible. We tend to remember wars and industry through their dramatic images — the battles, the skyscrapers, the assembly lines — but victory and prosperity also depended on countless specialized products made by workers whose names history rarely records.
The wartime story is especially telling. The Allied effort in World War II was, in large part, a triumph of production and logistics, and something as ordinary as grease was genuinely vital: without lubrication, the machines that won the war would seize and fail. Five million pounds from a single plant is a reminder of the sheer scale of the industrial mobilization.
The plant's absorption into Standard Oil of New Jersey also mirrors a larger national story — the consolidation of independent works into the great corporate giants of the oil age. From founding to closure, this site traces the full life cycle of American industry.
If you visit
Don't expect drama here — expect to appreciate the unglamorous. This is a place to stand and think about all the essential work that goes on out of sight, the manufacturing that keeps a nation's machinery moving without ever asking for credit.
Let the marker reframe how you see the industrial landscape around Pittsburgh. Once you know that a plant like this quietly supplied millions of pounds of grease — including a wartime product deemed vital to victory — the old works and rail lines of the region take on new meaning.
Fit this stop into a broader tour of Pittsburgh's industrial heritage. It pairs naturally with the region's better-known steel and oil history, offering a reminder that the story of American industry is written not only in blast furnaces and skyscrapers, but in the specialized, century-long labor of places most travelers would otherwise drive right past.

Mooncrest
Carnegie, PA · est. 2004
In 1943, with the nation's factories running full-tilt for the war, the federal government threw up planned housing like Mooncrest to shelter the workers who kept the arsenal fed. Its residents crossed the river to the Dravo Corporation, turning out armor plate, munitions, and ships for the fight overseas. After the war the Air Force ran the community briefly before the little homes passed into private hands in the 1950s.
Dravo Corporation Shipyard
Neville Township, PA · est. 1995
On this island in the Ohio River just below Pittsburgh, the Dravo Corporation turned a peacetime engineering firm into one of the arsenal of democracy's most unlikely powerhouses. Its inland shipyard mass-produced Landing Ship Tanks—the ungainly, flat-bottomed LSTs that carried tanks, trucks, and troops straight onto hostile beaches. Using assembly-line techniques Dravo pioneered, this yard and four others hundreds of miles from any ocean built two-thirds of the Navy's entire LST fleet, floating them down the rivers to the sea. More than 16,000 workers here produced 145 of the vessels between 1943 and 1945.
Charles Martin Hall
Pittsburgh, PA · est. 1998
Here in 1888 the young inventor Charles Martin Hall's method of producing aluminum by electrolysis was first put to commercial use by the Pittsburgh Reduction Company — the firm that would grow into industrial giant Alcoa. Before Hall's breakthrough, aluminum was a rare and costly novelty; his process made the lightweight metal cheap and abundant. What began as a Pittsburgh experiment turned aluminum into a staple of the modern age.
Stephen C. Foster
Pittsburgh, PA · est. 1976
Stephen Foster, born near Pittsburgh on Independence Day in 1826, became the first American to make a living writing popular songs. His melodies for the traveling minstrel stage carried tunes like his best-known ballads into parlors across the nation, helping invent an American commercial songwriting trade. Fame did not spare him; his health and fortunes faded, and he died poor in New York in 1864.
