The Story

Charles Lockhart rose to become Pittsburgh's largest crude oil refiner in the 1860s, a period when the new petroleum industry was transforming western Pennsylvania. In 1874 his firm, Lockhart, Frew & Co., folded its seven refineries into John D. Rockefeller's Standard Oil, and Lockhart took a seat on the board of a combine that controlled the overwhelming share of American oil refining, transport, and marketing. One of his early offices once stood on this spot.

Patrick C. Boyle (1846-1920)

Oil City, PA · est. 2013

In the decades after the 1859 Drake Well strike, northwestern Pennsylvania's Oil Region became the crucible of the world's first petroleum boom, and Oil City sat at its heart. Patrick C. Boyle rose from the rough-and-tumble world of the oil scout to build trade papers—The Derrick and The Oil and Gas Journal—that told drillers, refiners, and investors what was happening across the fields. His publications gave a chaotic new industry a shared language and a national nervous system of prices and news.

Oil Well Supply Company

Oil City, PA · est. 1997

Founded near Oil City in 1878, the Oil Well Supply Company rose to become one of the leading makers of oil-field machinery and supplies, its equipment reaching drillers across the globe. At its height in the early 1900s the firm employed some 2,000 workers, and in 1930 it was absorbed as a subsidiary of the giant U.S. Steel. Its story traces the consolidation of scrappy oil-region enterprises into the era's great industrial combinations.

Joseph Reid Gas Engine Company

Oil City, PA · est. 1997

In the boomtown decades after Pennsylvania's Oil City became a hub of the world's first petroleum industry, Joseph Reid founded his gas engine works here in 1894. The company's rugged single-piston engine became a workhorse for pumping wells, shipped to oilfields around the globe until the firm shut its doors in 1939. It was a classic example of the specialized machine-building that grew up alongside the oil that made the region famous.

Jacob J. Vandergrift

Oil City, PA · est. 2001

When Jacob Vandergrift steamed into Oil City in 1861, Pennsylvania's oil boom was barely two years old and crude still moved the way freight always had — in barrels, by river and rail. Vandergrift saw a better way. Beginning in 1868 his firm laid pipe directly from the wells, and by 1877 he had consolidated much of the scattered pipeline business into his United Pipe Lines. In 1881 that network was folded into Rockefeller's Standard Oil empire, cementing the pipeline as the artery of modern petroleum.
