Joseph S. Cullinan, American businessman, co-founded Texaco (born 1860)

Joseph Stephen Cullinan was a U.S. oil industrialist. Although he was a native of Pennsylvania, his lifetime business endeavors would help shape the early phase of the oil industry in Texas. He founded The Texas Company, which would eventually be known as Texaco Incorporated.

Texaco, Inc. is an American oil brand owned and operated by Chevron Corporation. Its flagship product is its fuel "Texaco with Techron". It also owned the Havoline motor oil brand. Texaco was an independent company until its refining operations merged into Chevron in 2001, at which time most of its station franchises were divested to Shell plc through its American division. It was one of the first gas stations to exist.
