Amoco Corporation, originally Standard Oil Company (Indiana), was a global chemical and oil company that was founded in 1889 around a refinery located in Whiting, Indiana, United States.
It later absorbed the American Oil Company, founded in Baltimore in 1910 and incorporated in 1922 by Louis Blaustein and his son Jacob. Amoco merged with BP in December 1998 forming BP Amoco, later renamed to BP, though the Amoco name continued at most stations until 2002.
The firm’s innovations included two essential parts of the modern industry, the gasoline tanker truck and the drive-through filling station. Its headquarters were located in the Amoco Building (now the Aon Center) in Chicago, Illinois.
