Interesting Historical Facts
Sinclair Oil Corporation is an American petroleum corporation, founded by Harry F. Sinclair on May 1, 1916 as the Sinclair Oil and Refining Corporation by combining the assets of 11 small petroleum companies. Originally a New York corporation, Sinclair Oil reincorporated in Wyoming in 1976. The corporation's logo features the silhouette of a large green dinosaur.
Sinclair has long been a fixture on American roads with its dinosaur logo and mascot, an apatosaurus (Brontosaurus).
During September 1919, Harry F. Sinclair restructured Sinclair Oil and Refining Corporation, Sinclair Gulf Corporation, and 26 other related entities into Sinclair Consolidated Oil Corporation. In 1932, this new entity was renamed Consolidated Oil Corporation. In 1943, it was renamed Sinclair Oil Corporation.
At the Chicago World's Fair of 1933-1934, Sinclair sponsored a dinosaur exhibit meant to point out the putative correlation between the formation of petroleum deposits and the Age of Dinosaurs. The exhibit included a two-ton animated model of a brontosaurus. The exhibit proved so popular it inspired a promotional line of rubber brontosaurs at Sinclair stations, complete with wiggling heads and tails, and the eventual inclusion of the brontosaur logo. Later, inflatable dinosaurs were given as promotional items, and an anthropomorphic version appeared as a service-station attendant in advertisements. Some locations have a life-size model of the mascot straddling the building's entrance.
