Teapot Rock: Teapot Rock is a distinctive sedimentary rock formation in Natrona County, Wyoming that lent its name to a nearby oil field that became notorious as the focus of a bribery scandal during the Presidential administration of Warren G. Harding, the Teapot Dome scandal.  The site was listed on the National Register of Historic Places in 1974.

Warren G. Harding: Warren Gamaliel Harding (November 2, 1865 – August 2, 1923) was the 29th President of the United States, serving from March 4, 1921, until his death in 1923.  At the time of his death, he was one of the most popular presidents, but the subsequent exposure of scandals that took place under his administration, such as Teapot Dome, eroded his popular regard, as did revelations of an affair by Nan Britton, one of his mistresses.  In historical rankings of the U.S. presidents, Harding is often rated among the worst.

Pan American Petroleum and Transport Company: The Pan American Petroleum and Transport Company (PAT) was an oil company founded in 1916 by the American oil tycoon Edward L. Doheny after he had made a huge oil strike in Mexico.  Pan American profited from fuel demand during World War I, and from the subsequent growth in use of automobiles.  For several years Pan American was the largest American oil company, with holdings in the United States, Mexico, Colombia and Venezuela.  In 1924 Pan American was involved in the Teapot Dome scandal over irregularities in the award of a U.S. government oil concession.  Standard Oil of Indiana obtained a majority stake in 1925.  The company sold its foreign properties to Standard Oil of New Jersey in 1932.  What was left of Pan American was merged with Standard Oil of Indiana in 1954 to form Amoco.

Teapot Dome scandal: The Teapot Dome Scandal was a bribery incident that took place in the United States from 1921 to 1922, during the administration of President Warren G. Harding.  Secretary of the Interior Albert Bacon Fall had leased Navy petroleum reserves at Teapot Dome in Wyoming and two other locations in California to private oil companies at low rates without competitive bidding.  In 1922 and 1923, the leases became the subject of a sensational investigation by Senator Thomas J. Walsh.  Fall was later convicted of accepting bribes from the oil companies and became the first Cabinet member to go to prison.  No person was ever convicted of paying the bribes, however.

Nan Britton: Nanna Popham Britton (November 9, 1896 – March 21, 1991) was an American secretary who was the mistress of Warren G. Harding, the 29th President of the United States.  In 1927, she revealed that her daughter, Elizabeth, had been fathered by Harding while he was serving in the United States Senate, one year before he was elected to the presidency.  Her claim was open to question during her life, but was confirmed by DNA testing in 2015.
