Jean Paul Getty Sr. (; December 15, 1892 – June 6, 1976) was an American-born British petroleum industrialist who founded the Getty Oil Company in 1942 and was the patriarch of the Getty family. A native of Minneapolis, he was the son of pioneer oilman George Getty. In 1957, Fortune magazine named him the richest living American, while the 1966 Guinness Book of Records named him as the world's richest private citizen, worth an estimated $1.2 billion (approximately $7.5 billion in 2020). At his death, he was worth more than $6 billion (approximately $22 billion in 2020). A book published in 1996 ranked him as the 67th richest American who ever lived, based on his wealth as a percentage of the concurrent gross national product.Despite his vast wealth, Getty was famously frugal, notably negotiating his grandson's kidnapping ransom in 1973. He had five children and divorced five times. Getty was an avid collector of art and antiquities. His collection formed the basis of the J. Paul Getty Museum in Los Angeles; more than $661 million of his estate was left to the museum after his death. He established the J. Paul Getty Trust in 1953. The trust, which is the world's wealthiest art institution, operates the J. Paul Getty Museum Complexes: the Getty Center, the Getty Villa and the Getty Foundation, the Getty Research Institute, as well as the Getty Conservation Institute.
