Jean Paul Getty Sr. (December 15, 1892 – June 6, 1976) was an American petroleum industrialist who founded the Getty Oil Company in 1942 and was the patriarch of the Getty family. A native of Minneapolis, Minnesota, he was the son of pioneer oilman George Getty. In 1957, Fortune magazine named J. Paul Getty the wealthiest living American, while the 1966 Guinness Book of Records declared him to be the world's wealthiest private citizen, worth an estimated $1.2 billion (approximately $8.8 billion in 2024). At the time of his death, he was worth more than $6 billion (approximately $26 billion in 2024). A book published in 1996 ranked him as the 67th wealthiest American who ever lived (based on his wealth as a percentage of the concurrent gross national product).
Getty was known for his frugality, going so far as to haggle with the kidnappers when his grandson was held to 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.
