John Paul Getty III was the grandson of American oil tycoon J. Paul Getty, who was once the richest man in the world. While living in Rome in 1973, he was kidnapped by the 'Ndrangheta and held for a $17 million ransom. His grandfather was reluctant to pay, but, after John Paul Getty III's severed ear was received by a newspaper, the grandfather negotiated a payment of $2.2 million, and Getty was released five months after being kidnapped. Getty subsequently developed an addiction to drugs and alcohol, leading to an overdose and stroke which left him severely disabled for the rest of his life.

Jean Paul Getty Sr. 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 wealthiest living American, while the 1966 Guinness Book of Records declared him the world's wealthiest private citizen, worth an estimated $1.2 billion. At the time of his death, he was worth more than $6 billion. A book published in 1996 ranked him as the 67th wealthiest American who ever lived.
