Jerral Wayne Jones (born October 13, 1942) is an American billionaire businessman who has been the owner, president, and general manager of the Dallas Cowboys of the National Football League (NFL) since 1989. According to an interview with Jones on HBO, after graduating from college in 1965, he borrowed a million dollars from Jimmy Hoffa's Teamsters union to open up a string of Shakey's Pizza Parlor restaurants in Missouri.[citation needed] When that venture failed, Jones was given a job at his father's insurance company, Modern Security Life of Springfield, Missouri. He received his master's degree in business in 1970. After several other unsuccessful business ventures (including an attempt, again using Teamsters money, to purchase the American Football League's San Diego Chargers in 1967), he began an oil and gas exploration business in Arkansas, Jones Oil and Land Lease, which became successful. His privately held company currently does natural resource prospecting. (Source: Wikipedia.org, CC BY-SA)
