Tony Petrello has made headlines several times as one of the highest-paid CEOs in America with a total compensation of over $27 million. He’s the CEO of Nabors Industries, a large oil drilling contractor based in Houston, TX with holdings all across the world. He guides the companies technology and marketing strategies and also helps maintain positive relations with investors.

But prior to becoming an oil industry magnate Petrello was a protégé of Mathematics professor Serge Lang, an account that his roommate Lloyd Grove shares with The Daily Beast.

Anthony Petrello grew up in New Jersey and always enjoyed studying mathematics in his spare time. He earned a scholarship to Yale University where he was Grove’s roommate and majored in Advanced Mathematics. He graduated with high honors from Yale, but instead of becoming a mathematician or professor he went into corporate law, completing his J.D. at Harvard University. He practiced law for 13 years at Baker & McKenzie specializing in foreign transactions and tax compliance. He joined Nabors Industries as Chief Operating Officer in 1991.

Petrello’s greatest love is his daughter Carena, a young girl that has struggled with cerebral palsy. It was very difficult for Tony and his wife Cynthia Petrello to hear that there was no cure for cerebral palsy, but they haven’t given up on the idea that one day a cure might be found. They’ve contributed to neurological research at the Dan and Jan Duncan Neurological Research Institute at the Texas Children’s Hospital and have been spreading word about charity towards neurology to other businessmen.
