Known as the “prince of petroleum,” Cosden is credited with establishing Oklahoma as a major oil producing state. Starting with a small parcel of land, he built a $35 million oil business in ten short years. Through his oil discoveries and exploration, he almost single-handedly quadrupled the population of Tulsa at the turn of the century.
