Harold Hamm, a name that’s synonymous with the oil and gas industry, began his career in the most unlikely of places – a gas station in Oklahoma. Born into a humble family, Hamm’s first job was pumping gas and cleaning restrooms, a far cry from the boardrooms he would later command. It was here that he first developed his keen eye for detail and understanding of the industry, traits that would serve him well in the years to come.

In the late 1960s, Hamm took a leap of faith and started his own company, Continental Resources. With a small team and a big dream, he began exploring for oil in the then largely untapped Bakken Shale formation in North Dakota. His gamble paid off when he discovered a massive oil reserve, transforming Continental into one of the most successful independent oil and gas exploration and production companies in the United States. This discovery not only made Hamm a household name in the industry but also catapulted him to the ranks of the wealthiest people in the world.
