D iane Kemper is an American heiress to the fortune of her late father, Anderson B. (Andy) Anderson. Her father was a self-made Texas oilman who founded the Anderson Exploration Company. He was a pioneer in the energy industry, successfully drilling for oil and gas and building a substantial energy enterprise.

Upon her father's death, his fortune, including the assets of his exploration company and other investments, was passed on to his heirs, including Diane. Her wealth is derived from this substantial inheritance. Like many families whose wealth is based on private oil and gas holdings, the Kemper family maintains a very low public profile.
