E leanor Butt Crook is an American heiress to the H-E-B supermarket fortune. She is the daughter of Howard Butt Sr., who expanded the company, and the sister of Charles Butt, the longtime chairman and CEO who transformed the family business into a retail giant. The company was founded by her grandmother, Florence Butt, as a small grocery store in Kerrville, Texas, in 1905.

While her brother Charles has been the driving force behind the company's massive growth and success, Eleanor and her other siblings inherited a significant stake in the privately held company. Her wealth is derived from her ownership of this highly profitable and beloved Texas-based supermarket chain. She is known for her extensive philanthropic work, particularly in the areas of global hunger and malnutrition, through the Eleanor Crook Foundation.
