Summa Corporation Summa Corporation was the name adopted for the business interests of Howard Hughes after he sold the tool division of Hughes Tool Company in 1972. The tool division would merge with Baker International in 1987 to form Baker Hughes, the world's third-largest oil-services company. The name "Summa", Latin for "highest", was allegedly chosen by several of Hughes' employees without consulting him first. Hughes was allegedly dissatisfied, and preferred the name "HRH Properties" - with the initials standing for both "Howard Robard Hughes" and "Hughes Resort Hotels". His suggestions were never implemented, and the company remained Summa for 18 years following Hughes' death.
