Ortega first began his career manufacturing textiles through a small family company in 1963. He owns a 10% stake in Spanish telecoms firm Telxius and 5% of publicly traded natural gas grid operator Enag's.

Ellison never finished college. He started out building databases for the CIA. Daughter Megan has financed films such as Zero Dark Thirty and American Hustle; son David produced mainstream movies like The Terminator and Mission: Impossible".
