Coming in at the third spot, Ellison is estimated to have slightly over $53 billion. He is 70 years old and resides in Woodside, California. Oracle is the source of his financial success. His humble beginnings include being born in the Bronx to a single mother who eventually sent him to Chicago to be raised by his aunt and uncle. Ellison learned the basics of computer programming at a young age but dropped out of college and spent several years bouncing from job to job in California. After becoming a computer programmer at Amdahl Corporation, he was part of building the first mainframe system that was IBM-compatible. In 1977, along with a few other Amdahl colleagues, he started his own business. Ellison and his team eventually created Oracle, a relational database management system. Although originally used for the CIA, IBM eventually used Oracle for its own mainframe systems. Oracle’s sales continued to grow, and eventually it became a billion-dollar company. In the last few months, Ellison has announced that he plans to step down as head of Oracle, but he plans to stay involved with the company. He will be particularly involved with Oracle’s technology development.
