| Larry Ellison |
Net Worth: $39.5 (up from $28.0 billion)
Larry Ellison is the co-founder and chief executive officer of Oracle Corporation, one of the world's leading enterprise software companies. As of 2011, he is the third wealthiest American citizen, with an estimated worth of $33 billion.
Larry Ellison was born in the Bronx, New York City to Florence Spellman, an unwed 19-year-old. Ellison graduated from Eugene Field Elementary School on Chicago's north side in January, 1958 and attended Sullivan High School at least through the fall of 1959 before moving to South Shore. Ellison was a bright but inattentive student. He left the University of Illinois at Urbana-Champaign at the end of his second year, after not taking his final exams because his adoptive mother had just died. After spending a summer in Northern California, where he lived with his friend Chuck Weiss, Ellison attended the University of Chicago for one term, where he first encountered computer design. In 1964, at 20 years of age, he moved to Northern California permanently.
During the 1970s, after a brief stint at Amdahl Corporation, Ellison worked for Ampex Corporation. One of his projects was a database for the CIA, which he named "Oracle".
Ellison was inspired by the paper written by Edgar F. Codd on relational database systems called "A Relational Model of Data for Large Shared Data Banks". In 1977, he founded Software Development Laboratories (SDL). In 1979, the company was renamed Relational Software Inc., later renamedOracle after the flagship product Oracle database. He had heard about the IBM System R database, also based on Codd's theories, and wanted Oracle to be compatible with it, but IBM made this impossible by refusing to share System R's code. The initial release of Oracle was Oracle 2; there was no Oracle 1. The release number was intended to imply that all of the bugs had been worked out of an earlier version.
