Lawrence 'Larry' Joseph Ellison is an American businessman, the self-made billionaire Co-founder, Executive Chairman, and former CEO of Oracle Corporation (NYSE: ORCL), a global leader in enterprise database and cloud software. Born in New York City, in 1944, he was raised in a working-class environment by his aunt and uncle after his single mother gave him up for adoption.

Ellison dropped out of the University of Illinois in 1964 after his aunt's death and later dropped out of the University of Chicago after one semester. His career is defined by technological disruption, competitive ferocity, and a vision of cloud computing before the term existed. His structural contribution is immense: pioneering the commercial relational database.

• Oracle Corporation (Executive Chairman, CTO & Co-founder): The core publicly traded asset, a global leader in database and cloud software (with a $400+ billion market capitalization).
• Sailing and Real Estate: He is a major yachtsman (winning the America's Cup) and real estate mogul (owning 98 percent of the island of Lanai, Hawaii).
• Academic Note: He dropped out of college twice but holds an Honorary Doctorate from USC.
• Philanthropy: He is a Giving Pledge signatory and funds cancer research and education.

Larry Ellison's strategic genius was his early recognition of the relational database concept (developed by Edgar F. Codd at IBM) and his commitment to commercializing it. In 1977, he co-founded Software Development Laboratories (SDL) (later Oracle). His structural contribution is tied to pioneering the commercial database market, which is foundational to modern enterprise computing.

He served as CEO until 2014, guiding the company through immense growth and fierce competition (often with Bill Gates). His most critical recent move was the pivot to cloud computing (Oracle Cloud Infrastructure - OCI), ensuring the company's relevance in the AI era. His wealth is secured by his massive equity stake in Oracle (he is one of the richest people in the world) and his vast real estate and investment portfolio.

Larry Ellison is a Giving Pledge signatory. His structural social impact is tied to Oracle's role in providing the foundational database technology that underpins modern enterprise management globally. His personal philanthropy focuses heavily on medical research (funding the Ellison Institute for Transformative Medicine) and biodefense.

His structural contribution is tied to his belief in technology as a force for market efficiency and his commitment to environmental protection (through his conservation efforts on Lanai).

Larry Ellison maintains the casual, high-end style of a technology mogul. His attire is often professional yet relaxed, favoring bespoke blazers and unbuttoned shirts. His aesthetic reflects his immense wealth, his competitive nature (in sailing), and his maverick persona.

Residing in Lanai, Hawaii, his luxury is the immense security and autonomy derived from his multi-billion dollar fortune (one of the richest people in the world). His life is dedicated to software innovation, space colonization (investing in SpaceX), and philanthropy.
