Adda Quinn is best known as the first wife of billionaire entrepreneur Larry Ellison, the co-founder of Oracle Corporation. Although Ellison became one of the world’s most influential technology leaders, Adda Quinn has lived a remarkably private life. Unlike many people associated with high-profile public figures, she has largely avoided media attention and has never sought celebrity status. Adda Quinn has grown in recent years as people search for information about Larry Ellison’s early life, his first marriage, and the people who supported him before Oracle became one of the world’s largest software companies. Despite this curiosity, verified information about Adda Quinn remains limited because she has consistently chosen to keep her personal life out of the public eye. This article explores everything publicly known about Adda Quinn, including her biography, marriage, career, personal life, and why she continues to attract public interest.
Who Is Adda Quinn?
Adda Quinn is an American woman who gained public recognition because of her marriage to Larry Ellison. Their relationship began long before Ellison achieved worldwide fame and financial success through Oracle Corporation.
Unlike many spouses of famous entrepreneurs, Adda Quinn never became a public personality. Even after her marriage ended, she continued to maintain a low profile, making only limited information about her available through public sources.
Today, she is remembered primarily as an important figure in Larry Ellison’s early life rather than as a public celebrity in her own right.

Early Life and Background
One reason Adda Quinn continues to intrigue readers is the lack of publicly available information about her early years.
Unlike many individuals connected to famous personalities, there are no verified public records detailing her:
- Birth date
- Birthplace
- Parents
- Siblings
- Childhood
- Educational background
This lack of information is not unusual for someone who has intentionally avoided public attention. Most biographies discussing Adda Quinn acknowledge that little is known about her life before she met Larry Ellison.
As a result, any claims regarding her early life that are unsupported by credible sources should be treated with caution.
Marriage to Larry Ellison

The most well-known chapter of Adda Quinn’s life is her marriage to Larry Ellison.
According to published accounts, the couple met in 1967, reportedly through a Berkeley employment agency during the early stages of Ellison’s professional career. They married later that year.
At the time, Larry Ellison was far from becoming the billionaire entrepreneur people know today. He was still building his career in computer programming and working a variety of technical jobs.
The couple reportedly lived modestly while Ellison searched for better career opportunities in California’s growing technology industry.
Their marriage lasted approximately seven years before ending in divorce in 1974.
This timeline is significant because Oracle Corporation was founded in 1977, several years after their divorce. Consequently, Adda Quinn was not involved in the development or success of Oracle.
Life Before Oracle’s Success
One fascinating aspect of Adda Quinn’s story is that she knew Larry Ellison before he became one of the world’s wealthiest people.
During their marriage:
- Ellison was still developing his programming skills.
- He worked various technical positions.
- Financial resources were relatively limited.
- Oracle did not yet exist.
Many biographies highlight this period because it represents a very different stage of Larry Ellison’s life—long before private jets, luxury yachts, and global business influence became part of his story.
Although Adda Quinn witnessed Ellison’s ambition and early career development, their relationship ended before his breakthrough success.
Career and Professional Life
While Adda Quinn is frequently identified because of her former marriage, reports indicate that she built her own professional career.
Several biographies state that she worked for the Electric Power Research Institute (EPRI) in Palo Alto, California.
Her reported responsibilities included:
- Business management
- Project management
- Coordinating research initiatives
- Managing environmental research programs
- Supervising project budgets
- Working with multidisciplinary research teams
Although publicly available employment records remain limited, multiple secondary sources consistently describe her as a capable business professional rather than someone defined solely by her relationship with Larry Ellison.
This independent career reflects her commitment to maintaining a professional identity outside the spotlight.
Life After Divorce
Following her divorce from Larry Ellison, Adda Quinn largely disappeared from public attention.
Unlike many former spouses of high-profile individuals, she did not write memoirs, participate in interviews, or capitalize on her connection to a future billionaire.
Instead, reports suggest she focused on:
- Building her career
- Maintaining personal privacy
- Living independently
- Pursuing her own interests
This decision has contributed to the mystery surrounding her life and explains why verified information remains relatively scarce.
Reported Second Marriage
According to several published biographies, Adda Quinn later married George Sublett around 1990.
Reports indicate that:
- George Sublett had two sons from a previous relationship.
- Adda Quinn became their stepmother.
- The family maintained a private lifestyle.
Some sources also report that George Sublett passed away in 2010 following long-term health complications after a horseback riding accident.
As with many aspects of Adda Quinn’s personal life, detailed public documentation remains limited.
Personal Interests
Although Adda Quinn has never publicly discussed her hobbies, several biographies attribute several interests to her.
Reported activities include:
- Horseback riding
- Gardening
- Traveling
- Backpacking
- Sailing
- Skiing
- Cooking
- Reading
These interests suggest someone who values outdoor recreation, lifelong learning, and a balanced lifestyle rather than public recognition.
