Adda Quinn: the woman who left Larry Ellison before the money
Adda Quinn was Larry Ellison’s first wife. They met at a Berkeley employment agency in 1967, married within months, and divorced in 1974. Three years later he co-founded the company that became Oracle.
She went on to spend about a decade running a research division at the Electric Power Research Institute in Palo Alto, managing a budget near $45 million and roughly 45 doctoral researchers. That career is barely mentioned on most pages carrying her name, which is a strange omission given it lasted longer than the marriage.

How they met
Ellison was in his early twenties, a college dropout picking up scattered programming work. He walked into an employment agency in Berkeley looking for a job. Quinn worked there.
They married within months of meeting. She later described him to a reporter as “the most fascinating man I’d ever met in my life”, adding that she knew she would never be bored with him.
Mike Wilson, who wrote the standard biography of Ellison, places them both at around 23 when they met.
Seven years, and no money
The marriage ran from 1967 to 1974, which was the least promising stretch of Ellison’s working life.
He moved between contract jobs and never earned much. What he did do was spend like a man who already had money. Accounts of the period describe a monthly budget of roughly $1,600 alongside a sailboat that cost about $3,000. Sailing later became the thing he was famous for spending on. It started here, when he could not afford it.
Quinn was the one absorbing the consequences.
The counselling session
The couple went to marriage counselling before the end, and one exchange from those sessions has become part of Silicon Valley folklore.
Ellison, by several accounts, promised that if she stayed he would become a millionaire and buy her whatever she wanted. Quinn’s answer was that he should go and make his millions for his own sake, because she was leaving either way.
She did leave. The divorce was finalised in 1974. There were no children.
It is worth being clear about what that timing meant. Oracle’s predecessor company was founded in 1977. Ellison had no fortune in 1974, and there was no settlement tied to wealth that did not yet exist. Anyone framing this as a woman who missed out on a payday has the sequence backwards. She left a man with a sailboat he could not afford.
What Ellison did years later
This is the part of the story no competing page carries, and it comes from a newspaper archive rather than an aggregator.
The two stayed friends after the divorce. Years later, when Quinn’s parents became ill, Ellison bought them a house so that she would not have to worry about the money.
That single fact does more to explain the marriage than any amount of speculation about why it ended. Whatever went wrong between them in the early seventies, he did not forget her, and she let him help.
Her career at the Electric Power Research Institute
After the divorce Quinn built a professional life of her own in Palo Alto.
EPRI is a research organisation working on electricity generation, transmission and environmental impact. Quinn worked as Business Manager in its Environmental Division for around a decade. The role, as consistently described across sources, involved:
- An annual budget of roughly $45 million
- A team of about 45 doctoral researchers
- Oversight of the Land and Water Quality Program
- Work on manufactured gas plant site remediation and PCB containment
Those are real and specific responsibilities. Running a $45 million research programme is a serious job by any measure, and it is the actual answer to what Adda Quinn did with her life.
She later married George Sublett and became stepmother to his two sons. She has lived privately in Northern California since, and has given no interviews beyond the brief recollections that appear in coverage of Ellison.
The X account that probably isn’t her
An account on X using the handle AddaQuinn74 describes itself as belonging to the first wife of the Oracle founder.
The same bio claims she is a top shareholder in Tesla and describes involvement with SpaceX Falcon 9 launches, the Dragon capsule and the Crew-7 mission. None of that is supported anywhere, and the phrasing does not read like a genuine account.
Treat it as unverified. A woman who has avoided publicity for fifty years is an unlikely candidate for a social media presence built on billionaire name-dropping.
What isn’t verified
- Her birth date and age. Not publicly disclosed anywhere. Wilson’s biography places her at about 23 in 1967, which would suggest a birth year around 1944, but that is an inference rather than a record.
- The year of her second marriage. Sources give 1990. One says the marriage lasted until George Sublett’s death in 2010. Neither is documented against a primary record.
- Whether she has biological children. Most accounts say none, and describe her as a stepmother and grandmother. At least one reference site says she had children of her own after the divorce. The stepmother version has more support.
- The exact EPRI dates and job title. The figures repeat consistently across pages, which suggests a single underlying source rather than independent confirmation.
- A net worth. No figure exists. Whatever she has, she earned at EPRI.
- Her residence. “Northern California” is as specific as anyone should get about a private person.

Conclusion
The version of this story that gets told is about a woman who walked away from a billionaire before he was a billionaire. That framing makes her a footnote in his life.
The better version is that she left a man who could not manage money and told him to go and earn it for himself. Then she spent a decade running a research programme with a $45 million budget. He kept the sailboat. She got the career.
