Who Is Adda Quinn?
Adda Quinn is an American business professional who gained public attention through her marriage to Larry Ellison, the co-founder of Oracle Corporation. Although many people recognize her because of her former husband, Quinn built an accomplished career of her own in environmental research administration. Unlike many individuals connected to high-profile business leaders, she has consistently chosen to stay out of the spotlight. She has chosen to live a private life, seldom appearing in interviews or maintaining a notable presence on public social media platforms. Instead of seeking the spotlight, she has devoted most of her time and energy to her career and personal pursuits. Her decision to maintain a private lifestyle has only increased public curiosity over the years, especially as Larry Ellison became one of the most influential figures in the technology industry.
Early Life and Background
Little verified information is publicly available about Adda Quinn’s early life. Details about her childhood, parents, birth date, and education have never been disclosed, as she has chosen to keep her personal life private. By the mid-1960s, Quinn was living in the San Francisco Bay Area, which was rapidly becoming a center for business, science, and technological innovation. During this time, she met Larry Ellison, and the two soon began their relationship. Details about her education have not been publicly confirmed. However, her later career at the Electric Power Research Institute (EPRI) reflects extensive experience in management and overseeing large research programs.
How Adda Quinn Met Larry Ellison
Adda Quinn met Larry Ellison in 1967 through a Berkeley employment agency in California. At the time, Ellison was still searching for career direction. He had left college without completing a degree and worked various programming jobs while trying to establish himself in the growing computer industry. Their relationship developed quickly. Quinn admired Ellison’s confidence, intelligence, and ambitious mindset, while Ellison appreciated her stability and practical outlook on life. Within a short period, the couple decided to marry and begin building a future together. Neither could have imagined that Ellison would later become one of the world’s most successful technology entrepreneurs.
Marriage to Larry Ellison
Adda Quinn and Larry Ellison married in 1967, years before Oracle Corporation existed. During the early years of their marriage, money was limited. The couple reportedly lived in a small one-room apartment for nearly three years before purchasing a modest home in Oakland, California. Ellison worked a series of programming and technology-related jobs while learning about database systems, experiences that later helped shape Oracle’s future success. Quinn supported the household during this challenging period, managing everyday responsibilities while encouraging her husband to pursue his ambitions. Although life was financially difficult, these years played an important role in Ellison’s personal and professional development.
Adda Quinn and Larry Ellison: The End of Their Marriage
As the years passed, differences between the couple became more noticeable. Financial pressures, uncertain career prospects, and contrasting priorities gradually placed strain on their relationship. While Ellison remained focused on taking risks and pursuing bigger opportunities, Quinn preferred financial stability and long-term security. The couple reportedly attended marriage counseling in an effort to save their relationship. Despite those efforts, they ultimately decided to separate. Their divorce was finalized in 1974, ending a seven-year marriage that took place long before Larry Ellison founded Oracle and became a billionaire. Although their relationship ended, Quinn moved forward with her own life and career instead of remaining defined by her former marriage.
Adda Quinn’s Career at EPRI
After her divorce from Larry Ellison, Adda Quinn focused on building a successful professional career instead of seeking public attention. She joined the Electric Power Research Institute (EPRI) in Palo Alto, California, where she worked in business and environmental program management. At EPRI, Quinn held important leadership responsibilities. She managed a team of more than 40 researchers and oversaw multimillion-dollar research budgets dedicated to environmental projects. Her work involved coordinating scientific studies, managing financial planning, and supporting programs related to land and water quality. Over time, her strong organizational skills and leadership earned her greater responsibilities within the organization. Rather than becoming known as the former wife of a future billionaire, Quinn established herself as a respected professional in her own field. Her career at EPRI reflects years of dedication, hard work, and expertise in managing large-scale research programs.
Life After Divorce
Larry Ellison, whose name became closely associated with Silicon Valley and the technology industry, Adda Quinn chose a much quieter path after their marriage ended. She remained focused on her career, avoided media attention, and rarely spoke publicly about her relationship with Ellison. While public curiosity about her life continued to grow as Oracle expanded into one of the world’s largest software companies, Quinn preferred privacy over publicity. Friends and colleagues have described her as someone who valued professionalism, independence, and personal fulfillment rather than fame. Her decision to stay out of the spotlight has made verified information about her later life relatively limited.
Second Marriage to George Sublett
Several years after her divorce, Adda Quinn found happiness again. In 1990, she married George Sublett, an engineer who shared many of her interests. Through this marriage, Quinn became a stepmother to George’s two sons and later enjoyed spending time with their growing family. The couple shared a love for travel and outdoor activities. They explored different parts of the world together and enjoyed hobbies such as horseback riding, hiking, sailing, and nature trips. Their marriage reflected a peaceful lifestyle built on companionship rather than public recognition. Compared with her first marriage, Quinn’s second marriage remained almost entirely private.

After George Sublett’s passing, Adda Quinn remained committed to her private lifestyle and chose to keep her grief out of the public eye.

Her ability to move forward with dignity while maintaining her privacy reflects the same quiet strength that has characterized much of her life.
