The life and career of Larry Ellison, Oracle CEO and founder, who went from college drop-out to the world's fifth richest person

When he was 9 months old, Larry came down with pneumonia, according to Vanity Fair. His mom sent him to Chicago to live with his aunt and uncle, Lillian and Louis Ellison.

Vanity Fair reported that Louis, his adoptive father, was a Russian immigrant who took the name "Ellison" in tribute to the place in which he entered the US: Ellis Island.

Ellison went to high school in Chicago's South Side before attending the University of Illinois at Urbana-Champaign. When his adoptive mother died during his second year at college, Ellison dropped out. He tried college again later at the University of Chicago but dropped out again after only one semester, Vanity Fair reported.

He made the trip from Chicago to California in a flashy turquoise Thunderbird that he thought would make an impression in his new life, according to Vanity Fair.

Ellison bounced around from job to job, including stints at companies like Wells Fargo and the mainframe manufacturer Amdahl. Along the way, he learned computer and programming skills.

The company started with $2,000 of funding.

Ellison and company were inspired by IBM computer scientist Edgar F. Codd's theories for a so-called relational database — a way for computer systems to store and access information, according to Britannica. Nowadays, they're taken for granted, but in the '70s, they were a revolutionary idea.

In 1979, the company renamed itself Relational Software Inc., and in 1982, it formally became Oracle Systems Corp., after its flagship product.

As one of the key drivers of the growing computer industry, Oracle grew fast. The company is responsible for providing the databases in which businesses track information that is crucial to their operations.

Ellison became a billionaire at age 49. Now, he has a net worth of roughly $146 billion, according to Forbes, after racking up $50 billion in gains thanks to Oracle and Tesla stock. That makes him the seventh-richest person in the world.

Oracle reported a loss of $36 million in September 1990 after admitting that it had miscalculated its revenue earlier that year, according to The New York Times.

It didn't get the decade off to a great start. After adjusting for that error, Oracle was said to be close to bankruptcy. At the same time, rivals like Sybase were eating away at Oracle's market share.

It took a few years, but by 1992, Ellison and Oracle managed to right the course with new employees and the popular Oracle7 database.

For much of the '90s, he and Oracle were locked in a public-relations battle with the competitor Informix, which went so far as to place a "Dinosaur Crossing" billboard outside Oracle's Silicon Valley offices at one point, Fortune reported in 1997.

With Ellison as Oracle's major shareholder, his millions kept rolling in. He started to indulge in some expensive hobbies — including yacht racing. That's Ellison at the helm during a 1995 race.

He also partly financed the BMW Oracle USA sailing team, which won the America's Cup in 2010, according to Bloomberg.

In 1999, Ellison's protégé, Marc Benioff, left Oracle to work on a new startup called Salesforce.com. Ellison was an early investor, putting $2 million into his friend's new venture.

When Benioff found out that Ellison had Oracle working on a direct competitor to Salesforce's product, he tried to force his mentor to quit Salesforce's board. Instead, Ellison forced Benioff to fire him — meaning Ellison kept his shares in Salesforce.

Given that Salesforce is now a $267 billion company, Ellison personally profits even when his competitors do well. It has led to a love-hate relationship between the two executives that continues to this day, with the two taking shots at each other in the press.

All of those new dot-com companies needed databases, and Oracle was there to sell them. Although investors lost out in the dot-com crash, Oracle came out of it stronger due to its acquisitions and the demand for software solutions.

In 2005, for example, Oracle snapped up the HR software provider PeopleSoft for $10.3 billion.

And in 2010, Oracle completed its acquisition of Sun Microsystems, a server company that started at about the same time as Oracle, in 1982. That acquisition gave Oracle lots of key technology, including control over the popular MySQL database.

Ellison has expensive taste. Over the years he's built up an impressive collection of Richard Mille watches, an expert previously told BI. The timepieces start in the six-figure range and can go for over $1 million in some cases.

In 2009, the billionaire purchased the Indian Wells tennis tournament for a reported $100 million, according to The Los Angeles Times.

By signing the pledge, Ellison promised to donate 95% of his fortune before he dies. And in May 2016, Ellison donated $200 million to a cancer treatment center at the University of Southern California, Forbes reported.

Ellison hired Hurd, a former CEO of HP, in 2010, Inc reported. Catz has made a reputation for herself among analysts for what they describe as brilliant business strategy.

Ellison founded a startup called Sensei in 2016 that does hydroponic farming and owns a wellness retreat on Lanai.

He also purchased Hawaiian budget airline Island Air in 2014, before selling a controlling interest in the airline two years later after it struggled financially.

Ellison handed control over to Hurd and Catz, who became co-CEOs. Ellison now serves as the company's chairman and chief technology officer. Following Hurd's death in 2019, Catz became the sole CEO.

Back in 1998, Ellison had made a $125 million investment in ex-Oracle exec Evan Goldberg's startup business-management software firm, NetSuite. It ended up working out well for Ellison when NetSuite CEO Zach Nelson negotiated the sale of the company to Oracle for $9.3 billion, netting Ellison a cool $3.5 billion in cash for his stake.

NetSuite investor T. Rowe Price tried to block the deal, citing Ellison's conflict of interest, but the sale closed in November 2016.

Ellison has held shares in some of the most recognizable companies, one of which was the infamous blood-testing company Theranos, founded by Elizabeth Holmes. It had a promising future until its flaws were exposed and Holmes received a prison sentence.

When Steve Jobs returned to Apple as CEO back in 1997, he asked Ellison to sit on the board. Ellison served for a while, but felt that he couldn't devote the time and left in 2002, according to Forbes. Compensation for his role was an option to buy about 70,000 shares, which would've amounted to about $1 million at the time of his departure.

Ellison reportedly owns the Astor Beechwood Mansion in Newport, Rhode Island, and a home in Malibu. Ellison also has houses in Palm Beach, Florida and more in a multibillion-dollar real estate portfolio.

His daughter, Megan, is an Oscar-nominated film producer and the founder of Annapurna Pictures. The company has produced films like "Zero Dark Thirty" and "American Hustle."

Ellison's son, David, is also in the film business. His company, Skydance Media, has produced movies like "Terminator: Dark Fate" and films in the "Mission: Impossible" franchise. Whispers of David becoming the new owner of Paramount swirled in April due to his father's net worth.

Ellison has been married and divorced four times. He has most recently dated Nikita Kahn, a model and actress.

Ellison said publicly that he supported Trump and wants him to do well, and hosted a Trump fundraiser at his Rancho Mirage home in February, though he did not attend. The fundraiser caused an outcry among Oracle employees, who started a petition asking senior Oracle leadership to stand up to Ellison.

Catz, the CEO of Oracle, also had close ties to the Trump administration, having served on Trump's transition team. 

Ellison and Trump remained close during Trump's time in office and reportedly spoke on the phone about possible coronavirus treatments. Trump also supported Oracle's bid to buy TikTok, calling Oracle a "great company."  

Earlier in 2018, Ellison described Tesla CEO Elon Musk as a "close friend," and defended him from critics. When Musk acquired Twitter — now X — in 2022, Ellison offered to invest $1 billion.

Musk went on to help Ellison reset his forgotten password, according to biographer Walter Isaacson.

The announcement came after Oracle decided to move its headquarters to Austin, Texas, leading Oracle employees to ask Ellison if he planned to move to Texas too.

"The answer is no," Ellison wrote in a company-wide email. "I've moved to the state of Hawaii and I'll be using the power of Zoom to work from the island of Lanai."

He signed the email: "Mahalo, Larry."

In a proxy filing in June 2022, the electric vehicle maker revealed that Ellison would be leaving the board. Since then, he and Musk have appeared to maintain their close relationship.

Oracle's shares continued to hit records, CNBC reported. The company proved that it's not going any where any time soon.

Oracle joined other tech giants, like Salesforce, in backing the tech startup in June 2023. It began offering generative AI to its clients based on tech made by Cohere.

"Cohere and Oracle are working together to make it very, very easy for enterprise customers to train their own specialized large language models while protecting the privacy of their training data," Ellison previously said.

Despite its big move to Austin only four years ago, Ellison said that Oracle is planning to move its world headquarters to Nashville, Tennessee.

In April 2024, the exec announced that Oracle has plans for a "huge campus" in Nashville that will one day serve as the software giant's world headquarters. The company relocated from the San Francisco area to Austin, Texas in 2020.

"It's the center of the industry we're most concerned about, which is the healthcare industry," Ellison said at the Oracle Health Summit in Nashville, according to CNBC.
