Larry Ellison

Ashkenazi Jewish

Raised by an adoptive father he has described as a Russian immigrant.

Jewish (Reform)

A stable, middle-class adoptive home existed, but Ellison has described his relationship with his adoptive father as distant and unsupportive. Whether it functioned as a usable fallback by the time he founded Oracle in 1977 is not established.

A re-employable skill, not a person. He worked salaried programming jobs at Amdahl, Ampex, and Omex through the early-to-mid 1970s in a Silicon Valley computer industry with strong demand for that skill.

Adoptive father Louis Ellison was a government employee who had made and then lost a real-estate fortune in Chicago during the Depression; one other account describes him as an accountant. Adoptive mother Lillian Spellman Ellison is described as warm and loving; her occupation isn't established.

His birth mother, Florence Spellman, was 19 and unmarried and "really was unable to care for" him, in his words. She tried until he was nine months old, then he was adopted by her aunt and uncle, Lillian and Louis Ellison, in Chicago. He didn't know he was adopted until he was twelve.

Not established as sanction. Ellison describes his adoptive father as authoritarian and unsupportive of questioning authority, which reads as the opposite of the kind of active permission this field is meant to capture.

Transferred from birth mother to adoptive aunt and uncle at nine months old, following a bout of pneumonia.

Chicago's South Shore, a majority-white neighborhood with a Jewish population estimated around 20 percent in the early 1950s. One biographer, pushing back on a poorer version of the story, has written that the family "was not poor" and the neighborhood "was once one of the south side's most desirable."

Born in the Bronx; moved to Chicago at nine months via adoption; moved to California (Berkeley) in 1966 after leaving college, which is where his technology career and Oracle both began.

Moved as an infant to live with, and be raised by, his mother's aunt and uncle in Chicago rather than a random adoptive placement.

Ampex Corporation, where accounts describe him working on a database project for the CIA nicknamed "Oracle," alongside Bob Miner, who supervised him and later co-founded the company with him.

Bob Miner and Ed Oates, both met through prior Silicon Valley jobs; Bruce Scott joined shortly after as a third technical co-founder. Miner had been Ellison's supervisor at Ampex.

Professional-grade access to IBM-compatible mainframe development at Amdahl and advanced database engineering at Ampex, at a time when that equipment and training were not broadly available outside a handful of firms.

No degree. Attended the University of Illinois Urbana-Champaign (1962–1964, pre-med, left after his adoptive mother's death) and the University of Chicago (one term in 1966, physics and math) without completing either.

About $2,000 pooled among the three founders to start Software Development Laboratories in June 1977; $1,200 of it was Ellison's own savings, for 60% ownership. Miner and Oates put in $400 each for 20% apiece.

It paid its own way from the start. Revenue came before any outside money.

Grew on revenue through the mid-1980s with no confirmed institutional venture round before its March 1986 IPO, though venture capitalist Donald L. Lucas joined the board as chairman in 1980. After the 1990 near-collapse, the company took a $250 million bank credit line, a further $100 million financing in October 1991, and an $80 million investment from Nippon Steel in December 1991. Ellison has held roughly a quarter to 40% of Oracle for decades.

Built on Edgar F. Codd's academic paper describing the relational database model. Ellison tracked IBM's own published research and moved to ship a commercial relational database before IBM did; IBM refused to share System R's error codes when he sought compatibility.

Oracle's 1990 near-collapse was absorbed by the company itself, through a bank credit line and later outside financing, restated earnings, and layoffs — not by Ellison personally.

Codd's relational model was published in academic form but not yet commercialized; IBM was still developing its own relational products. Oracle shipped a commercial relational database roughly two years ahead of IBM's SQL/DS.

Built. Created the first commercial relational database product rather than acquiring an existing one.

Nearly all of it is Oracle stock, an appreciating owned asset, not salary or other income.

Two America's Cup wins with Oracle Team USA (2010 and 2013); acquired roughly 98% of the Hawaiian island of Lānaʻi in 2012.

Uncapped

A Delaware Chancery Court ruled in 2003 that Ellison and then-CFO Jeffrey Henley were not liable for insider trading over his January 2001 sale of nearly $900 million in Oracle stock, made shortly before a March 2001 earnings warning that cut the stock's value roughly in half. A related shareholder derivative suit was separately settled in September 2005, when Ellison agreed to donate $100 million of his own money over five years to charity in Oracle's name, without admitting wrongdoing; a judge separately blocked Oracle from reimbursing about $24 million of his legal fees.

In 2000, during Oracle's public campaign against Microsoft, the company hired investigators who examined the trash of Microsoft-aligned advocacy groups, reportedly including a $1,200 offer to janitors at one group's office. Ellison publicly defended it, calling it "unsavory, yucky — kind of. But legal," and framed it as a public service exposing how Microsoft was shaping opinion through front groups.
