|children = David Ellison Megan Ellison |website = }} Lawrence Joseph "Larry" Ellison (born August 17, 1944) is an American internet entrepreneur, businessman and philanthropist. He serves as executive chairman and chief technology officer of Oracle Corporation, having previously been chief executive from its founding until September 2014. In 2014, he was listed by ''Forbes'' as the third-wealthiest man in America and as the fifth-wealthiest person in the world, with a fortune of $56.2 billion.〔 Ellison was born in New York City but grew up in Chicago. He studied at the University of Illinois at Urbana–Champaign and the University of Chicago without graduating before moving to California in 1966. While working at Ampex in the early 1970s, he became influenced by Edgar F. Codd's research on relational database design, which led in 1977 to the formation of what became Oracle. Oracle became a successful database vendor to mid- and low-range systems, competing with Sybase and Microsoft SQL Server, which led to Ellison being listed by Forbes as the richest Californian in 2006. Ellison has donated up to 1% of his wealth to charity and has signed The Giving Pledge. In addition to his work at Oracle, Ellison has had success in yachting, through Oracle Team USA, and is a licensed aircraft pilot who owns two military jets. ==Early life and education== Larry Ellison was born in New York City, to an unwed Jewish mother. His father was an Italian American United States Army Air Corps pilot. After Ellison contracted pneumonia at the age of nine months, his mother gave him to her aunt and uncle for adoption.〔 He did not meet his biological mother again until he was 48. Ellison moved to Chicago's South Shore, a middle-class Jewish neighborhood. He remembers his adoptive mother as warm and loving, in contrast to his austere, unsupportive, and often distant adoptive father, who adopted the name Ellison to honor his point of entry into the United States, Ellis Island. Louis Ellison was a government employee who had made a small fortune in Chicago real estate, only to lose it during the Great Depression.〔 Although Ellison was raised in a Reform Jewish home by his adoptive parents, who attended synagogue regularly, he remained a religious skeptic. Ellison states: "While I think I am religious in one sense, the particular dogmas of Judaism are not dogmas I subscribe to. I don't believe that they are real. They're interesting stories. They're interesting mythology, and I certainly respect people who believe these are literally true, but I don't. I see no evidence for this stuff." At age thirteen, Ellison refused to have a bar mitzvah celebration.〔Symonds and Ellison, (pp. 19-20 ).〕 Ellison says that his love affair with Israel is not connected to religious sentiments, but rather due to the innovative spirit of Israelis in the technology sector.〔Matthew Symonds, Larry Ellison. ''Software: An Intimate Portrait of Larry Ellison and Oracle'' Simon and Schuster, 2004. pp389〕 Ellison left the University of Illinois at Urbana–Champaign after his second year, not taking his final exams, because his adoptive mother had just died. After spending a summer in Northern California, he attended the University of Chicago for one term, where he first encountered computer design. In 1966, aged 22, he moved to Northern California. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Larry Ellison」の詳細全文を読む スポンサード リンク
