Well, to make a long story short, Larry Ellison is Jewish!
Since Larry Ellison's mother is Jewish, and in Orthodox Judaism and Conservative Judaism, those with a Jewish mother (or those who underwent a halakhic conversion) are considered Jewish, then that makes him Jewish. His father is not Jewish.
Larry Ellison (whose full birth name is Lawrence Joseph Ellison) was born on August 17, 1944 in Lower East Side, Manhattan, New York, U.S..
He is best known as the co-founder and chief executive officer of Oracle Corporation, an enterprise software company. In 2013, Forbes listed him as the third-wealthiest man in America.
