Pierre Morad Omidyar is a French-born Iranian-American billionaire entrepreneur, software engineer, and philanthropist, best known as the founder of eBay, which revolutionized online auctions and marketplaces and played an early role in shaping online commerce. Born on June 21, 1967, in Paris, France, to Iranian parents who were students at the time, Omidyar moved to the United States at age six with his family, settling in the Washington, D.C. area. He displayed an early aptitude for technology, teaching himself programming and building his first computer program at age 14. Omidyar attended Tufts University, where he earned a Bachelor of Science in computer science in 1988. After graduation, he worked in software development for companies like Claris and General Magic before launching eBay in 1995 as AuctionWeb from his home in San Jose, California. The platform quickly grew, and Omidyar served as its chairman from 1998 to 2015, amassing significant wealth in the process.

Omidyar's influence extends far beyond eBay into philanthropy and media. In 2004, he and his wife, Pamela Wesley Omidyar, established the Omidyar Network, a philanthropic investment firm that has committed billions to initiatives addressing global poverty, education, human rights, and economic inclusion. His commitment to transparency and journalism led to the 2013 founding of First Look Media, which launched The Intercept as a platform for investigative reporting. Omidyar's family heritage traces back to his grandfather, General Mahmud Mir-Djalali, a prominent figure in the Imperial Iranian Army who played roles in the 1921 Pahlavi Dynasty's rise, the 1953 overthrow of Prime Minister Mohammad Mossadegh, and the development of Iran's defense industries. As of 2023, Forbes estimates Omidyar's net worth at $8.7 billion, ranking him as the 245th-richest person globally. He is also recognized for his political activism, supporting progressive causes and digital privacy efforts.
