Sergey Brin

Early Life and the Family's Emigration

Sergey Brin was born on 21 August 1973 into a Jewish family in Moscow, Soviet Union. His father, Michael Brin, graduated with honours from the mathematics and mechanics faculty of Moscow State University but was systematically blocked by the Soviet system from pursuing graduate study or a research career because of his Jewish identity; his mother, Eugenia, was a research scientist. In 1978 the family formally applied for exit visas, and his father was promptly dismissed from his job as a result. In 1979 the Brins emigrated to the United States — among the relatively few Jewish families permitted to leave the USSR during the Brezhnev era — and settled in Maryland, where his father later became a mathematics professor at the University of Maryland and his mother a researcher at NASA's Goddard Space Flight Center.

Education and the Founding of Google

After earning a bachelor's degree in mathematics and computer science from the University of Maryland, Brin enrolled in the computer science PhD programme at Stanford University, where he met Larry Page during a campus visit in 1995. The two collaborated on an algorithm that ranked search results by analysing the link structure of web pages, initially named 'BackRub.' In September 1998, after receiving early funding that included a $100,000 cheque from Sun Microsystems co-founder Andy Bechtolsheim, they formally founded Google in a friend's garage, with Brin serving as President of Technology. Google's search algorithm proved highly accurate, and the company grew rapidly into the world's largest internet search engine.

Changes in Corporate Role

In 2001, Google hired Eric Schmidt as Chief Executive Officer, and the company was thereafter jointly run by Schmidt, Page, and Brin. In 2011, Page resumed the role of CEO, and Brin became Director of Special Projects, overseeing the company's experimental research division known as Google X (later dubbed the 'moonshot factory'), which drove forward-looking projects including self-driving cars — later spun off as Waymo — and Google Glass. In August 2015, Google underwent a corporate restructuring that created the holding company Alphabet, with Brin becoming President and Page becoming CEO. In December 2019, both Brin and Page stepped down from their management roles at Alphabet, with Sundar Pichai taking over as CEO of both Alphabet and Google; Brin has since remained a co-founder, board member, and controlling shareholder of the company.

2010: Withdrawing from the Chinese Market

In 2010, following the discovery that Google's systems had been targeted by cyberattacks originating from China, Brin stated publicly that the company could no longer operate under censorship, and was central to Google's decision to announce the end of filtering for Chinese search results and ultimately to redirect google.cn to Hong Kong servers. Brin has on multiple occasions referred publicly to his experience growing up in the Soviet Union as having given him first-hand understanding of information control; this background was widely cited in accounts of the 2010 decision.

Recent Return: Committing to AI Development

In late 2022, OpenAI's launch of ChatGPT triggered intense internal alarm at Google over the competitive threat in artificial intelligence. CEO Sundar Pichai reportedly declared an internal 'code red,' and Brin and Page were called back to help. Brin subsequently began returning to the office three to four days a week, becoming deeply involved in the development of Google's Gemini AI model, leading weekly research discussions and taking part in key hiring decisions. In May 2023, Google formally unveiled Gemini at its developer conference. Brin later said publicly that remaining retired "would have been a big mistake."
