Sergey Mikhailovich Brin is an American business magnate who co-founded Google with Larry Page. Brin was the president of Google's parent company, Alphabet Inc., until stepping down from the role on December 3, 2019. He and Page remain at Alphabet as co-founders, controlling shareholders, board members and employees. As of February 2023, Brin is the 9th-richest person in the world, with an estimated net worth of $89.0 billion.

Brin emigrated to the United States from the Soviet Union at the age of six. He earned his bachelor's degree at the University of Maryland, College Park, following in his father's and grandfather's footsteps by studying mathematics as well as computer science. After graduation, he enrolled in Stanford University to acquire a PhD in computer science. There he met Page, with whom he built a web search engine. The program became popular at Stanford, and they suspended their PhD studies to start up Google in Susan Wojcicki's garage in Menlo Park.

Early life and education

Brin was born on August 21, 1973, in Moscow in the Soviet Union, to Russian Jewish parents, Mikhail and Eugenia Brin, both graduates of Moscow State University (MSU). His father is a retired mathematics professor at the University of Maryland, and his mother a researcher at NASA's Goddard Space Flight Center.

The Brin family lived in a three-room apartment in central Moscow, which they also shared with Sergey's paternal grandmother. In 1977, after his father returned from a mathematics conference in Warsaw, Poland, Mikhail Brin announced that it was time for the family to emigrate. They formally applied for their exit visa in September 1978, and as a result, his father was "promptly fired". For related reasons, his mother had to leave her job. For the next eight months, without any steady income, they were forced to take on temporary jobs as they waited, afraid their request would be denied as it was for many refuseniks. In May 1979, they were granted their official exit visas and were allowed to leave the country.

The Brin family lived in Vienna and Paris while Mikhail Brin secured a teaching position at the University of Maryland with help from Anatole Katok. During this time, the Brin family received support and assistance from the Hebrew Immigrant Aid Society. They arrived in the United States on October 25, 1979.

Brin attended elementary school at Paint Branch Montessori School in Adelphi, Maryland, but he received further education at home; his father, a professor in the department of mathematics at the University of Maryland, encouraged him to learn mathematics and his family helped him retain his Russian-language skills. He attended Eleanor Roosevelt High School, Maryland. In September 1990, Brin enrolled in the University of Maryland, where he received his Bachelor of Science from the Department of Computer Science in 1993 with honors in computer science and mathematics at the age of 19. In 1993, he interned at Wolfram Research, the developers of Mathematica.

Brin began his graduate study in computer science at Stanford University on a graduate fellowship from the National Science Foundation, receiving a M.S. in computer science in 1995. As of 2008, he was on leave from his PhD studies at Stanford.

Search engine development

During an orientation for new students at Stanford, he met Larry Page. The two men seemed to disagree on most subjects, but after spending time together they "became intellectual soul-mates and close friends." Brin's focus was on developing data mining systems while Page's was on extending "the concept of inferring the importance of a research paper from its citations in other papers". Together, they authored a paper titled "The Anatomy of a Large-Scale Hypertextual Web Search Engine".

To convert the backlink data gathered by BackRub's web crawler into a measure of importance for a given web page, Brin and Page developed the PageRank algorithm, and realized that it could be used to build a search engine far superior to those existing at the time. The new algorithm relied on a new kind of technology that analyzed the relevance of the backlinks that connected one Web page to another, and allowed the number of links and their rank, to determine the rank of the page. Combining their ideas, they began utilizing Page's dormitory room as a machine laboratory, and extracted spare parts from inexpensive computers to create a device that they used to connect the nascent search engine with Stanford's broadband campus network.

After filling Page's room with equipment, they then converted Brin's dorm room into an office and programming center, where they tested their new search engine designs on the web. The rapid growth of their project caused Stanford's computing infrastructure to experience problems.

Page and Brin used the former's basic HTML programming skills to set up a simple search page for users, as they did not have a web page developer to create anything visually elaborate. They also began using any computer part they could find to assemble the necessary computing power to handle searches by multiple users. As their search engine grew in popularity among Stanford users, it required additional servers to process the queries. In August 1996, the initial version of Google was made available on the Stanford Web site.

Other interests

Brin's family office with ex-wife Wojcicki, Bayshore Global Management, oversees over $100 billion in assets and manages his secretive $5 billion charitable foundation.

In June 2008, Brin invested $4.5 million in Space Adventures, the Virginia-based space tourism company.

Brin and Page jointly own a customized Boeing 767-200 and a Dassault/Dornier Alpha Jet, and pay $1.3 million a year to house them and two Gulfstream V jets owned by Google executives at Moffett Federal Airfield. The aircraft have had scientific equipment installed by NASA to allow experimental data to be collected in flight.

Awards and accolades

2002-2009

In 2002, Brin, along with Larry Page, was named in the MIT Technology Review TR100, as one of the top 100 innovators in the world under the age of 35.
In 2003, both Brin and Page received an honorary MBA from IE Business School "for embodying the entrepreneurial spirit and lending momentum to the creation of new businesses...".
In 2003, Brin and Page were both Award Recipients and National Finalists for the EY Entrepreneur of the Year Award.
In 2004, they received the Marconi Foundation Prize, the "Highest Award in Engineering", and were elected Fellows of the Marconi Foundation at Columbia University. "In announcing their selection, John Jay Iselin, the Foundation's president, congratulated the two men for their invention that has fundamentally changed the way information is retrieved today."
In 2004, Brin received the American Academy of Achievement's Golden Plate Award with Larry Page at a ceremony in Chicago, Illinois.

2009-present

In November 2009, Forbes named Brin and Page the fifth most powerful people in the world.
Earlier that same year, in February, Brin was inducted into the National Academy of Engineering, which is "among the highest professional distinctions accorded to an engineer ... [and] honors those who have made outstanding contributions to engineering research, practice...". He was selected specifically, "for leadership in development of rapid indexing and retrieval of relevant information from the World Wide Web".
In their "Profiles" of Fellows, the National Science Foundation included a number of earlier awards:

he was a featured speaker at the World Economic Forum and the Technology, Entertainment and Design Conference. ... PC Magazine has praised Google in the Top 100 Web Sites and Search Engines (1998) and awarded Google the Technical Excellence Award, for Innovation in Web Application Development in 1999. In 2000, Google earned a Webby Award, a People's Voice Award for technical achievement, and in 2001, was awarded Outstanding Search Service, Best Image Search Engine, Best Design, Most Webmaster Friendly Search Engine, and Best Search Feature at the Search Engine Watch Awards.

As of October 2022, Brin is the 8th-richest person in the world according to Forbes, with an estimated net worth of $83.8 billion.
