Sergey Mikhailovich Brin was born in Moscow to Michael and Eugenia Brin, both Jewish graduates of Moscow State University. His father was a mathematician, and his mother a researcher. The Brin family faced antisemitism in the Soviet Union, fueling their desire to emigrate.

Facing increasing societal and professional limitations due to their Jewish heritage, the Brin family emigrated to the United States when Sergey was six years old. This move provided Sergey with access to better educational opportunities and a less restrictive environment to pursue his intellectual interests.

Sergey enrolled at the University of Maryland, College Park, to study mathematics and computer science, graduating with a Bachelor of Science degree with honors in 1993. During his time at Maryland, he actively engaged in research and demonstrated a strong aptitude for problem-solving and data analysis, laying the groundwork for his future endeavors.

Sergey began his graduate studies in computer science at Stanford University, where he focused on data mining and search technologies. This marked a pivotal point in his career, leading him to connect with Larry Page and embark on the journey of building a groundbreaking search engine.

At Stanford, Sergey met Larry Page. Their collaboration on a research project initially called "BackRub" aimed to improve the relevance of search results by analyzing the backlinks of web pages. This innovative approach was the precursor to Google's PageRank algorithm, which became its core differentiating factor.

Recognizing the immense potential of their technology, Sergey Brin and Larry Page officially founded Google in a garage in Menlo Park, California. The company's mission was to organize the world's information and make it universally accessible and useful. They secured initial funding from angel investors and began building a team to support their vision.

Google went public with its initial public offering (IPO) in August 2004. The IPO was a significant milestone, marking the transition of Google from a startup to a major publicly traded company. This influx of capital further fueled Google's expansion into new areas and technologies.

Google underwent a major restructuring to form Alphabet Inc., a holding company with Google as its primary subsidiary. This restructuring allowed Google to focus on its core business (internet products) while separating out other ventures such as life sciences (Verily), self-driving cars (Waymo), and venture capital (GV) under the Alphabet umbrella. Brin became the President of Alphabet.

Sergey Brin stepped down from his role as President of Alphabet, along with Larry Page stepping down as CEO. Sundar Pichai, the CEO of Google, assumed the CEO role at Alphabet as well. While Brin and Page remained on the Alphabet board of directors, this marked a significant shift in the day-to-day leadership of the company.

While no longer in a daily leadership role, Sergey Brin remains a major shareholder and member of the board of directors of Alphabet. He continues to be involved in various projects and technological advancements. Additionally, he dedicates a portion of his time and resources to philanthropic efforts, including research into Parkinson's disease, which his mother was diagnosed with.
