Sergey Brin (born August 21, 1973, in Moscow, Soviet Union) is a co-founder of Google, Inc., the world’s largest Internet company, based on its search engine and online advertising technology. Forbes ranks him as the 26th richest person in the world. (in 2009)

Brin immigrated to the United States at the age of six. Earning his undergraduate degree at the University of Maryland, he followed in his father's and grandfather's footsteps by studying mathematics, double-majoring in computer science. After graduation, he moved to Stanford to acquire a Ph.D in computer science. There he met Larry Page, who quickly became his intellectual soul-mate and close friend. They crammed their dormitory room with inexpensive computers and applied Brin’s data mining system to build a superior search engine. The program became popular at Stanford and they suspended their Ph.D studies to start up Google in a rented garage.

The Economist magazine referred to Brin as “Enlightenment Man," and someone who believes that “knowledge is always good, and certainly always better than ignorance," a philosophy which is summed up by Google’s motto of making all the world’s information "universally accessible and useful."
