Sergey Mikhaylovich Brin is an American computer scientist and internet entrepreneur who, together with Larry Page, co-founded Google, one of the most profitable Internet companies. As of June 2014, his personal wealth was estimated to be US$ 30 billion. Together, Brin and Page each own about 16 percent of the company. Brin emigrated to the United States with his family from the Soviet Union at the age of six. He earned his undergraduate degree at the University of Maryland, following in his father's and grandfather's footsteps by studying mathematics, as well as computer science. After graduation, he moved to Stanford University to acquire a PhD in computer science. There he met Larry Page, with whom he later became friends. They crammed their dormitory room with inexpensive computers and applied Brin's data mining system to build a search engine. The program became popular at Stanford and they suspended their PhD studies to start up Google in a rented garage. [More at Wikipedia]
