Sergey Mikhaylovich Brin (Russian: Серге́й Миха́йлович Брин; born August 21, 1973) is an American computer scientist and internet entrepreneur. Together with Larry Page, he co-founded Google. Brin is the President of Google's parent company Alphabet Inc. As of October 2018, Brin is the 13th-richest person in the world, with an estimated net worth of US$50.6 billion.Brin immigrated to the United States with his family from the Soviet Union at the age of 6. 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 later became friends. They crammed their dormitory room with inexpensive computers and applied Brin's data mining system to build 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.The Economist referred to Brin as an "Enlightenment Man", and as someone who believes that "knowledge is always good, and certainly always better than ignorance", a philosophy that is summed up by Google's mission statement, "Organize the world's information and make it universally accessible and useful", and its unofficial yet sometimes controversial motto, "Don't be evil".Through his 8 year marriage to Anne Wojcicki, the founder of 23andme, he was the brother-in-law of Susan Wojcicki, the CEO of YouTube.
