9. Sergey Brin – $29.2 billion
Sergey Brin is an American computer scientist and internet entrepreneur who, together with Larry Page, co-founded Google, one of the most profitable Internet companies. 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”.
As stated by Forbes: “Google cofounder Sergey Brin runs Google X, the secretive division of the search engine company that focuses on risky projects, such as smart contact lenses, airborne wind turbines and the ill-fated Google Glass. In January 2015, Google announced it would stop making the current version of the augmented reality spectacles, which had become Brin’s signature accessory and were slated to be sold commercially. Brin made headlines in the fall of 2013 for his affair with a 27-year old Google executive, which caused him to separate from wife Anne Wojcicki and reportedly sparked a rift with Page. The son of two academics, Brin emigrated to the U.S. from Moscow when he was six. He founded Google with Page in 1998, when they were both computer science Ph.D. students at Stanford University.”
