#19 Sergey Brin- Net Worth $29 Billion $448 M | -1.5% As of 4/12/2014

Sergey Brin's fortune passed the $30 billion mark for the first time recently as shares in the Mountain View, Calif.-based search giant's stock reached new heights. Shares are up nearly 50% year-over-year as of mid-Feb. 2014, leading to a more than $7 billion since last year's Forbes Billionaires list. Confining himself to a more background role, Brin lets Page run the show as CEO while he oversees the secretive Google X division, dedicated to breakthrough "moonshots" like driverless cars and Glass, the augmented-reality spectacles he wears everywhere. In April 2014, Google will undergo a stock split to introduce new Class C shares that will carry no voting power. That move will consolidate the voting power of executives including Brin, who owns more than 23 million Class B shares, which carry 10-to-one voting power. News broke in August that he and his wife of six years, Anne Wojcicki, separated and that Brin was involved with another Google employee. He and Wojcicki donated $53 million to the Michael J. Fox Foundation in February as part of the Brin-Wojcicki challenge to fight Parkinson's disease.
