Title: CEO, Bloomberg lp Country: US Age: 73
After leaving Bloomberg in 1981, and spending twelve years as mayor of New York City, Bloomberg has made waves by returning to his company as the figurehead. His return brought several layoffs, management shakeups, and a website relaunch. The man with a fortune worth $42 billion is once again at the center of revolutionizing the distribution of financial information.
The man is effectively responsible for instituted a smoking ban in New York City, although the efforts fizzled out last year. Bloomberg has also pledged $50 million to combat gun violence through the Everytown for Gun Safety organization.
