The 108th mayor of New York City

He is also the founder of Bloomberg L.P., an information services, news, and media company. In 1966, Bloomberg was hired by Salomon Brothers to work on Wall Street. He left in 1981 after Salomon was acquired by another company and used his stake from the Salomon sale to start his own company, creating a financial information computer that would collect and analyze different combinations of past and present securities data and deliver it immediately to the user.

In 1982, Bloomberg L.P. sold 20 subscriptions to its service; 20 years later, Bloomberg L.P. had 165,000 subscribers and counting. Bloomberg L.P. now employs 8,000 people—including 2,500 in New York City—in more than 100 offices worldwide.

Bloomberg has dedicated much time and energy to philanthropic and civic affairs and has served on the boards of many organizations.
