Michael Rubens Bloomberg (born February 14, 1942) is a businessman and Mayor of New York City.
Bloomberg was born and raised in Medford, Massachusetts, a suburb of Boston. He made his fortune selling financial-information terminals to Wall Street firms. Bloomberg L.P. also began a radio network (the flagship station is 1130 WBBR-AM in New York City). Prior to founding the company, he was general partner at Salomon Brothers, where he headed equity trading, sales and, later, systems development.
In 2001 he was elected mayor, succeeding Rudy Giuliani, who was required to leave office by term limits. Bloomberg, a lifelong Democrat, ran for mayor as a Republican, reportedly to avoid the crowded field in the Democratic primary. He defeated Herman Badillo in the Republican primary and Democratic candidate Mark J. Green in the general election.
Michael Bloomberg is a member of the Phi Kappa Psi fraternity. He graduated from Johns Hopkins University in 1964 with a BS in electrical engineering and Harvard University with a Master of Business Administration degree. Bloomberg has since donated $100 million to Johns Hopkins University.
Bloomberg has supported a number of measures to restrict public smoking during his time as mayor.
Mr. Bloomberg is among of the world's richest 600 or so people, with a net worth of close to $4 billion. He is founder and CEO of the financial news and information services company, Bloomberg LP. His business empire employs 7,000 people.
