Becoming CEO Of Bloomberg

After growing up in Medford, Massachusetts, Michael Bloomberg attended Johns Hopkins University, where he obtained a degree in electrical engineering. In 1966, after graduating from college, he began his career at the securities brokerage Salomon Brothers. He was earning a salary of $9,000 a year. Micheal got quickly promoted to equities desk, and in 1972 became a general partner at Salamon Brothers.

In a twist of events, in 1981, Micheal was fired after Phibro Corporation bought Salomon Brothers. His luck was that he got paid $10 million for his equity in the firm.  

Bloomberg decided to make good use of the money and skills acquired in the first 15 years of his career. He set up a data services company named Innovative Market Systems (IMS), which was renamed Bloomberg L.P. in 1986. In his mind, Wall Street was ready to pay a premium for high-quality business information.

Previously, in August 2010, he signed The Giving Pledge to give away at least half of his wealth. Following that, he has given away $9.5 billion overall.

In his words: “I am a big believer in giving it all away and have always said that the best financial planning end with bouncing the check to the undertaker”.  

And “If you want to do something for your children and show how much you love them, the single best thing – by far – is to support organizations that will create a better world for them and their children. And by giving, we inspire others to give of themselves, whether their money or their time.”
