Michael Bloomberg was born in Boston, to a Jewish family of immigrant heritage: his paternal grandfather Elick Bloomberg came from Russia at the end of the XIX century, and his maternal grandfather Max Rubens came from present-day Belarus, when it was still part of the Russian Empire.
Bloomberg graduated from Johns Hopkins University in 1964 with a Bachelor of Science degree in electrical engineering, but then decided to change his line of expertise and entered the Harvard Business School, where he got his MBA!
In 1973, Bloomberg became a general partner at Salomon Brothers of Wall Street where he dealt with equity trading and systems development. In 1981 he was laid off, but given a sizable ($10 million) severance package, which he effectively used to create his own company Innovative Market Systems, that capitalized on the need of the Wall Street for high quality business information, delivered as quickly as possible, and in a usable form - created the famous Bloomberg terminal system. Their first client was Merrill Lynch, which had Bloomberg install 22 of the Market Master terminals. Just eight years later, there were 8,000 of such terminals working across the country...
Since then, Bloomberg has become one of the richest Americans. He owns at least 13 properties around the world, and is near the top of a waiting list for a personal AW609 tiltrotor aircraft. But at the same time, he is one of the most charitable Americans: his Bloomberg Philanthropies Foundation donated or pledged close to $1.2 billion!
In 2002 Bloomberg became the 108th Mayor of New York City, winning the re-election in 2005, and then again in 2009, setting a record.
He became (in)famous by applying a statistical, results-based approach to city management, by granting city commissioners wide autonomy, and by going against the 190-year tradition, when he instituted Wall Street trading floor-like meetings with dozens of staff gathered in a large chamber for an open discussion - for greater transparency and efficiency.
In addition, his views on domestic and homeland security issues made him unpopular among conservatives and liberals alike. On the one hand, he insisted that deporting 12 million illegal aliens was unrealistic and "fiction", and on the other hand, supported a federal ID and DNA database for illegals, as well as a strict immigration reform suggested by John McCain.
Bloomberg was married to Susan Brown, who brought him two daughters: Emma and Georgina, featured in the Born Rich documentary about the children of the extremely wealthy. Since 2010, Bloomberg has been living with Diana Taylor.
In 2014, Queen Elizabeth II named Bloomberg an honorary Knight Commander of the Order of the British Empire. He cannot use the traditional title "Sir", but may add letters "KBE" after his name in official documents, which he rarely, if ever, does.
