For over a decade, he served as New York City mayor earning only $US1 dollar a year. Before that, he made billions through the company he founded, Bloomberg LP, and its Bloomberg Terminal financial software.
Here’s everything we know about his fortune, shiny toys, good and bad habits, and leading ladies.
Meet Michael Bloomberg: America's eighth richest person, founder of Bloomberg LP, philanthropist, and former New York City mayor.
Bloomberg grew up in Medford, Massachusetts, a suburb of Boston. He went to Johns Hopkins University for mechanical engineering and received a MBA from Harvard University.
After reaching partner at Solomon Brothers, he was later in charge of IT. When Solomon merged with Phibro, they let Bloomberg go. He then created Bloomberg LP, a financial services and media company worth a reported $27.7 billion, due in large part to the success of the Bloomberg Terminal.
Personally and through his foundation, Bloomberg Philanthropies, he has donated $3 billion to a variety of charitable causes.
He recently donated $100 million to Cornell's new technology campus, rising on New York's Roosevelt Island.
Though he has returned to the head of his eponymous company, he was away for a period of 12 years while serving as mayor of New York City. He took office in 2002 -- earning a $1 per year salary -- and helped rebuild the city after 9/11.
As for real estate, Bloomberg is said to own between 12 and 15 houses around the world. His home base is a five-story townhouse on Manhattan's Upper East Side. He also owns the building next door, as well as another condo in NYC.
Just outside of the city, he owns two houses in Westchester County's North Salem. Adjacent to the $3.6 million equestrian estate he bought for his daughter, Georgina, in 2001 is a $4.55 million home he purchased in 2012. The former has an indoor riding ring and 20 beautiful acres.
