Michael 'Mike' Rubens Bloomberg is an American businessman, the self-made billionaire Founder, Owner, and Executive of Bloomberg L.P., the global financial information and media giant, and former Mayor of New York City. Born in Boston, Massachusetts, in 1942, his career is rooted in engineering, finance, and public service.

Bloomberg holds a B.S. in Electrical Engineering from Johns Hopkins University (1964) and an MBA from Harvard Business School (1966). His philosophical commitment centers on data-driven decision-making, technological efficiency, and high-impact philanthropy (focusing on climate change and public health).

• Bloomberg L.P. (Founder, Owner & Executive): The core private asset, the global leader in financial data terminals, news, and media (generating over $13 billion in annual revenue).
• Political Role: He served three terms as the 108th Mayor of New York City (2002–2013).
• M&A Apex: He was a Partner at Salomon Brothers before founding his company (leaving with a $10 million severance after the firm was acquired).
• Philanthropy: He is a Giving Pledge signatory and has committed over $14 billion to climate change, public health, and gun control (via Bloomberg Philanthropies).

Michael Bloomberg's strategic genius was his unwavering belief in the value of real-time, curated financial data. After being forced out of Salomon Brothers with a $10 million severance in 1981, he founded Innovative Market Systems (later Bloomberg L.P.), launching the Bloomberg Terminal—a structural innovation that transformed Wall Street trading.

His structural contribution is immense: pioneering the specialized financial data market and providing transformative political leadership (serving three terms as NYC Mayor). He returned to lead Bloomberg L.P. in 2014 after his mayoralty ended. His wealth is secured by the colossal, long-term, stable profitability of Bloomberg L.P. (which he owns 88 percent of).

Michael Bloomberg is one of the world's largest philanthropists and a Giving Pledge signatory. His structural social impact is tied to his mayoral legacy (in public health, urban planning, and education reform) and the $14 billion+ commitment of Bloomberg Philanthropies (focusing on global public health, gun control, and climate change). His investment in data-driven policy is a major structural contribution to modern governance.

His structural contribution is tied to his belief in technology and data as foundational tools for societal problem-solving.

Michael Bloomberg maintains the professional, pragmatic style of a corporate executive. His attire is consistently formal and high-quality, favoring tailored suits. His aesthetic reflects serious authority and stability, typical of a leader in the global financial and political sectors.

Residing in New York City and Bermuda, his luxury is the immense security and financial reward derived from his multi-billion dollar fortune. His life is dedicated to data governance, political advocacy, and global philanthropy.
