The month of May is American Jewish History Month, so for this entire month I will continue share the stories of important Jewish figures in American finance. Today, I will discuss Michael Bloomberg who is an American businessman and politician. He is the majority owner and co-founder of Bloomberg L.P. He also served as the 108th mayor of New York City for three terms and was a candidate for the 2020 Democratic nomination for president of the United States.
Michael Bloomberg, born on February 14, 1942, in Medford, Massachusetts. Bloomberg's paternal grandfather, Rabbi Alexander "Elick" Bloomberg, was a Polish Jew and his maternal grandfather, Max Rubens, was a Lithuanian Jewish immigrant from present-day Belarus and his maternal grandmother was born in New York to Lithuanian Jewish parents.
Bloomberg earned a degree in engineering from Johns Hopkins University and later obtained an MBA from Harvard Business School. Bloomberg began his career at Salomon Brothers, a Wall Street investment bank, where he quickly rose through the ranks. However, after the firm was acquired in 1981, he was let go, receiving a $10 million severance package. He used this money to launch Bloomberg LP, a financial data and media company that revolutionized the industry.
Bloomberg LP became a global leader in financial information services, largely due to the Bloomberg Terminal, which provided real-time financial data and analytics to investors and traders. The company expanded into news, television, and radio, solidifying Bloomberg’s influence in finance. His success in business made him one of the wealthiest individuals in the world, with an estimated net worth of $104.7 billion as of 2025.
Beyond his business achievements, Bloomberg served as the mayor of New York City from 2002 to 2013, implementing policies that emphasized data-driven governance. He later ran for the Democratic nomination for president in 2020. His philanthropic efforts have also been significant—he has donated over $17 billion to various causes, including public health, climate change, and education.
Bloomberg’s impact on finance is immense. His company transformed how financial professionals access and analyze data, making markets more efficient. His leadership style, combining business acumen with technological innovation, has shaped modern financial services. His contributions extend beyond finance into politics and philanthropy, making him one of the most influential figures of his generation.
