Business Career
In 1966, Bloomberg began working at Salomon Brothers, a large investment bank on Wall Street. He was good at his job and became a partner in the company. In 1981, a new company bought Salomon Brothers, and Bloomberg was let go. He received $10 million from the company.
Using this money, Bloomberg started his own company called Innovative Market Systems. He had a big idea: he believed that Wall Street companies would pay for fast, high-quality business information delivered on computer screens. His company created a special computer terminal, now known as the Bloomberg Terminal, that gave users real-time market data and financial news.
The company, later renamed Bloomberg L.P., became a huge success. It grew to include Bloomberg News, Bloomberg Radio, and other services. As of 2019, the company employed 20,000 people in many different locations. After serving as mayor, Bloomberg returned to lead his company again.
Political Career
For most of his life, Bloomberg was a member of the Democratic Party. But in 2001, he switched parties to run for mayor of New York City as a Republican. He won the election and took office on January 1, 2002.
Mayor of New York City

As mayor, Bloomberg was known for using data and statistics to run the city. He made many changes, including:
- Public Health: He passed a ban on smoking in indoor places like restaurants and bars. He also banned unhealthy trans-fat from being used in restaurants.
- City Improvements: He added many new bicycle lanes and made parts of Times Square into plazas where people could walk freely.
- Rebuilding: After the September 11 attacks, his leadership helped rebuild parts of the city and encouraged new construction.
- Education: He worked to reform the city's public schools by creating public charter schools.
Bloomberg was re-elected in 2005. In 2007, he left the Republican Party and became an Independent. New York City had a rule that mayors could only serve two terms. Bloomberg helped change this law, which allowed him to run for a third term. He won the election in 2009 and served as mayor until the end of 2013.
One of his most debated policies was the stop-and-frisk program, which allowed police to stop and search people on the street. Many people felt the program was unfair to certain groups. A court later ruled against how the program was being used. Years later, Bloomberg apologized for supporting it.
2020 Presidential Campaign

Bloomberg had thought about running for president several times. In November 2019, he officially launched his campaign for the Democratic nomination for the 2020 election. He did not accept donations and instead used his own money, spending a record-breaking amount.
He entered the race late and did not win enough support from voters. He ended his campaign in March 2020 and endorsed Joe Biden.
Defense Innovation Board
In 2022, President Biden chose Bloomberg to be the chair of the Defense Innovation Board. This group gives advice to the U.S. military about new technology.
Philanthropy: Giving Back
Michael Bloomberg is one of the most generous people in the world. Through his foundation, Bloomberg Philanthropies, he has given away more than $17 billion. His donations focus on five main areas: the environment, public health, the arts, government innovation, and education.
Environmental Work
Bloomberg is a strong supporter of fighting climate change. He has given hundreds of millions of dollars to campaigns like Beyond Coal and Beyond Carbon. These programs work to close polluting coal power plants and promote clean energy. He also works with city leaders around the world to help them reduce pollution and protect the environment.
Health and Education
Bloomberg has donated nearly $1 billion to the World Health Organization (WHO) to promote anti-smoking efforts around the world. He also co-founded Everytown for Gun Safety, a group that works to prevent gun violence.
Education is another major focus of his giving. He has given more than $4.5 billion to his old school, Johns Hopkins University. In 2018, he gave the school a gift of $1.8 billion. This money helps the university accept students based on their talent, not on how much money their families have. He has also given large donations to support Black medical schools and students.
Personal Life
In 1975, Bloomberg married Susan Brown. They have two daughters, Emma and Georgina. The couple divorced in 1993, but they have remained friends. Since 2000, Bloomberg's partner has been Diana Taylor.
