Michael Bloomberg

Philanthropist

Billionaire businessman and philanthropist Michael Bloomberg served 12 years as Mayor of New York City. During his 2001-2013 term, he reimagined the landscape and waterfront of the city with an unprecedented expansion of public parks, and permanently altered the skyline with zoning changes that made way for a building boom. His public-health initiatives--a bar and restaraunt smoking ban, an attempt to curtail soda drinking, and the Citi bike program and bike lane expansion--divided residents but coincided with a life expectancy increase of 3 years in the city. Bloomberg is the founder of global data and media company Bloomberg LP and Bloomberg Philanthropies, through which he's donated billions to a variety of causes in five areas of focus: arts and culture, education, the environment, government innovation, and public health.
