Life and work
His professional journey started at Salomon Brothers, and then in 1981 he established his own enterprise.[3] The enterprise he founded, Bloomberg L.P., operates as a media, software, and financial information company, with its Bloomberg Terminal being its most recognized product.[3] Up until 2001, Bloomberg had always been a Democrat; that year he changed his affiliation to the Republican Party in order to seek the mayoralty.[2] The 2001 election resulted in Bloomberg becoming the 109th mayor of New York City, and he subsequently won re-election for two additional terms.[4]
During his mayoral tenure, Bloomberg backed public health measures, gun control, the creation of public charter schools, and the renovation of city infrastructure.[5] Having committed to the Giving Pledge, Bloomberg's lifetime philanthropic donations had reached $24.5 billion by 2025.[3]
