Fiorello H. La Guardia, American lawyer and politician, 99th Mayor of New York City (born 1882)

Fiorello Henry La Guardia was an American attorney and politician who represented New York in the U.S. House of Representatives and served as the 99th mayor of New York City from 1934 to 1946. He was known for his irascible, energetic, and charismatic personality and diminutive, rotund stature. An ideologically socialist member of the Republican Party, La Guardia was frequently cross-endorsed by parties other than his own, especially parties on the left under New York's electoral fusion laws. A panel of 69 scholars in 1993 ranked him as the best big-city mayor in American history.

The mayor of New York City, officially mayor of the City of New York, is head of the executive branch of the government of New York City and the chief executive of New York City. The mayor's office administers all city services, public property, police and fire protection, and most public agencies, and enforces all city and state laws within New York City.
