After Boss Tweed's profligate use of city funds, Green was brought in to return the city to fiscal responsibility and solvency (he even used his own money to cover police payroll). In 1898, [he consolidated] the five boroughs—Green was thereafter known as the "father of Greater New York."
[B]ut Green accomplished much more: he was a major reason we have the Metropolitan Museum of Art, the Museum of Natural History, the New York Public Library, and the Bronx Zoo. Riverside Park? Morningside Park? Ft. Washington Park? AHG was behind them all—truly the Greening of New York.
