Created by Samuel Ruggles as a haven for wealthy New Yorkers, both Gramercy Park and Union Square have been among Manhattan's most desirable neighborhoods for more than 150 years. From writers and artists to powerful politicians, illustrious figures like O. Henry, Andy Warhol, Samuel Tilden and Joseph Kennedy have walked its streets. The National Arts Club and the Players Club attract patrons from around the city who are in search of a taste of grander times. Tourists flock to historic sites like the Theodore Roosevelt House, the Gramercy Park Historic District and the picturesque Union Square Park. Local tour guide Alfred Pommer and coauthor Joyce Pommer reveal the stories on the streets of the neighborhoods.
