U.S. Post Office, Prospect Park West Station, 1961. Formerly Ninth Avenue, this street became Prospect Park West in 1895 when residents, sick of having their mail mis-delivered, petitioned the Board of Aldermen for a name change. The Brooklyn Daily Eagle described Brooklyn’s confusing lack of a street naming convention: “Let us look at the case of Ninth avenue alone. There are in Brooklyn, beside an avenue bearing this number, a Ninth street, a North Ninth street, and a South Ninth street. In New York there are Ninth avenue, and East Ninth street and West ninth street. There are seven streets with the same number and distinguished from each other only by use of the word avenue instead of street or by prefixing one of the points of the compass. It is surprising there are not a Northwest Ninth street and a Southeast Tenth avenue.”
