Read this: The Bronx has also become home to a peculiar poetic tribute, in the form of the Heinrich Heine Memorial, better known as the Lorelei Fountain from one of Heine's best-known works (1838). After Heine's German birthplace of Düsseldorf had rejected, allegedly for anti-Semitic motives, a centennial monument to the radical German-Jewish poet (1797–1856), his incensed German-American admirers, including Carl Schurz, started a movement to place one instead in Midtown Manhattan, at Fifth Avenue and 59th Street. However, this intention was thwarted by a combination of ethnic antagonism, aesthetic controversy and political struggles over the institutional control of public art.
