"The Nightingale" (Danish: "Nattergalen") is a literary fairy tale written by Danish author Hans Christian Andersen about an emperor who prefers the tinkling of a bejeweled mechanical bird to the song of a real nightingale.
 When the Emperor is near death, the nightingale's song restores his health.
 Well received upon its publication in Copenhagen in 1843 in "New Fairy Tales", the tale is believed to have been inspired by the author's unrequited love for opera singer Jenny Lind, the "Swedish nightingale".
 The story has been adapted to opera, ballet, musical play, television drama and animated film.

The Swedish soprano Jenny Lind, often known as the "Swedish Nightingale" was one of the most highly regarded singers of the 19th century.
 At the height of her fame she was persuaded by the showman P. T. Barnum to undertake a long tour of the United States.
 The tour began in September 1850 and continued to May 1852.
 Barnum's advance publicity made Lind a celebrity even before she arrived in the U.S., and tickets for her first concerts were in such demand that Barnum sold them by auction.
 The tour provoked a popular furore dubbed "Lind Mania" by the local press, and raised large sums of money for both Lind and Barnum.
