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. Lind donated her profits to her favoured charities, principally the endowment of free schools in her native Sweden.

Johanna Maria Lind (Madame Goldschmidt) (6 October 1820 – 2 November 1887) was a Swedish opera singer, often called the "Swedish Nightingale". One of the most highly regarded singers of the 19th century, she performed in soprano roles in opera in Sweden and across Europe, and undertook an extraordinarily popular concert tour of the United States beginning in 1850. She was a member of the Royal Swedish Academy of Music from 1840.
