Celebrated soprano (1820–1887), known as the Swedish Nightingale, who, under the management of impresario P. T. Barnum, became the most renowned and highly paid singer of her day. Her 1850 singing engagement in Washington, D.C. was attended by the justices of the Supreme Court, and the excitement her visit generated led to the adjournment of Congress.
