Celebrated soprano (1820-1887), known as the 'Swedish Nightingale,' who, under the management of P. T. Barnum, became the most renowned and highly paid singer of her day. Two ALSs, signed "Jenny L. Goldschmidt" and "J. L. Goldschmidt," totaling six pages on two sets of adjoining sheets, March 20, [no year], and July 31, [1885]. The first, about dining with Clara Schumann, in part: "Should you happen to be disengaged tomorrow and care to come and dine with us at 7 o'clock to meet Mme. Schumann we would be happy to see you"; the second, to a pupil giving her philosophy of singing, in part: "With my enormous experience and a life’s study I ought to be able to bring out singers—for I am convinced that only when teachers can sing and show their pupils what they ought to do can real art be produced. Singing is as much moral and mental as it is mechanical. It is a combination of those qualities which alone can form the Master and her Pupil." In overall fine condition, with light soiling to the first page of the longer letter. Important musical content from the revered soprano.
