Her career at the Metropolitan Opera began in the summer of 1910 during the Met's first visit to Paris. On June 9 of that year she replaced a singer who had become ill in the role of Manon in Puccini's Manon Lescaut. On the opening night of the 1912-13 season, she made her debut with the Met in New York when she sang Manon opposite Enrico Caruso.^[2] In 1915 she was forced to stop singing for a surgical operation to remove nodes on her vocal cords. Following a lengthy convalescence, she returned to the stage in 1921. During the course of her career with the Opera, she appeared a total of 654 times and sang the leading role in 39 operas. She was famous for her portrayals of Manon in Massenet's opera; Mimì in La bohème; Fiora in L' amore dei trè rè; Mélisande in Pelléas et Mélisande; and Violetta in La traviata.^[1][2][4][5]

Beginning late in 1932, Bori began a career as fundraiser. When the Great Depression struck, the Met continued to sell tickets to performances with no difficulty, but the contributions of its stockholders fell off dramatically and by the end of 1932 the board of directors found that a great deal of money would be needed if the next season were to be held. Early in 1933, Bori agreed to work with the Opera's managers to obtain the funds. In this work she was not a figurehead. She headed an organization called the Committee to Save the Metropolitan Opera House and, in actions that were widely reported in the press, she made appeals by flyer, letter, and in personal contacts with potential benefactors. After a personal appeal from her during a radio broadcast of Manon, she sent personal acknowledgements to the thousands of people who responded. She also traveled widely and participated in numerous benefits, at which she performed.^[1][6] During this period of fundraising, she continued to carry out an arduous schedule of performance. It took only two months to raise the $300,000 that was needed.^{[7][8][9][10][11][12][13]}

In May 1933, the chairman of the Metropolitan board publicly thanked Bori, saying she had accomplished a feat that was thought to be impossible. He said she "took command of the situation and applied to the fulfillment of the purpose in hand the same qualities of imagination and genius which have, in her own work made her one of the greatest artists of all time."^[14]

From 1933 to 1935 Bori served as chair of the "Maintain the Metropolitan" committee which had succeeded the "Save the Metropolitan" committee. To assure the viability of the 1934-35 opera season, this committee raised an amount approximately equal to the sum raised the previous year.^[15] In 1935, she was the first performer to be elected to the Board of Directors of the Metropolitan Opera Association. In joining the board she continued to sit on its opera management committee.^[16]

Her farewell gala on March 29, 1936 was one of the great events at the Metropolitan. Bori sang scenes from Manon and La traviata, with contributions from Flagstad, Melchior, Rethberg, Pinza, Ponselle, Martinelli, Tibbett and Richard Crooks.

Bori continued to perform in recitals and record for some years after her Metropolitan retirement; she can be heard, for example, in "off-the-air" recordings of a Hollywood Bowl concert from 1937, singing "Si, mi chiamano Mimì" and "O soave fanciulla" with Tenor Joseph Bentonelli, with the LA Philharmonic under Otto Klemperer. After her retirement from singing she was named chairman of the Metropolitan Opera Guild. Under her leadership the Guild collected musical instruments for military hospitals and performed other war activities as well as boosting opera throughout the country.^[7]

Bori suffered a cerebral hemorrhage on May 2, 1960, and she died in Roosevelt Hospital on May 14. She had never married, believing that artists should not do so.^[1][2][7]

Kathryn Elizabeth Smith (May 1, 1907 – June 17, 1986), known professionally as Kate Smith and The First Lady of Radio, was an American singer, a contralto, best known for her rendition of Irving Berlin's "God Bless America".

She had a radio, television, and recording career spanning five decades, which reached its pinnacle in the 1940s. Smith became known as The Songbird of the South after her enduring popularity during World War II and contribution to American culture and patriotism.
