Harry Gustaf Nikolai Gädda, better known as Nicolai Gedda, was a Swedish operatic tenor. Debuting in 1951, Gedda had a long and successful career in opera until the age of 77 in June 2003, when he made his final operatic recording. Skilled at languages, he performed operas in French, Russian, German, Italian, English, Czech and Swedish, as well as one in Latin. In January 1958, he created the part of Anatol in the world premiere of the American opera Vanessa at the Metropolitan Opera. Having made some two hundred recordings, Gedda is one of the most widely recorded opera singers in history. His singing is best known for its beauty of tone, vocal control, and musical perception.

Vanessa is an American opera in three acts by Samuel Barber, opus 32, with an original English libretto by Gian Carlo Menotti. It was composed in 1956–1957 and was first performed at the Metropolitan Opera in New York City on January 15, 1958 under the baton of Dimitri Mitropoulos in a production designed by Cecil Beaton and directed by Menotti. Barber revised the opera in 1964, reducing the four acts to the three-act version most commonly performed today.
