Carlo Galeffi (June 4, 1884 – September 22, 1961) was a leading Italian baritone, particularly associated with the operatic works of Giuseppe Verdi and the various verismo composers.
Galeffi was born in Malamocco (Venice). As a youth, he studied with Di Como and Sbriscia, later with Antonio Cotogni. According to The Concise Oxford Dictionary of Opera, he made his professional debut in 1904, aged 21, at Rome's Teatro Adriano, as Enrico in Lucia di Lammermoor. Galeffi sang throughout Italy before reaching Italy's premier opera house, La Scala, Milan, in 1912. He would remain at La Scala until 1938, becoming a favorite of the conductor Arturo Toscanini.
Galeffi made his American debut in Boston in 1910. He sang at the New York Metropolitan Opera only once, on November 29 of that same year, as Verdi's Germont père in La Traviata. Galeffi sang, too, at the Lyric Opera of Chicago from 1919 to 1921, and also appeared in South America on a number of occasions.
The bulk of Galeffi's career, however, took place in Italy, especially at La Scala, where he was much acclaimed for his performances of Verdi roles that ranged from Nabucco, through Renato, Di Luna, Amonasro and Simon Boccanegra, to Iago. Other parts that he sang included Tell in Rossini's Guglielmo Tell, Douglas in Mascagni's Guglielmo Ratcliff, Scarpia in Puccini's Tosca, Tonio in Leoncavallo's Pagliacci, Gerard in Giordano's Andrea Chénier, Amfortas in Wagner's Parsifal and Telramund in Wagner's Lohengrin.
