933 performances in 55 roles. It was at the Met in 1913 that he appeared in the title role of Boris Godunov in the American premiere of Mussorgsky's opera. Didur created the roles in three operas by Giacomo Puccini at the Met, La fanciulla del West and the Il tabarro and Gianni Schicchi of the Il Trittico trilogy. He also appeared at the world premiere of Humperdinck's Die Königskinder. His other important "firsts" at the Met include the US premieres of Mozart's Così fan tutte, Smetana's The Bartered Bride, Borodin's Prince Igor (singing both Prince Galitzky and Khan Konchak), and Montemezzi's L'amore dei tre re. He also sang under the baton of Gustav Mahler in Mozart's Le nozze de Figaro, Smetana's The Bartered Bride and the Met premiere of Tchaikovsky's The Queen of Spades. Didur's last appearance at the Met was in the role of Coppélius in Les Contes d'Hoffmann on 11 February 1932. His voice had been on the wane for some time and he returned to live in Europe.

After her death he married the French dancer Marguerite Vignon in 1928. Legacy Didur's large, sonorous and magnificently rich-toned voice was in its prime between the late 1890s and the World War I period. It was particularly suited to the performance of Italian operas. He was a versatile stylist with the unusual agility and his vocal range was astonishingly wide, allowing him to also sing baritone roles such as Tonio in Pagliacci and Count Almaviva in Le nozze de Figaro. Although chiefly a basso cantante, Didur could effectively deliver deep richness of basso profondo that made him one of the foremost interpreters of Boris Godunov. He was
