Born in Athens after studying at the Conservatory, Nicola Zaccaria (1923-2007), made his début in 1949 as Raimondo in Lucia di Lammermoor. Four years later he appeared at La Scala, Milan, as Sparafucile in Rigoletto. Throughout the 1950s and 1960s he appeared in many leading Italian opera seasons: at Florence, Verona and Rome in the typical Italian repertory. In 1956 he was a guest at the Vienna Staatsoper and at the festival in Salzburg; and in 1957 at Covent Garden with Callas’s Norma he was Oroveso and in 1959 Creon with her Medea. His career was wide and embraced Cologne, Brussels, Ghent, Moscow, Mexico City, Rio de Janeiro, Monte Carlo, Berlin and Dallas, which he returned to often until the 1980s, as well as festivals at Aix-en- Provence, Edinburgh, Orange and Athens. He sang rôles such as Zaccaria in Nabucco, Silva in Ernani, Rodolfo in Sonnambula and Sarastro in Zauberflöte. For EMI he appears with Callas in recordings of Aida, Un ballo in maschera, Il Trovatore, La Bohème, Il barbiere di Siviglia, La Sonnambula and Norma.
