Mario Ancona (28 February 1860 – 23 February 1931), was a leading Italian baritone and master of bel canto singing. He appeared at some of the most important opera houses in Europe and America during what is commonly referred to as the "Golden Age of Opera".
Ancona was born into a middle-class Jewish family at Livorno, Tuscany, on 28 February 1860. After embarking on a business career he decided to study voice with a local singing teacher named Matteini in his native city of Livorno. Later, he took lessons from Giuseppe Cima in Milan.
Ancona is reputed to have made his debut as an amateur singer as far back as 1880; but according to The Concise Oxford Dictionary of Opera—from which many of the ensuing appearance dates, venues and career highlights are taken—his earliest known professional appearance in an opera did not occur until 1889, when he sang the role of Scindia in Massenet's Le roi de Lahore in Trieste. Not long afterwards, he appeared in another Massenet opera, Le Cid, at Italy's principal theatre—La Scala, Milan. His arrival at La Scala so soon after his debut reflects the excellence of the technical grounding that he must have received as an amateur performer.
On 21 May 1892, Ancona was asked to create the part of Silvio in the first performance of Leoncavallo's Pagliacci, which took place at Milan's Teatro Dal Verme with Arturo Toscanini conducting. The next year, he appeared in the first London performance of Pagliacci at the Royal Opera House, Covent Garden. On this occasion, however, he sang the role of Tonio. (Soprano Nellie Melba and tenor Fernando De Lucia were also in the high-quality cast.)
Ancona would appear regularly at Covent Garden until 1901, being held in high esteem by London audiences. He also sang as a guest artist in Cairo, Lisbon, Madrid, Warsaw, Moscow, St. Petersburg, Chicago, Boston and Buenos Aires.
