Eugenio Cavallini (16 June 1806 — 11 April 1881) was an Italian conductor, composer, violinist, and violist.
 In 1833 he became first violinist of the orchestra at La Scala, a post he held through 1855.
 He also served as a conductor at La Scala, notably leading the world premieres of Gaetano Donizetti's "Lucrezia Borgia" (1833), Donizetti's "Gemma di Vergy" (1834), Donizetti's "Maria Stuarda" (1835), Saverio Mercadante's "Il giuramento" (1837), Mercadante's "Il bravo" (1839), Giuseppe Verdi's "Oberto" (1839), Verdi's "Un giorno di regno" (1840), Donizetti's "Maria Padilla" (1841), Verdi's "Nabucco" (1842), Verdi's "I Lombardi alla prima crociata" (1843), Verdi's "Giovanna d'Arco" (1845), Federico Ricci's "Estella di Murcia" (1846), and Domenico Ronzani's "Salvator Rosa" (1854).
Sara Mingardo (born 2 March 1961) is an Italian classical contralto who has had an active international career in concerts and operas since the 1980s.
 Her complete recording of Anna in Hector Berlioz's "Les Troyens" won a Gramophone Award and both the Grammy Award for Best Opera Recording and the Grammy Award for Best Classical Album in 2002.
 Some of the other roles she has performed on stage or on disc include Andronico in "Tamerlano", Mistress Quickly in "Falstaff", Rosina in "The Barber of Seville", and the title roles in "Carmen", "Giulio Cesare", "Riccardo Primo", and "Rinaldo".
 She has also recorded several Vivaldi cantatas, Bach cantatas, and such concert works as Mozart's "Requiem", Rossini's "Stabat Mater", and Vivaldi's "Gloria" among others.
Iva Pacetti (13 December 1898, Prato - 19 January 1981, Milan) was an Italian operatic soprano who had an active international career from 1920-1947.
 Trained in Florence and Milan, she made her professional opera debut in her native city at the age of 21 as the title heroine in Giuseppe Verdi's "Aida" at the Teatro Metastasio.
 She reprised the role the following year at Loew's Lexington Theatre in New York City.
 In 1922 she had a triumphant success at the Teatro Carlo Felice as Elena in Arrigo Boito's "Mefistofele".
 Engagements with other important opera houses soon followed, including La Scala, the Teatro Costanzi, the Teatro di San Carlo, the Opéra de Monte-Carlo, the Chicago Civic Opera, the Teatro Colón, the Teatro Municipal in Rio de Janeiro, and the Theatro Municipal in São Paulo.
 From 1930-1933 she was committed to the Royal Opera House in London, portraying such roles as Desdemona in "Otello", Leonora in "La forza del destino", and the title role in "Tosca".
 The latter years of her career were spent performing primarily at La Scala where she was a frequent partner of Beniamino Gigli.
 She retired from the stage in 1947, after which she was active as a voice teacher in Milan.
Enzo Muccetti (born June 29, 1912 in Corfinio; died March 24, 1977 in Parma) was a great Italian classical bassoonist and pedagogue.
 He studied at the Giuseppe Verdi Conservatory in Turin, originally with the intention of learning the cello but shifting to the bassoon which was more suited to his small hands.
 Although he started out with the Buffet system, he switched to the German system.
 His work improving the mechanics of the bassoon was readily accepted by Heckel, which eventually designed and dedicated a special model of bassoon to him, "Model 41, Special E.M." Heckel built bassoons with three different styles of bells, one of which, the "Muccetti" bell (also known as the Italian bell), was named after him.
 He served as principal bassoonist at La Scala from 1947 to 1971.
 After conducting a La Scala concert, Paul Hindemith wrote in his programme "if all bassoonists were so marvelous, life, and especially writing for the bassoon, would be more of a joy than it usually is."
 Similarly, Herbert von Karajan wrote after a series of concerts at La Scala, "I'm pleased to have found a bassoonist of such stature that in almost all European orchestras there is no one to be compared with you."
 Muccetti was a professor at the Parma Conservatory, where his students included Evando Dall'Oca (his eventual successor at La Scala), Romano Santi, Michael Chapman and Wendy Philips.
Teresa Ruggeri (sometimes spelled Ruggieri) was an Italian operatic soprano who had an active career from the 1820s through the 1840s.
 In 1827 she portrayed the role of Zarele in the world premiere of Giovanni Pacini's "Gli arabi nelle Gallie" at La Scala in Milan.
 She performed in several more world premieres at that house, including Francisca in Gaetano Donizetti's "Maria Padilla" (1841), Anna in Giuseppe Verdi's "Nabucco" (1842), and Viclinda in Verdi's "I Lombardi alla prima crociata" (1843).
 Other roles she performed at La Scala included Baroness Aspasia in Gioachino Rossini's "La pietra del paragone" (1829), Giannetta in Donizetti's "L'elisir d'amore" (1835), Alisa in Donizetti's "Lucia di Lammermoor" (1839), The Marquise of Birkenfeld in "La fille du régiment" (1840), and Giovanna in Verdi's "Ernani" (1844) among others.
Falstaff (] ) is an opera in three acts by the Italian composer Giuseppe Verdi (18131901).
 The libretto was adapted by Arrigo Boito from Shakespeare's "The Merry Wives of Windsor" and scenes from "Henry IV", parts "1" and "2".
 The work premiered on 9 February 1893 at La Scala, Milan.
Nabucco (] ; short for Nabucodonosor ] ~] , English Nebuchadnezzar) is an Italian-language opera in four acts composed in 1841 by Giuseppe Verdi to an Italian libretto by Temistocle Solera.
 The libretto is based on biblical books of Jeremiah and Daniel and the 1836 play by Auguste Anicet-Bourgeois and Francis Cornue, although Antonio Cortese's ballet adaptation of the play (with its necessary simplifications), given at La Scala in 1836, was a more important source for Solera than the play itself.
 Under its original name of "Nabucodonosor", the opera was first performed at La Scala in Milan on 9 March 1842.
Francesco Dominici (1885–1968) was an Italian operatic tenor particularly admired for his acting in comedic roles.
 He made his professional opera debut as Fernando in Donizetti's "La favorite" at the Teatro Donizetti in Bergamo in 1914.
 He created the role of Prunier in the original 1917 production of Puccini's "La rondine" at the Grand Théâtre de Monte Carlo, a role which he performed at many other opera houses including the Teatro Comunale di Bologna.
 Over the next several years he played mostly leading roles at the Teatro Costanzi in Rome including Rodolfo in Puccini's "La Bohème", Fenton in Verdi's "Falstaff", and the Ernesto in Donizetti's "Don Pasquale".
 In the early 1920s he joined the roster at La Scala where he began playing more buffo roles than leading roles.
 In 1921, he sang the role of doctor Cajus in Verdi's Falstaff at La Scala and in 1922 was Filipeto in the company's first production of Ermanno Wolf-Ferrari's "I quattro rusteghi".
 In 1926 he created the role of Emperor Altoum in the original production of Puccini's "Turandot" at La Scala.
 In 1929 he went on tour with La Scala to Germany.
 Other roles that Dominici performed at La Scala include David in Wagner's "Die Meistersinger von Nürnberg", Monostatos in Mozart's "The Magic Flute", and the Neipperg in Umberto Giordano's "Madame Sans-Gêne".
 In 1931 he moved to Cuba, where he taught music for many years.
 Dominici died in Havana in 1968.

 He will also appear as the title role in the Metropolitan Opera's new production of "Otello", which will open the Met's 2015-2016 season.
 The production is notable within American opera circles due to the Met's decision to abandon their tradition of blackface for the role of Otello.
 Other future performances include "Norma" at the Bavarian State Opera, "Otello" at Barcelona's Gran Teatre del Liceu and Zürich's Opernhaus, and "Pagliacci" at the Royal Opera House in London.
