Ettore Panizza (born Héctor Panizza; 12 August 1875 – 27 November 1967) was an Argentinian conductor and composer, one of the leading conductors of the early 20th century. Panizza possessed technical mastery and was popular and influential during his time, widely admired by Richard Strauss and Giacomo Puccini, among others.
Panizza was born in Buenos Aires, of Italian parents. His birth name was Héctor Panizza but throughout his career he was known as Ettore. Panizza studied first with his father, who was a cellist at the old Teatro Colón, and later in Milan. He made his debut as assistant conductor at the Rome Opera in 1897.
He was closely associated with La Scala in Milan (where he conducted, along with Toscanini, titles like Wagner's Ring in 1926), the Royal Opera House in London, the Metropolitan Opera in New York City- where he succeeded Tullio Serafin as principal conductor of Italian repertoire, working for eight seasons with names like Rosa Ponselle and Enrico Caruso - and mainly at the Teatro Colón in Buenos Aires where his opera Aurora was premiered during the inaugural season.
He conducted Puccini's Turandot with the ending by Franco Alfano after the world premiere at La Scala on 25 April 1926 conducted by Arturo Toscanini, who stopped at the point where Puccini had ceased writing before his death.
