Ernesto Halffter Escriche (16 January 1905 – 5 July 1989) was a Spanish composer and conductor. He was the brother of Rodolfo Halffter and part of the Grupo de los Ocho (English: Group of Eight), which formed a sub-set of the Generation of '27.
Ernesto Halffter was the third son of Prussian jeweller Ernest Halffter Hein and his wife Rosario Escriche Erradón. He was the younger brother of composer Rodolfo Halffter and the uncle of composer Cristóbal Halffter.
Halffter was born in Madrid and studied at the Colegio Alemán. He wrote his earliest composition at the age of six, and in 1922 his piano teacher Fernando Ember performed three pieces from Crepúsculos at the Ritz Hotel in Madrid. After meeting Manuel de Falla in 1923, Halffter sent Falla the score of his "Homenajes" trio for violin, cello and piano, which began a long relationship that included composition lessons from Falla.
Halffter's Sinfonietta is one of his earliest and best works; it shows the influence of Domenico Scarlatti. Later, he became more nationalistic with Rapsodia portuguesa for piano and orchestra, composed in 1938, during the Spanish Civil War. He wrote music for a dozen films. Perhaps the most noteworthy is Don Quixote de la Mancha, the 1947 film version of Miguel de Cervantes's classic novel. He also adapted and conducted the music for El amor brujo (1967), based on the ballet by Falla. It was directed by Francisco Rovira Beleta, was nominated for an Oscar and features guitarist Narciso Yepes.
