When Did Luis de Pablo Die?

Luis de Pablo Costales was a Spanish composer belonging to the generation that Cristóbal Halffter named the Generación del 51. Mostly self-taught as a composer and influenced by Maurice Ohana and Max Deutsch, he co-founded ensembles for contemporary music, and organised concert series for it in Madrid. He published translations of notable texts about composers of the Second Viennese School, such as Hans Heinz Stuckenschmidt's biography of Arnold Schoenberg and the publications of Anton Webern.
