Luis de Pablo Costales (28 January 1930 – 10 October 2021) 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.

[3] For a short time after graduating in 1952, he was employed as legal advisor to Iberia Airlines, but soon resigned this post in order to pursue a career in music.

He was particularly concerned with promoting appreciation in Spain of the Second Viennese School, publishing translations of Hans Heinz Stuckenschmidt's biography of Arnold Schoenberg in 1961, and texts by Anton Webern in 1963.

[1] De Pablo composed film scores, collaborating with directors such as Víctor Erice (The Spirit of the Beehive) and Carlos Saura (The Hunt).
