Thierry Escaich is a composer, organist, improvising keyboardist, and concert performer in whose appearances the various aspects of his work intersect. In 1992, he joined the faculty of the Conservatoire de Paris and remained there as of the early 2020s. Escaich was appointed co-organist titulaire of the St.-Étienne-du-Mont church in Paris in 1996, succeeding Maurice Duruflé; he also remains in that position. With well over 100 compositions to his credit, Escaich is perhaps best known as a composer. He has written for organ and piano, but his works are in a large variety of media, including orchestral. Escaich's works have been performed by the Philadelphia Orchestra, the Berlin Konzerthaus Orchestra, and pianist Christoph Eschenbach, among many other individuals and ensembles.
