A first instrument built by Cavaillé-Coll in 1877 had 45 stops, but the instrument did not remain in the church because it was requisitioned to be installed in the enclosure of the newly built Trocadéro Palace in 1878 . The parish priest of Notre-Dame d’Auteuil, Pierre Lamazou then ordered another organ from Cavaillé- Coll, who completed it in 1885 (opus 105). It had 32 stops spread over two 54-note keyboards and a 30- note Pedal board. Inaugurated by Charles-Marie Widor (Saint-Sulpice) and Henri Dallier in 1885, the two-key organ was restored in 1912 by Mutin. An expressive Positive by the organ-buider Gloton- Debierre is added in 1937-1938, while fully respecting the harmony of the three Cavaillé-Coll sound planes (Grand-Orgue, Récit, Pédale). On this occasion the number of stops increased to 53 and the organ electrifies the transmissions (Debierre electro-pneumatic system) and set up a new console*. For this restoration-extension, the opinion of two renowned musicians: Louis Vierne and Albert Alain was requested. In 1962-63 the instrument was dusted off by Barbéris and Picaud (Maison Debierre) and a lifting took place in 1983 under the leadership of Henri Veysseyre carried out by Jacques Barbéris. Finally in 2015-2018 the organ was restored by the organ maker Denis Lacorre under the contracting authority of the city of Paris. Technically, the grand-organ keyboard is reconfigured as in 1885 by the removal of the Beuchet Cymbal, the re-establishment of the Plein- Jeu Cavaillé (resulting from 16 then 32 ’), and re- setting of the double pressures. In Positif, the flute mutations desired by Gloton (former worker of the Cavaillé-Coll firm) are installed. It was decided to keep the Gloton Plein-Jeux at the Swell due to their good workmanship, but adjustments were made by adding conventional Plein-Jeux to the three keyboards (resulting 8 ’on the Grand-Orgue). An Unda Maris game is added to the GO keyboard. The wind supply and the windchests have also been revised. The transmission of notes and stops is digital, while the Gloton console has been preserved with additions of sostenutos and pedal cut-off. All in all, it is a magnificent instrument allowing the performance of the symphonic and romantic repertoire, as well as that of the 1930s: Messiaen, Fleury, Dupré, Duruflé for example. * Gloton shifted the pedal chests to the lateral galleries, added a 32’ Soubasse and placed both Positif swellboxes into the space freed in the main case by the displacement of the Pedal division. On the GO, a Fourniture IV, Cymbale IV and a Flûte douce 4’ was added. On the Récit, a Nasard 2 2/3 and a Fourniture IV was added. On the pedal, also a Fourniture IV was added and the 32-16-8 Flûtes foundations were duplicated.

The Notre-Dame-d'Auteuil church was built in 1877- 1892 in a Romanesque-Byzantine style by the architect Joseph-Émile Vaudremer.
