Adolphe Borchard (1882–1967) was a French pianist and composer who worked on a number of film scores during the 1930s and 1940s including large-budget films such as Ultimatum (1938). IMDb credits at least 19 films. He has several music students. The Vietnamese composer Nguyễn Văn Quỳ is one of them and studied through distance education between 1953 and 1954.
Borchard can be seen playing the piano in the first scene of Sacha Guitry's Confessions of a Cheat (1936) (French title: Le Roman d'un Tricheur), where he is introduced by the narrator.  He also appeared in the same director's Quadrille two years later.
