Answer
Debussy and Ravel, two prominent French composers of the late 19th and early 20th centuries, profoundly influenced Henri Dutilleux's musical style. Dutilleux admired their innovative use of harmony, orchestration, and structure, which he incorporated into his own compositions. Their influence can be heard in Dutilleux's rich and colorful orchestral works, as well as in his exploration of new sonorities and textures.
