Léon-Étienne Duval was born in Chênex, Haute-Savoie, and attended the seminary in Annecy before going to Rome, where he studied alongside Marcel Lefebvre at the Pontifical French Seminary. Ordained to the priesthood on 18 December 1926, he then did pastoral work in Annecy until 1942, whilst teaching at the seminary and serving as Director of Works. During World War II, Duval supported the French Resistance and was wary of the Vichy regime. He was an honorary canon and vicar general of Algiers from 1942 to 1946.

On 3 November 1946 Duval was appointed Bishop of Constantine by Pope Pius XII. He received his episcopal consecration on 11 February 1947 from Bishop Auguste Cesbron, with Bishops Raoul Harscouêt and Léon Terrier serving as co-consecrators. Duval was later named Archbishop of Algiers on 3 February 1954.
