Léo Chauliac, real name Léon Chauliac (6 February 1913 – 27 October 1977) was a French jazz pianist, composer and conductor.
A jazz pianist in the 1930s, Léo Chauliac was the accompanist of Charles Trenet from 1941 to 1943, a singer for whom he composed many popular songs.
He rubbed shoulders and played with the greatest musicians of the time: Hubert Rostaing, Aimé Barelli, Alix Combelle and Henri Crolla.
For a while, as conductor of the orchestra of the famous restaurant Maxim's, he will be the companion for some records by André Claveau and Jacqueline Danno.
But it was above all with Jean-Claude Pascal that he wove a long musical career in the 1960s, orchestrating among other things Nous les amoureux, winner of the 1961 Eurovision Song Contest.
