Bernard Peiffer was born on October 23, 1922 in Epinal, in the Vosges district of northeastern France. Bernard’s father, formerly an army man, was a violinist and was devoted to chamber music. An uncle, Georges Peiffer, was a composer and church organist. Bernard began his music study at the age of nine; he studied piano and harmony privately with Pierre Maire (a student of Nadia Boulanger) and dazzled older students with his ability to play back extended sections of classical pieces by ear. He continued his studies through his teens at Ecole Normale de Paris, the Marseille Conservatory, and the Paris Conservatory, where he won the coveted and revered First Prize in Piano.
Attracted by the freedom and improvisational basis of jazz and influenced by the pianistic styles of Fats Waller and Art Tatum, Bernard made his professional debut in 1943, at the age of 20, with alto saxophonist Andre Ekyan
