His father, a Strasbourg dignitary, refuses to follow an artistic career; encouraging him more in pastry than in painting. Luc Hueber practices as a pastry chef and engages in the foreign legion. He trained as a painter of stained glass with Auguste Cammissar (1873-1963) and continued his apprenticeship at the School of Decorative Arts in Strasbourg. In 1924, he acquired the House of the Gentiles at La Petite-Pierre (today a place of exhibition) and enjoyed painting the surrounding nature.
