His membership in the Group of Thirteen places him at the heart of a significant regional artistic movement of the early 20th century. This collective of Provençal artists, although short-lived with only two exhibitions between 1912 and 1913, marked local artistic history through its commitment to promoting regional art.
The first exhibition on December 21, 1912, met with an enthusiastic reception, confirming the relevance of this collective initiative. The success of this event testified to the public's expectation of art rooted in Provençal traditions and landscapes. The second exhibition on December 18, 1913, which would be the group's last, brought to a close this promising collective experience, interrupted by the upheavals of the Great War.
His individual recognition continued into the 1920s. The 1929 exhibition at the Salon des Artistes Français revealed his mastery of watercolor through works evocative of Provençal heritage and landscapes. "La Chapelle romane", "Chemin en Provence", "Route avec cyprès" and "Avignon le matin" illustrate his attachment to his native region and his ability to restore its poetic essence.
His active participation in the Société nationale des beaux-arts and the Salon des indépendants confirms his recognition in the official Parisian artistic circuits. This dual affiliation - local through his subjects and national through his exhibitions - characterizes a balanced career between regional roots and artistic ambition.
His creative longevity, spanning nearly seventy years, demonstrates a constant fidelity to his aesthetic vision. Bergier embodies the artist-witness of his region, perpetuating with his brush the beauty of the Provençal landscapes and the richness of Avignon's heritage through the changes of the 20th century.
