In 1965, his meeting with Alberto Giacometti is crucial, it confirms his desire to devote his life to sculpture and drawing. After some studies of mathematics in Clemenceau high school in Nantes, he moved to Nice and prepares his first studies on primary colours. Debarre met Max Ernst in the Alphonse Chave gallery in Vence returning to Paris. In 1973 he began a series of blue monochromes that will be exhibited in February 1974 in the museum of the Abbey Sainte Croix des Sables d’Olonne. There, he met Italian sculptor Antonino Virduzzo, who invited him to come and work in one of his workshops in Rome. The six years that followed helped him discover the Baroque art and its very many draperies. Back in Paris he began a long work on sculptures of black marble from Belgium, then of blue granite from Brazil, azul bahia. His work will then continue on a contemporary material, Altuglas. Black, blue and transparency will always be the basis of his work.
