Born at Nogent-sur-Marne August 20, 1911. His family was originally from Brittany where he spent his childhood. Studied publicity in Paris, where he began to paint without a teacher to guide him. He took a trip to Morocco and one to Spain 1932 to 1937, then returned to Brittany in 1938. At that time he came under the influence of Sérusier and is afterwards fascinated by Braque. From his experience with these two masters he catches a glimpse of the possibilities of abstraction, a tendency which strengthens his meeting with Domela. Jeanne Bucher buys his first non-figurative paintings. In 1946 he receives the encouragement of Wilhelm Uhde. Several brief stays in Denmark, in Germany. After the Liberation he exhibited at the Salon d'Automne of 1944, classified as an abstract painter. In 1945 and 1946 he exhibited at the Salon des Surindépendants, and since 1945 he has been exhibiting at the Salon de Mai. Since 1947 he has been exhibiting regularly at the Galerie Denise René. Deyrolle composes free architectual paintings in tones of shaded tints; his work is dominated by a scientific and patient analysis of values.
