Son of Paul Mascart, born in Duclair on the banks of the Seine (department of Seine-Maritime). In contact with his father, Roland was introduced at a very young age to drawing and painting Norman nature. In 1923, he entered the School of Fine Arts in Rouen where he received an academic training. He exhibited for the first time in this city in 1925. Other exhibitions followed one another with works whose style aroused the enthusiasm of regional critics, until the family left for Oceania in 1929. The stay in New Caledonia gave him the opportunity to express his talents as a colorist through numerous pastels or oils and to show his interest in the Kanak world. This period is undoubtedly the most fruitful of his career. Back in mainland France with his parents in 1934, he soon set up his own studio in Paris and participated in numerous exhibitions giving him the opportunity to show his rich Caledonian production. After the war, he traveled regularly to Vendée, Dordogne and the south of France. But Roland Mascart still dreams of returning to New Caledonia one day, and he embarks in 1970 with the project of an exhibition in Nouméa of works from the 1930s as well as paintings by his father. A few years later, in 1974-1975, he made a final six-month trip to New Caledonia, an opportunity to once again satisfy his passion for Oceania and to produce numerous works on Grande Terre and the Loyalty Islands.
