Renée Carpentier Wintz was born in Paris in 1913 and developed a reputation for her impressionistic landscapes and harbour scenes inspired by the coastal regions of Brittany, where shifting light, atmosphere, and maritime life became central themes in her work. She trained under the respected painter Lucien Simon at the École Nationale des Beaux-Arts in Paris, gaining a solid academic foundation that informed her confident handling of colour and composition throughout her career. She became a member of the Société des Artistes Français in 1934 and went on to exhibit regularly at important Parisian salons, including the Salon d'Automne and the Salon de la Marine, venues that played a significant role in establishing her professional standing within the French art world. In recognition of her artistic accomplishment, she was awarded the Prix Corot in 1952, a notable distinction that reflected both her technical ability and her contribution to the tradition of French landscape painting.

Renée was married to the painter Raymond Wintz, widely admired as a 'painter of light' and regarded as one of the foremost French artists working in maritime and coastal subjects during the mid-twentieth century. While his reputation was firmly established among critics and collectors, Carpentier Wintz maintained her own distinct artistic voice, and her paintings are today held in private and public collections throughout France and across Europe.
