Son of the painter Antoine Ponchin who passed on to him the taste for drawing and encouraged him in his vocation, allowing him to follow a solid academic training with Cormon and Dawant at the Ecole des Beaux Arts. He exhibited at the Salon des Artistes Français from 1920 and won several awards there: TH prize. Ralli (1920) and Henri Zuber (1929). After initial experiences in Corsica and then in Algeria, he ventured into Asia, following his father who had just won the Indochina Prize and was entrusted with a major official commission from the state. The young painter held a teaching position at the French high school in Hanoi, until his return to France in 1931. After two years in Reims, he returned to settle his family in the South, where he seemed particularly attached to the representation of landscapes. He devoted most of his work to translating the effects of light in Mediterranean panoramas onto canvas. He was a drawing teacher at the Thiers high school in Marseille at the end of his career. The Museum of Fine Arts in Marseille has preserved his "Annamite Women".
