Antoine Ponchin was born in Marseilles, France. His artistic training was in Paris where he studied under Jules Gagliardini and Fernand Humbert. The artist Jean Baptiste Olive also influenced Ponchin.
His works were recognized in 1904 when he exhibited at the Salon des Artistes in Paris, again in 1906 and again in 1910. Ponchin later received the Legion d’Honneur for his accomplishments in painting landscapes and marine works.
Several museums in France feature Ponchin’s works. In 1999, the Huntsville Museum in Alabama staged a retrospective featuring Ponchin’s paintings alongside those of his father and son (also artists).
