François Gall studied in Rome at the Accademia de Belle Arti while performing manual jobs. In 1930 he obtained a grant from the Hungarian government and settled in Paris in 1936 where he trained with Devambez at the École Nationale des Beaux-Arts.
He was influenced by the French Impressionists and specialised in painting young, pretty Parisian girls, whom he observed in every situation of their busy day, from their private life, across typical Parisian scenes, in the bustle of the cafes or in the world of theatre and dance, as far as at the beaches and at the fashionable horse races.
Alongside his painting, François Gall had important administrative roles in the arts. He was Vice-President of the national retirement fund for the arts (IRCEC), administrator of the Society of Independent Artists (Vice-President from 1976 to 1981), administrator of the Taylor Foundation and administrator of the ADAGP. Gal became Officier des Arts et des Lettres and was awarded the gold medal for distinguished services by the French government.
Since 1936 Gall featured in numerous collective exhibitions in Paris including: Salons des Artistes Français (winning awards and medals); Salon des Indépendants; Salon d'Automne, Salon des Peintres Témoins de leur Temps; Salon du Dessin; Salon de Peinture à l'eau; Salon Comparaisons. He also participated in many exhibitions outside Paris and abroad. Solo exhibitions include: Durand-Ruel gallery, Paris (1949); Marlborough Gallery, London; Touraine Art Gallery, New York (1953). François Gall won the Francis Smith prize in 1963.
