Joseph Simon provides a useful summary of the life of Emile Blanchet, who traded at 32 rue Bonaparte until moving to 20 rue St-Benoit by 1888: 'He married Marie or Félicité Cazaux in 1887, when he was described as of 39 rue Bonaparte, son of Jean Philibert Blanchet... In 1889 he was offering ‘couleurs extra-fines pour l’huile, l’aquarelle, etc, toiles à tableaux, chevalets, bottes d’artistes, brosses et pinceaux, huile grasse et bleu de lumière’ (Annuaire-Almanach du commerce…Didot-Bottin, 1889). He advertised in the 1896 Salon catalogue as ‘maison de la palette d’or’, founded in 1800, offering ‘Toiles a Tableaux de toutes largeurs, couleur extra fines’, with a factory and workshops at Vaugirard (Catalogue illustré du Salon, 1896)'.
He sold artist's supplies including canvases and frames, and restored paintings. Whistler appears to have patronised Benoit in Paris in the early 1890s.
