French painter, born in La Fère. He was associated with the Surrealist group and his paintings were preoccupied with anti-clerical themes. He encountered the group after exhibiting his painting Remembrance in the Salon des Artistes et Écrivains Révolutionnaires in Paris in 1930, which combined eroticism with anti-militarism. Here, a cleric in stockings and suspenders piously sprinkles holy water on dead German and French soldiers, while a contorted female nude in the sky drops medals. La Complainte (1933) equates the repressive power of church and state with images of a bloody guillotine, a skull with a bishop's mitre, and a weeping woman. In spite of the lurid and politically charged subject-matter of his painting, Trouille said that what interested him most was the intrinsic values of colour and material, whereas for André Breton what was most significant was the story. For this reason and because of his distaste for the internal squabbles of the group, he kept some distance from the Surrealists for much of the time.
