Who introduced major American authors to French readers in the period between the World Wars? Who worked to popularize French literature in the US? Among the artisans of this transatlantic trade, two little-known figures stand out: William and Jenny Bradley, who founded the first literary agency in France, placing themselves at the service of Colette, Gide, Sartre and Camus, but also Faulkner, Hemingway, and Baldwin. Drawing on previously unavailable archives, this work invites readers to discover the never-before-told story of a French-American couple in the 1920 after the Great War.
