From JD Salinger’s Wikipedia Page:
During the campaign from Normandy into Germany, Salinger arranged to meet with Ernest Hemingway, a writer who had influenced him and was working as a war correspondent in Paris.[33] Salinger was impressed with Hemingway’s friendliness and modesty, finding him more “soft” than his gruff public persona.[34] Hemingway was impressed by Salinger’s writing, and remarked: “Jesus, he has a helluva talent.”[3] The two writers began corresponding; Salinger wrote Hemingway in July 1946 that their talks were among his few positive memories of the war.[34] Salinger added that he was working on a play about Holden Caulfield, the protagonist of his story “Slight Rebellion off Madison”, and hoped to play the part himself.[34]
