How many literary legends does it take to prop up a Nazi-era Parisian hotel? Ernest Hemingway, then 45, helped boost the spirits of young J.D. Salinger — these are two of my favorite writers — during the war. This feature, and The Thread podcast, offer a wonderful depiction of the relationship between these great American authors. I had never heard this story before, but it’s no surprise that Hemingway and Salinger became fast friends over champagne in the midst of such devastation. I’d highly recommend reading For Whom the Bell Tolls and The Catcher in the Rye.
