Your article brought many thoughts to mind, one of them being the falling out between Hemingway and John Dos Passos at this time. Here is a Paris Review piece that ends with the book about it, which somewhat tarnishes Hemingway’s reputation. Just as no one can take it away from Lindbergh that he accomplished a major feat in 1927, no one can take it away what Hemingway achieved and his influence on modern lit.
For Whom the Bell Tolls is still my favorite Hemingway novel, which I read for the third or fourth time this summer. The film is a fail, but that is how Hollywood can be sometimes.
