Jack, Papa's oldest boy, has been dead for several years now. Although Papa hung around a few wars, Jack was the closest Hemingway to a real hero: Behind the lines in France in WWII with the OSS (he jumped with a fly rod!), one of the very early Green Berets after the war. Wrote an interesting memoir; also some hunting and fishing stories for Field and Stream. But as he admitted in his memoir, his fate was to be the son of a famous father, and the father of famous daughters (Mariel and Margot).
