Ten years ago, Richard Rubin set out to interview the last of the doughboys, several dozen, aged 101 to 113. They shared with him, at the last possible moment (they are all gone now), the story of America's Great War and of the generation that raised the 'greatest generation'. They were nineteenth-century men and women living in the twenty-first century: self-reliant, humble, and stoic; never complaining, still marveling at the immensity of the war they helped win.
