My great-uncle, Jacques Graubart, came to town last weekend. Jacques, a fit and vigorous 79, has always been the superhero against whom I\’ve measured my life. Jacques entered the Resistance when he was 19 and rowed hundreds of Jews to safety from occupied France into Switzerland. He was caught frequently by the French and escaped every time but the last time. Incarcerated by the Nazis in a series of concentration camps, Jacques survived a death march of prisoners that began with 1,400 and ended with himself and only three others alive.
