Quentin Reynolds died on March 17, 1965, at the not-very-old age of sixty-two. Putzi Hanfstaengl, whose sheer size had seemed to make him invulnerable, died on November 6, 1975, in Munich. He was eighty-eight. Sigrid Schultz, the Dragon from Chicago, died on May 14, 1980, at eighty-seven. And Max Delbrück, presumably with a full head of hair, passed away in March 1981, his exuberance quenched at last. He was seventy-four.
