His name was tsvi nussbaum-his parents and entire family were killed,and he survived somehow...later floated all over the world like the flotsam that war throws up,like millions of other jewish orphans-and finally ended up in new york's ghettos,went to school,excelled at science,and became a doctor.he was located by the press in 1980 and identified as "the boy"...he broke down at the interview,weeping inconsolably."i feel a tremendous guilt-why did i survive?"
