 His father, Ernst Klug, had grown up far to the south in Vogtland where he had turned down the opportunity to train as a teacher, preferring an apprenticeship as a butcher because, as he put it, "a butcher can always get enough to eat".As a young man, while travelling, Ernst Klug met Emma Lucht in Hamburg.Her family came from nearby Albersdorf, and after a protracted courtship the couple married and set up their home in the Hamburg quarter of Eimsbüttel.
