At the beginning of September 1938, a few weeks before our emigration, I came home. I was thus lucky enough to escape the November pogrom, which my teacher Albert Jonas later told me about. A gang of plainclothes thugs had entered the home at noon on November 10, beaten up the two male teachers Jonas and Samuel in front of the children, and then deported them to Dachau. Both were released in early January 1939, when Jonas was allowed to go to Sweden and Samuel to England.
