In 1936, the Olympic Games were held in Berlin. Shortly after that we all went back to school and suddenly I noticed that none of my mates would have anything to do with me. I felt very odd and I spoke to one of them. And to give him his due, he was very honest. I said, ‘Fritz, what’s going on? We’re all good friends here but nobody speaks to me’. ‘Yes’, he said, ‘I’ll be very honest with you. My father said I mustn’t play with Jewish kids anymore’. And that was traumatic. Suddenly I was ostracised. Suddenly all my friends- I saw them, you know, as close as you are to me, for instance, but they wouldn’t speak to me.
