Most parents don’t know really their children.

To build up a future, you have to know the past.

We all had lots of stories of our sad experiences - they mourned the death of my wife with me - but we were hopeful that the children would return.

I think it is not only important that people go to the Anne Frank House to see the secret annex, but also that they are helped to realise that people are also persecuted today because of their race, religion or political convictions.

I hope Anne's book will have an effect on the rest of your life so that insofar as it is possible in your own circumstances, you will work for unity and peace.

One day in Auschwitz I became so dispirited that I couldn't carry on. They had given me a beating, which wasn't exactly a pleasant experience. It was on a Sunday, and I said: 'I can't get up'. Then my comrades said: 'That's impossible, you have to get up, otherwise you're lost'. They went to a Dutch doctor, who worked with the German doctor. He came to me in the barracks and said: 'Get up and come to the hospital barracks early tomorrow morning. I'll talk to the German doctor and make sure you are admitted'. Because of that I survived.
