Otto Frank and Fritzi Markovits are married on 10 November 1953. For years Fritzi has helped Otto to answer the thousands of letters he receives from people who have read the diary. Some letter-writers become friends and come to visit.

Shortly before his death, Otto Frank says in an interview:

‘I am now nearly ninety and my powers are slowly waning. But the duty Anne left me continues to give me new strength – to fight for reconciliation and human rights throughout the world.’

Otto Frank dies on 19 August 1980. After his death Fritzi continues to answer letters.
