One of Amsterdam's main tourist attractions, it received an average of 1.2 million visitors between 2011 and 2020. In 1963, Otto Frank and his second wife, Elfriede Geiringer-Markovits, set up the Anne Frank Fonds as a charitable foundation, based in Basel, Switzerland. Upon his death, Otto willed the diary's copyright to the Fonds, on the provision that the first 80,000 Swiss francs in income each year was to be distributed to his heirs. The Anne Frank Fonds represents the Frank family and administers the rights, inter alia, to the writings of Anne and Otto Frank and to the letters of the Frank family.

The first writer selected was the Algerian novelist and poet El-Mahdi Acherchour. Anne Frank is included as one of the topics in the Canon of the Netherlands, which was
