prepared by a committee headed by Frits van Oostrom and presented to the Minister of Education, Culture and Science, Maria van der Hoeven, in 2006. The Canon is a list of fifty topics that aims to provide a chronological summary of Dutch history to be taught in primary schools and the first two years of secondary school in the Netherlands. A revised version, which still includes her as one of the topics, was presented to the Dutch government on 3 October 2007, and approved in 2020. In June 2007, "Buddy" Elias donated some 25,000 family documents to the Anne Frank House. Among the artefacts are Frank family photographs taken in Germany and the Netherlands and the letter Otto Frank sent his mother in 1945, informing her that his wife and daughters had perished in Nazi concentration camps. In November 2007, the Anne Frank tree—by then infected with a fungal disease affecting the tree trunk—was scheduled to be cut down to prevent it from falling on the surrounding buildings. Dutch economist Arnold Heertje said about the tree: "This is not just any tree. The Anne Frank tree is bound up with the persecution of the Jews." The Tree Foundation, a group of tree conservationists, started a civil case to stop the felling of the horse chestnut, which received international media attention. A Dutch court ordered city officials and conservationists to explore alternatives and come to a solution. The parties built a steel construction that was expected to prolong the life of the tree up to 15 years. However, it was only three years later, on 23 August 2010, that gale-force winds blew down the tree. Eleven saplings from the tree were distributed to museums, schools, parks and Holocaust remembrance centres through a project led by the Anne Frank Center USA. The first sapling was planted in April 2013 at The Children's Museum of Indianapolis. Saplings were also sent to a school in Little Rock, Arkansas, the scene of a desegregation battle; Liberty Park (Manhattan), which honours victims of the September 11 attacks; and other sites in the United States. Another horse chestnut tree honouring Frank was planted in 2010 at Kelly Ingram Park in Birmingham, Alabama. Over the years, several films about Anne Frank appeared. Her life and writings have inspired a diverse group of artists and social commentators to make reference to her in literature, popular music, television, and other
