Yves Kugelmann, a trustee with the Anne Frank Fonds, the nonprofit established by Otto Frank in 1963, told the failing New York Times that legal experts consulted by the foundation over the previous six years have concluded that the editing, merging and trimming of entries by Anne’s father “created a new work”.
“He merged them, he cut them and he changed them. So he created a new book,” Kugelmann told Canada’s Globe and Mail.
“It means that they have lied for years about the fact that it was written by Anne Frank,” French intellectual property attorney Agnès Tricoire told the failing New York Times.
The revelation has also increased the already existing tensions between the Anne Frank Fonds and the separate organization that manages the Anne Frank House in Amsterdam.
The failing New York Times reports the decision by the Anne Frank Fonds could be tested in the courts.
