content: Dubious authorship too.  Authorship In 2015, the Anne Frank Fonds made an announcement, as reported in The New York Times, that the 1947 edition of the diary was co-authored by Otto Frank. According to Yves Kugelmann, a member of the board of the foundation, their expert advice was that Otto had created a new work by editing, merging, and trimming entries from the diary and notebooks and reshaping them into a "kind of collage", which had created a new copyright. Agnès Tricoire, a lawyer specializing in intellectual property rights, responded by warning the foundation to "think very carefully about the consequences". She added "If you follow their arguments, it means that they have lied for years about the fact that it was only written by Anne Frank." https://en.wikipedia.org/wiki/The_Diary_of_a_Young_Girl#Authorship
