Anne Frank wrote under a pseudonym

There's more about Anne Frank that you don't know than you think. Anne Frank’s full name was Annelies Marie Frank. Anne Frank used pseudonyms for the persons she wrote about in her diary as she prepared it for ultimate publication. Do you know what pseudonym Anne picked for herself, even if you are familiar with the pseudonyms of Albert Dussel (the real Freidrich Pfeffer) and Petronella van Daan (the real Auguste van Pels) because these pseudonyms appear in most published editions of the diary?

Otto Frank made the decision to use his family's true identities instead of the pseudonyms Anne had established for the other four persons sheltering in the Annex when it came time to publish the diary after the war. Because of this, we are more familiar with Anne Frank by her given name than her initial alias, Anne Aulis, or her given name, Anne Robin (the name Anne later chose for herself). For Margot Frank, Otto Frank, and Edith Frank, Anne adopted the aliases Betty Robin, Frederik Robin, and Nora Robin, respectively.
