‘Dear Kitty' made her first appearance in Anne's diary on 22 September 1942. By then, Anne had been in hiding in the Secret Annex for two months. Although life in hiding was not easy, the people there slowly developed new routines. For Anne, writing in her diary became an important part of her routine.
Kitty is Anne’s favourite imaginary friend
Anne wrote that she wanted 'to correspond with someone' and invented several fictional characters (Kitty, Pop, Phien, Conny, Lou, Marjan, Jettje, and Emmy) to do so. In Anne's fantasy, these characters formed a circle of friends. She started with Jettje and Emmy, and then the name Kitty appeared. Anne addressed her as ‘Dear Kitty’, ‘My darling Kitty’, and ‘Dearest Kitty’.
Anne’s imagination was very lifelike. She had preferences for some of the characters and Kitty rose to first place straight away: ‘Dear Kitty...I like writing to you most, you know that don’t you, and I hope the feeling is mutual. Jettje and Emmy received the occasional letter and Anne wrote: ‘Jacqueline isn’t really part of the group’.
‘Jacqueline’ was Jacqueline van Maarsen, Anne's friend at the Jewish Lyceum. She wrote her two farewell letters, after which no more letters were addressed to Jacqueline. It is unclear why Jacqueline wasn’t ‘part of the group’.
