Anne Frank’s 97th Birthday

None

June 12, 2026 — Today we commemorate Anne Frank’s birthday. Anne Frank was born in Frankfurt am Main on 12 June 1929, 97 years ago today. She was the younger sister of Margot Frank, who was born on 16 February 1926, 100 years ago this year. Despite their very different personalities, the sisters shared a close bond.

Anne was extroverted, while Margot was introverted. In her diary, Anne often complained about the scoldings she received from her mother and from the other adults in their hiding place. Margot, by contrast, was the model child. On 27 September 1942, Anne wrote: “Some people seem to take particular pleasure in not only raising their own children but also those of their acquaintances; Van Pels is one of them. There is nothing to be taught to Margot—she is goodness, kindness and intelligence personified. But I more than make up for her share of mischief.”

Anne’s and Margot’s diaries

Anne confided her deepest feelings to her diary. It served both as an emotional outlet and as a source of inspiration for the novel she hoped to write about her time in hiding. Thanks to the efforts of helpers Miep Gies and Bep Voskuijl, the diary was preserved, and thanks to her father, Otto Frank, Anne’s account of the Annex was published after the war.

Anne’s diary reveals that Margot also kept a diary. On 14 October 1942, Anne wrote: “Last night Margot and I lay together in my bed. It was incredibly small, but that made it rather funny. She asked if she could read my diary. I said she could read certain parts of it, and then I asked about hers. She said I could read that too.” Unlike Anne’s diary, Margot’s diary has not survived.

The bond between the sisters

Anne frequently wrote about her sister, who was three years older than she was. Despite their differences, the sisters were very close. On 12 January 1944, Anne wrote: “Margot has become so kind. She seems very different from what she used to be. She is no longer nearly as catty and is becoming a true friend. She no longer regards me as the little nuisance who doesn’t count.”

That bond only grew stronger during the final six months after their arrest and deportation. They remained together until the end. Margot died of typhus in February 1945 in the Bergen-Belsen concentration camp, one or a few days before Anne. Margot was eighteen, or had just turned nineteen; Anne was fifteen years old.
