died one or two weeks after their first meeting; Hans died on 25 February 1945. After the war, it was estimated that only 5,000 of the 107,000 Jews deported from the Netherlands between 1942 and 1944 survived. An estimated 30,000 Jews remained in the Netherlands, with many people aided by the Dutch underground. Approximately two-thirds of this group survived the war. Otto Frank survived his internment in Auschwitz. After the war ended, he returned to Amsterdam in June 1945 where he was sheltered by Jan and Miep Gies as he attempted to locate his family.

In his memoir, he described the painful process of reading the diary, recognizing the events described and recalling that he had already heard some of the more amusing episodes read aloud by his daughter. He saw for the first time the more private side of his daughter and those sections of the diary she had not discussed with anyone, noting, "For me it was a revelation… I had no idea of the depth of her thoughts and feelings… She had kept all these feelings to herself". Moved by her repeated wish to be an author, he began to consider having it
