- Otto Frank (Wikipedia)
Otto Heinrich Frank (12 May 1889 – 19 August 1980) was a German businessman, and the father of Anne Frank. He edited and published the first edition of her diary in 1947 (subsequently known in English as The Diary of a Young Girl) and advised on its later theatrical and cinematic adaptations. In the 1950s and the 1960s, he established European charities in his daughter’s name and founded the trust which preserved his family’s wartime hiding place, the Anne Frank House, in Amsterdam.
