Otto Heinrich Frank (12 May 1889 – 19 August 1980) was a German industrialist who later became a resident of the Netherlands and Switzerland. He was the father of Anne and Margot Frank and husband of Edith Frank, and was the only member of his family to survive the Holocaust. He inherited Anne's manuscripts after her death, arranged for the publication of her diary as "Het Achterhuis" in 1947 (known in English as The Diary of a Young Girl), and oversaw its adaptation to both theater and film.
