Otto Frank

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