After Otto was unable to find a publisher, the work was given to historian Jan Romein, who was so impressed that he wrote about the diary in a front-page article for the newspaper Het Parool in 1946. The resulting attention led to a publishing deal with Contact, and Het Achterhuis was released on June 25, 1947. An immediate best seller in the Netherlands, the work began to appear elsewhere. In 1952 the first American edition was published under the title Anne Frank: The Diary of a Young Girl; it included an introduction by Eleanor Roosevelt. The work was eventually translated into more than 65 languages, and it was later adapted for the stage and screen. All proceeds went to a foundation established in Anne’s honour. In 1995, 15 years after Otto’s death, a new English version of the Diary was published. It contained material that had been previously omitted. In an effort to extend the copyright date—which was to begin expiring in various European countries in 2016—Otto was added as a coauthor in 2015.
Peter Longerich argues that the search for a finite date on which the Nazis embarked upon the extermination of the Jews is futile, in his book Holocaust: The Nazi Persecution and Murder of the Jews (2011). Longerich writes: "We should abandon the notion that it is historically meaningful to try to filter the wealth of available historical material and pick out a single decision" that led to the Holocaust.[116][117]
Mengele sailed to Argentina in July 1949, assisted by a network of former SS members. He initially lived in and around Buenos Aires, then fled to Paraguay in 1959 and Brazil in 1960, while being sought by West Germany, Israel, and Nazi hunters such as Simon Wiesenthal who wanted to bring him to trial. He eluded capture in spite of extradition requests by the West German government and clandestine operations by the Israeli intelligence agency Mossad. He drowned in 1979 after suffering a stroke while swimming off the Brazilian coast, and was buried under a false name. His remains were disinterred and positively identified by forensic examination in 1985.
