Annelies Marie "Anne" Frank (German: [ʔanəliːs maˈʁiː ˈʔanə ˈfʁaŋk]; Dutch: [ʔɑnəˈlis maˈri ˈʔɑnə ˈfrɑŋk]; 12 June 1929 – February or March 1945) was a German-born diarist. One of the most discussed Jewish victims of the Holocaust, she gained fame posthumously with the publication of The Diary of a Young Girl (originally Het Achterhuis in Dutch; English: The Secret Annex), in which she documents her life in hiding from 1942 to 1944, during the German occupation of the Netherlands in World War II. It is one of the world's most widely known books and has been the basis for several plays and films.

People with a grudge against the world are always dangerous. They seem to think life owes them something. I’ve known many who have suffered worse and been cut off from life much more…and they’ve managed to lead happy contented lives. It’s what’s in yourself that makes you happy or unhappy.
Just to be in love seemed the most blissful luxury I had ever known. The thought came to me that perhaps it is the loving that counts, not the being loved in return—that perhaps true loving can never know anything but happiness. For a moment I felt that I had discovered a great truth.
