Le Journal d'Anne Frank
In "The Diary of a Young Girl" by Anne Frank, one of the characters is a man named Fritz Pfeffer, under the pseudonym Albert Dussel. In the 1930s Pfeffer met Charlotte Kaletta. Pfeffer and Kaletta moved in together but were forbidden from marrying because of the 1935 Nazi Nuremberg Laws that outlawed marriages between Jews and non-Jews. Charlotta married Pfeffer posthumously in 1950, with retrospective effect to 31 May 1937.
