Tagebuch der Anne Frank
Johannes Kleiman (17 August 1896 – 28 January 1959) was one of the Dutch residents who helped hide Anne Frank and her family during the Nazi occupation of the Netherlands. In the published version of Frank's diary, "The Diary of a Young Girl", he is given the pseudonym Mr. Koophuis. In some later publications of the diary, the pseudonym was removed, and Kleiman was referred to by his real name.
