Edwin Tietjens (20 March 1894, Saint Petersburg - 22 May 1944) was a psychiatrist in Berlin in the 1920s and 1930s and resistance fighter against the Nazis.
Tietjens had a doctorate in philosophy. In 1926 he became the fourth husband of Luigina von Fabrice.[1] His 1929 book Desuggestion, translated into English, was widely reviewed. In 1943 Tietjens and his wife Gina hid a Jewish shoe worker, Ruth Heynemann, and her mother, finding them false papers and taking care of them in their Berlin house. After Tietjens died of a heart attack, his wife continued to look after the women until the Russian army arrived. For this they have been recognized as among the Righteous Among the Nations.[2]
