A biography of Gertrude van Tijn (1891-1974), born as Gertrud Franzisca Cohn in Braunschweig, Germany. From 1911-15 she lived in London, but was forced to immigrate because of her status as an enemy alien. She then went to Holland, where she became a fervent Zionist. In 1920 she married Jacques van Tijn, a Dutch Jew, and gave birth to two children. As he was a mining engineer, they lived in different countries until 1932 when they returned to Holland; in 1937 they were divorced. Focuses on her life and activities during 1933-45, when she worked for organizations dealing with the resettlement of Jewish refugees from Germany who fled to Holland, as well as with emigration of Dutch Jews, in particular for the Committee for Jewish Refugees. In April-May 1941 van Tijn, with Nazi approval, traveled to Portugal to coordinate, together with Portuguese authorities and the Joint Distribution Committee, the transit of Jewish refugees through Portugal and across the Atlantic. Her task proved to be very difficult, but some Jews got through, including her daughter. Her son served in the Allied army in France and Belgium. Van Tijn became head of the emigration department of the Jewish Council in Amsterdam; however, her achievements in this capacity were modest. In September 1943 she was deported to Westerbork, and in March 1944 to Bergen-Belsen. In the summer of 1944 she was freed with a group of prisoners in exchange for Germans arrested in Palestine. She stayed in Palestine for a few months, traveled back to Europe in 1945, and eventually settled in the USA, living close to her daughter. While in Palestine she wrote a report of what she had witnessed, which is found in the Leo Baeck Archives in New York, but was never published. Soon after the war van Tijn was criticized and censured as a dupe of the Nazis, guilty at the least of false credulity and at the most of collaboration, but she was later exonerated.
