Ketty Andreasen lived with her husband, the municipal employee Svend Andreasen, in Gilleleje on the Danish coast. Hundreds of Jews hid in this fishing village at the end of September 1943, waiting for an opportunity to cross to Sweden by boat to evade deportation. Svend Andreasen took food and clothing to the escaping Jews.
The Andreasens suggested to Paula Warschaffsky Mortensen, who had fled Copenhagen, that her three-year-old daughter Tove could stay with him them. Her mother agreed, and embarked on the dangerous journey to Sweden alone. Tove missed her mother a great deal, but the Andreasens took loving care of her.
After Denmark’s liberation in 1945, Paula Warschaffsky Mortensen took back her daughter, now aged five. The child no longer recognized her, and wanted to be with her foster parents. Tove visited the Andreasens in Gilleleje as often as possible. Seeing Tove suffering more and more from the separation, her mother eventually allowed her to return to Gilleleje. Sven and Ketty Andreasen took care of Tove Warschaffsky Mortensen until shew grew up.
