Her husband was Icelandic Nobel Literature laureate Halldór Laxness, and Auður worked as his secretary and writing collaborator for many years.

[1] Auður was born in the Icelandic village of Eyrarbakki on 20 July 1918,[2] to Halldóra Kristín Jónsdóttir and Sveinn Guðmundsson.

[3] The couple had two daughters, Sigríður and Guðný, and they lived in a house called Gljúfrasteinn, located in Mosfellsbær.

[4] Auður held a position on the editorial board of crafts magazine Hugur og hönd, producing articles on traditional Icelandic handicrafts such as weaving and knitting.

[8] Another theory suggests that Auður brought back a version of the sweater after a trip to Greenland and replicated it herself during the late 1940s, inspired by old Icelandic patterns and imported embroidery techniques.
