Kurt Aust

Kurt Aust is a pseudonym for Kurt Østergaard (born 6 December 1955), a Danish-Norwegian author and freelance writer.

Østergaard trained as a teacher. He has been living in Horten in Norway since 1982.

Østergaard debuted using the name Aust as a novelist in 1999. Prior to this, he had written the script for a historically based cartoon on the slave ship Fredensborg.

He has written several historical crime novels based on Denmark–Norway around the beginning of the 18th century. The main characters in these novels are Professor Thomas af Boueberg of Copenhagen University and his Dr. Watson equivalent, the considerably less brilliant Norwegian Petter Hortten.

In 2006 he published his first contemporary novel, the thriller De usynlige brødre (The Invisible Brothers) (translated into 8 languages) and his first children's book Kasper & Måns. Den store kaosdagen (Kasper & Måns. The Great Day of Chaos).

Kurt Østergaard is married to the artist Kin Wessel (Ann-Carin Wessel). She has co-illustrated the cartoon about Fredensborg and the children's book Kasper & Måns. Den store kaosdagen.
