Gunnarsen

Gunnarsen is a Danish and Norwegian patronymic surname meaning "son of Gunnar." The given name Gunnar derives from the Old Norse Gunnarr, composed of the elements gunnr "war" and herr "army, warrior," making it a cognate of Gunther. In Norse legend, Gunnar was the husband of Brynhildr who was involved in the tragic story of Sigurd.

The surname Gunnarsen is common in Denmark and Norway, where patronymic naming traditions using -sen or -son suffixes are widespread. In Sweden, the equivalent form is Gunnarsson. Although the name may appear in historical records, notable modern bearers are few. One Danish individual is Lars Gunnarsen, a professor at Aalborg University specializing in indoor climate and ventilation research. His work focuses on achieving safe and healthy home environments and has highlighted the importance of indoor climate as a driver for innovation in construction.
