Sigmund

Derived from the Germanic elements sigu "victory" and mund "protector" (or in the case of the Scandinavian cognate, from the Old Norse elements sigr "victory" and mundr "protector"). In the Norse Völsungasaga this is the name of the hero Sigurd's father, the bearer of the powerful sword Gram. A notable bearer was the Austrian psychologist Sigmund Freud (1856-1939), the creator of the revolutionary theory of psychoanalysis.
