Niels

Meaning

victory of the people (form of Nicholas); famously borne by Niels Bohr, physicist who developed the modern model of the atom

The story

Niels is the Scandinavian everyday form of Nicholas, victory of the people in the original Greek, so common in Denmark for so long that it reads as practically Danish itself. Its towering bearer is Niels Bohr, the Copenhagen physicist who in 1913 gave the world the modern picture of the atom, electrons holding to fixed orbits around a nucleus, and whose institute became the meeting ground where a generation hammered out quantum theory. He won the Nobel Prize in 1922 and, in 1943, fled occupied Denmark by boat ahead of arrest. In American records Niels has remained a true rarity, registering its first small presence only in the most recent decade, which leaves it wide open: a crisp Nordic classic that almost no American child carries, with one of history's warmest great minds behind it.
