Werner
Meaning
defending army (werin 'defend' + heri 'army'); famously borne by Werner Heisenberg, physicist known for the uncertainty principle of quantum mechanics
The story
Werner is old Germanic soldier stock, built from elements meaning to defend and army, a name that marched through the Middle Ages and stayed a standard in German-speaking countries ever after. Physics gave it its sharpest edge: Werner Heisenberg, who in his twenties helped invent quantum mechanics and whose uncertainty principle, the discovery that nature sets a hard limit on what can be known at once, made his first name a byword for the strangeness of the modern world. In the United States, Werner has been an old, quiet presence in the records, carried along by German immigrant families, never common and never quite vanishing, with a small fresh stirring in the most recent decade. For parents after something Teutonic and cerebral, it is a deep cut with a very sharp mind attached.
