History & Origin

Watt reaches back to Wat, the friendly medieval clipping of Walter, and hardened into a family surname before a handful of American parents revived it as a first name. Through Walter it means 'ruler of the army.' It shows up in US birth records from the late eighteen-hundreds onward.

Watt was only about fifteen a year even at its peak, and it had all but vanished from birth records by the nineteen-seventies. A boy named Watt in its heyday would sit in a great-grandparent's generation today, an unmistakably old-fashioned choice.

Did you know? The Scottish engineer James Watt gave his surname to the unit of electrical power, which kept the short, blunt name familiar long after it faded as a given name.
