What's the origin of Peter Out?

The phrase “Peter Out” has a playful history that can be traced back to the 19th century. It is believed to have originated from the mining industry, specifically gold mining, during the California Gold Rush in the 1840s, although an early example can be found in the 1945 Milwaukee Daily Gazette, predating the California Gold Rush.

The exact etymology of the phrase “Peter Out” is a matter of debate. There are some explanations, linking it to Saint Peter, from the Bible, whose faith dwindled shortly before the crucifiction of Jesus Christ. Another theory links it to the French verb “péter”, which literally translates to breaking wind, occurring in an idiom, “Péter dans la main” – “farting in your hand” -, meaning “achieving nothing”.

The most likely explanation, as to the origins of “Peter Out” is Saltpeter, an ingredient of gunpowder – something miners of the 19th century might have been actually familiar with.

The term later transitioned into a more general meaning beyond mining, referring to any situation or thing that gradually loses its effectiveness or momentum.
