Kieffer: origin and meaning of the surname

Kieffer is a trade name. In the dialects spoken between the Rhine and the Moselle, a Kieffer was a cooper: the craftsman who made and repaired barrels, vats and tubs. The genealogist Jean Tosti sums it up: found in Alsace and Lorraine, the name corresponds to the cooper’s trade, Küfer in German.

From Küfer to Kieffer

Standard German calls the cooper Küfer, a word built on Kufe, a tub or vat. Most dialects of southern and central Germany pronounce the rounded vowel ü as a plain i. Linguists call this unrounding (Entrundung): the same shift turns Schlüssel (key) into Schlissel. Spoken this way, Küfer becomes Kiefer, and the local forms of the name show that this is what happened between the Rhine and the Moselle.

Luxembourg shows the link clearly. Researchers on the Luxembourg surname atlas project at the University of Luxembourg give the surname Kieffer as the Luxembourgish word Kéifer, meaning cooper. In Luxembourg, then, the name is still close to an everyday word.

In Alsace, Lorraine and Luxembourg, a Kieffer was simply “the cooper”.

Why a trade became a name

Many European surnames grew out of a person’s occupation, place of origin, father’s name or a nickname. An occupational surname first described one person: Hans the cooper. Over generations it became fixed and passed to children, whatever their own trade.

Two consequences follow:

• There is no single Kieffer ancestor. Coopers worked in every wine-growing and brewing town, so the name arose independently in many places. Two Kieffer families need not be related.
• The name tells you about one ancestor’s job, centuries ago, not about the trade of later generations.

Spellings and related names

The same word gave several spellings. You will meet them in the same family, and sometimes in the same parish register:

Coopers had other names too. Depending on the region, German speakers said Böttcher, Büttner, Binder or Fassbinder, and Schäffler. All of these are also surnames today. The article on the cooper’s trade explores them.

Other theories, and how much weight to give them

Some sources offer other explanations. They are worth knowing, but they fit the Kieffers of the Rhine and Moselle less well:

• Pine tree. In standard German, Kiefer also means pine, and Kiefer can mean jaw. A surname from a place name or a nickname is possible for some German Kiefer families. It does not explain why the Alsatian and Luxembourgish forms sound exactly like the local word for cooper.
• A grumpy man. The French genealogy site Filae mentions a nickname from Middle High German kiffen, “to scold”. It presents this alongside the cooper meaning, which remains the explanation given by the specialist sources above.

No such thing as a “Kieffer coat of arms”

Websites and shops sell “the Kieffer family crest”. Heraldic authorities are clear that there is no coat of arms for a surname. As the College of Arms explains, arms belong to the specific person to whom they were granted, and to that person’s descendants. Many people with the same surname are entitled to completely different arms, or none at all. A crest sold for a surname is a decoration, not a piece of family history.
