The surname Kieffer is of German origin, often said to be derived from the old Germanic word “kuofa,” which translates to “barrel maker” or “cooper” (Watch the documentary below!). An old variant of Kieffer is Küfer (or Kuefer). Historically, a cooper was someone who made wooden staved vessels, such as barrels, tubs, and other containers—a profession of great importance in times when goods were transported and stored in such vessels. Sometimes the name Kieffer, also spelled “Kiefer” with one F, is said to have originated from the “Kiefer,” which translates to “pine tree.” Imagine individuals living near or working with pine trees—perhaps they were given this name as a means of identification.
