Origin
The surname Kuefner is of German origin, originating in the southern regions of the country. It is believed to have derived from the Middle High German word "kufer," which referred to a cooper or barrel-maker. This occupational surname likely emerged in the late medieval period, around the 13th or 14th century.
One of the earliest recorded instances of the name can be found in the town records of Augsburg, Bavaria, dating back to the year 1482. The entry mentions a certain Hans Kuefner, a cooper by trade. Another early reference comes from the village of Rothenburg ob der Tauber in Franconia, where a Kuefner family is documented as residing in the 16th century.
The spelling of the name has undergone some variations over time, with alternative forms such as Küfner, Kueffner, and Kufner appearing in historical documents. These variations likely stemmed from regional dialects and the evolution of the German language.
Interestingly, the name Kuefner is also associated with a small village called Küfnerhof, located in the district of Reutlingen, Baden-Württemberg. This place name is believed to have derived from the Kuefner surname, possibly indicating that a family of coopers once lived or worked in the area.
Notable individuals with the surname Kuefner include Johann Kuefner (1780-1855), a German composer and organist who lived and worked in Augsburg. Another prominent figure was Theodor Kuefner (1843-1917), a German politician and lawyer who served as a member of the Reichstag (German parliament) in the late 19th century.
In the realm of arts and literature, the name Kuefner is associated with the German writer and poet Max Kuefner (1892-1962), known for his works depicting rural life in Bavaria. Additionally, the American artist and illustrator Walter Kuefner (1917-1995) gained recognition for his illustrations in magazines such as Sports Illustrated and National Geographic.
Lastly, a noteworthy figure in the field of science was the German physicist and engineer Ernst Kuefner (1890-1970), who made significant contributions to the development of aerodynamics and aircraft design during the early 20th century.
Demographics
Among Census respondents with the surname Kuefner, the largest self-reported group is White at 96.6%. The next largest groups are Two or More Races (2.6%) and Hispanic (0.9%).
The bar chart below shows how Kuefner bearers described their own race and ethnicity on the 2020 Census form. The Census Bureau groups responses into six broad categories: White, Black or African American, Hispanic or Latino, Asian and Pacific Islander, American Indian and Alaska Native, and Two or More Races. When a category has too few respondents for a given surname, the Bureau suppresses the figure to protect individual privacy, which is why some names show fewer than six slices.
Percentages are shown for every Census year so the breakdown stays comparable over time. When the source file also includes raw headcounts, Name Census shows those alongside the percentages in the legend.
Keep in mind that these are self-reported numbers. A person's surname does not determine their race or ethnicity, and the distribution you see here reflects the specific population who happened to carry the Kuefner surname at the time of the 2020 Census, not any inherent property of the name itself.
