Origin
Meaning and origin of Kuerth
The surname Kuerth is believed to have its origins in Germany, where it first emerged during the medieval period. It is thought to have been derived from the Old German word "kurz," which means "short" or "brief." This suggests that the name may have been initially bestowed upon someone with a short stature or as a nickname.
One of the earliest recorded instances of the name Kuerth can be found in the Codex Diplomaticus Saxoniae, a collection of historical documents from the region of Saxony, dating back to the 12th century. The entry mentions a certain "Henricus Kurthe" from the town of Merseburg in 1185.
In the 13th century, the name appeared in various forms, such as "Kurthe," "Kurte," and "Kurte," reflecting the regional variations in spelling and pronunciation. One notable individual from this era was Johannes Kurthe, a German monk and scholar who lived from 1245 to 1315.
The Kuerth surname has also been associated with several place names in Germany, such as Kuerten, a town in the Rhineland region, and Kurtzen, a village in Saxony-Anhalt. It is possible that the name originated from one of these locations or was influenced by them.
During the 16th century, the spelling of the name began to solidify into its modern form, "Kuerth." This period saw the rise of several prominent individuals bearing this surname, including Hans Kuerth (1490-1567), a German painter and engraver known for his religious works, and Matthias Kuerth (1532-1603), a Lutheran theologian and reformer.
In the 17th century, the name Kuerth gained further recognition with the birth of Johann Kuerth (1620-1687), a renowned German composer and organist who served at the court of the Elector of Saxony. His works contributed significantly to the development of the German Baroque music tradition.
As the centuries progressed, the Kuerth surname continued to be represented across various fields, such as science, literature, and politics. Notable figures include Friedrich Wilhelm Kuerth (1785-1856), a German mathematician and astronomer, and Heinrich Kuerth (1861-1938), a German politician and member of the Reichstag during the Weimar Republic.

The bar chart below shows how Kuerth 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 Kuerth surname at the time of the 2020 Census, not any inherent property of the name itself.
