Origin
The surname Kempert originated in Germany, with the earliest known records dating back to the 13th century. The name is believed to have derived from the Old German word "kembart," which means "warrior with a comb-like helmet." This suggests that the name may have been given to soldiers or warriors who wore distinctive helmets adorned with comb-like protrusions.
One of the earliest documented instances of the name Kempert can be found in the records of the town of Cologne, where a certain Henrich Kempert was listed as a resident in the year 1289. Another early record comes from the city of Nuremberg, where a man named Johann Kempert was recorded as a member of the local guild of tailors in 1342.
During the Middle Ages, the Kempert name appeared in various historical documents and records across German-speaking regions. For example, a man named Ulrich Kempert was mentioned in a manuscript from the Benedictine monastery of St. Gallen in Switzerland, dated 1428.
In the 16th century, the Kempert surname was found in several areas of what is now modern-day Germany. One notable figure from this period was Hans Kempert (1495-1564), a Lutheran theologian and reformer who played a significant role in the Protestant Reformation in the city of Zwickau.
Another famous bearer of the Kempert name was Johann Kempert (1670-1734), a German composer and organist who served as the Kapellmeister (music director) at the court of the Margrave of Brandenburg-Ansbach.
As the centuries passed, the Kempert surname continued to spread across various regions of Germany and beyond. One prominent individual was Friedrich Kempert (1819-1888), a German-born architect and civil engineer who designed several notable buildings in St. Petersburg, Russia, including the Mikhailovsky Palace.
In the 20th century, one of the most well-known figures with the Kempert surname was Ewald Kempert (1908-1974), a German writer and journalist who served as the editor-in-chief of the influential German news magazine Der Spiegel from 1952 to 1962.
Despite its German origins, the Kempert name has also been found in other parts of Europe and even in North America, likely due to migration and immigration patterns over the centuries.
Demographics
Among Census respondents with the surname Kempert, the largest self-reported group is White at 96.0%. The next largest groups are Two or More Races (3.0%) and Hispanic (1.0%).
The bar chart below shows how Kempert 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 Kempert surname at the time of the 2020 Census, not any inherent property of the name itself.
