Origin
Meaning and origin of Klussmann
The surname Klussmann originates from Germany, with its earliest known records dating back to the 16th century. The name is believed to have derived from the German word "Klusse," which means "clump" or "lump," possibly referring to a person's physical appearance or occupation.
One of the earliest known references to the name Klussmann can be found in the church records of the town of Kirchheim unter Teck, located in the German state of Baden-Württemberg. In 1587, a record mentions a certain Hans Klussmann, who was a local blacksmith.
As the name spread across Germany, it underwent various spelling variations, such as Klußmann, Klussmann, and Klußman. These variations were likely due to regional dialects and the inconsistencies in record-keeping during that time period.
In the 18th century, the Klussmann name appeared in the records of the city of Hamburg, where a merchant named Johann Klussmann (1712-1788) was a prominent figure in the local trade guild. His son, Friedrich Klussmann (1745-1819), continued the family's mercantile tradition and expanded their business operations.
Another notable Klussmann was Heinrich Klussmann (1825-1905), a German theologian and academic who served as a professor at the University of Bonn. He authored several influential works on biblical exegesis and was widely respected in his field.
During the 19th century, the Klussmann name also gained prominence in the field of music. Carl Klussmann (1823-1892), a German composer and conductor, was celebrated for his operas and orchestral works, which were performed throughout Europe.
As German emigration increased in the late 19th and early 20th centuries, the Klussmann name began to spread beyond Germany's borders. One such example is Wilhelm Klussmann (1875-1957), a German-American artist and illustrator who settled in New York City and became renowned for his portraiture and landscape paintings.
It is worth noting that the Klussmann surname has maintained a strong presence in Germany over the centuries, with many people bearing this name still residing in various regions of the country today.

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 Klussmann surname at the time of the 2020 Census, not any inherent property of the name itself.
