Origin
The surname Koppman is of German origin, originating in the northern regions of Germany and the Low Countries during the late medieval period. It is derived from the Old German word "kopp," meaning "head," and the suffix "-man," signifying "man" or "person." Thus, the name Koppman likely referred to a person with a distinctive physical feature, such as a large or unusually shaped head.
Historical records indicate that variations of the name, such as Kopman and Koppmann, appeared in documents and manuscripts from the 14th century onward. One of the earliest known references is found in the Lübeck City Archives, which mentions a Johannes Kopman in a legal document dated 1382.
The Koppman surname can be traced back to several prominent figures throughout history. One notable example is Johann Koppmann (1668-1732), a German theologian and author who published works on theology and philosophy. Another is Heinrich Koppmann (1835-1905), a German historian and archivist who made significant contributions to the study of medieval German history.
In the 19th century, the Koppman name gained recognition through the works of Karl Koppmann (1839-1905), a German philologist and linguist who specialized in the study of Low German dialects. His extensive research and publications on the subject helped to preserve and document the linguistic heritage of northern Germany.
Another notable figure bearing the Koppman surname is the German artist and illustrator Eduard Koppmann (1856-1925), whose works were widely exhibited and acclaimed during his lifetime. His illustrations and etchings often depicted scenes from daily life and the natural world.
In the realm of literature, the name Koppman is associated with the German writer and poet Karl Friedrich Koppmann (1866-1940), whose works explored themes of nature, romanticism, and the human experience.
While the surname Koppman has its origins in northern Germany and the Low Countries, it has since spread to various parts of the world through emigration and migration. However, the earliest recorded instances and historical figures bearing this name can be traced back to the regions of its origin.
Demographics
Among Census respondents with the surname Koppman, the largest self-reported group is White at 85.4%. The next largest groups are Hispanic (6.3%) and Two or More Races (6.3%).
The bar chart below shows how Koppman 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 Koppman surname at the time of the 2020 Census, not any inherent property of the name itself.
