Origin
The surname Klusmann originates from Germany, specifically from the northern regions of the country. It is believed to have emerged around the 16th century, derived from the Low German word "klus" meaning "hermit" or "recluse." This suggests that the name may have been initially applied to individuals who lived a solitary or hermitic lifestyle.
One of the earliest recorded instances of the Klusmann name can be found in the historical records of the city of Hamburg, where a certain Hans Klusmann is mentioned as a merchant in the year 1587. Another early reference is found in the town of Lüneburg, where a family by the name of Klusmann is recorded as landowners in the late 16th century.
The Klusmann name is also associated with the town of Klußmann, located in the state of Lower Saxony. It is possible that the name originated as a place name, referring to individuals who hailed from this particular town or its surrounding areas.
In the 17th century, a notable figure named Johann Klusmann (1628-1692) was a prominent theologian and author from the city of Lübeck. His works on religious philosophy and moral teachings were widely read during his time.
Another individual of note is Friedrich Klusmann (1786-1857), a German composer and organist who was highly regarded for his contributions to sacred music. He served as the organist at the St. Petri Cathedral in Bremen for over three decades.
In the 19th century, a renowned botanist named Ernst Klusmann (1809-1887) made significant contributions to the field of plant taxonomy. He was particularly known for his extensive research on the flora of northern Germany and the classification of various plant species.
During the 20th century, a notable figure was Hans Klusmann (1901-1986), a German architect who played a crucial role in the reconstruction of several cities in Germany after World War II. His innovative designs and urban planning efforts were widely acclaimed.
Another important personality was Maria Klusmann (1922-2005), a German writer and journalist. Her works, which often explored themes of social justice and human rights, gained widespread recognition and won several literary awards.
While the Klusmann name has its roots in northern Germany, it has since spread to other parts of the country and beyond, with individuals bearing this surname making significant contributions in various fields throughout history.
Demographics
Among Census respondents with the surname Klusmann, the largest self-reported group is White at 80.1%. The next largest groups are Hispanic (10.6%) and Two or More Races (4.6%).
The bar chart below shows how Klusmann 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 Klusmann surname at the time of the 2020 Census, not any inherent property of the name itself.
