Origin
Meaning and origin of Immoos
The surname IMMOOS is of German origin, originating in the 16th century. It is derived from the German word "immen," which translates to "bees" or "beehives." This name likely originated in the regions of southern Germany, where beekeeping was a prevalent occupation.
One of the earliest recorded instances of the IMMOOS name can be found in the village of Immenhausen, located in the Hesse region of central Germany. The name of this village, which translates to "houses of bees," suggests a strong connection between the IMMOOS surname and the historical practice of beekeeping in the area.
In the 17th century, Johannes IMMOOS (1621-1687), a well-known beekeeper and author, wrote extensively on the subject of apiculture. His works, such as "Der Vollkommene Bienenmeister" (The Complete Beemaster), were widely read and influenced the beekeeping practices of his time.
The IMMOOS name also appears in various historical records from the 18th and 19th centuries. For instance, Anna Maria IMMOOS (1753-1823) was a prominent figure in the town of Meersburg, located on the shores of Lake Constance in southern Germany. Her family was known for their expertise in beekeeping and honey production.
In the 19th century, Friedrich IMMOOS (1814-1892) was a renowned botanist and naturalist from the Black Forest region of Germany. His extensive research on the flora and fauna of the area, including the behavior of bees, contributed significantly to the scientific understanding of the time.
Another notable figure with the IMMOOS surname was Elise IMMOOS (1877-1962), a German educator and women's rights activist. She was a vocal advocate for equal educational opportunities for women and played a crucial role in establishing several schools and educational programs in her home region of Bavaria.
While the IMMOOS surname may have originated in Germany, it has since spread to other parts of the world through migration and immigration. However, its roots can be traced back to the historical practice of beekeeping in the regions of southern and central Germany, where the name first arose.

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