Origin
The surname Assmann originated in Germany and can be traced back to the 13th century. It is believed to have derived from the Germanic personal name "Asmund" or "Osmund," which means "divine protection." The name was likely first adopted as a surname by individuals residing in the regions of Saxony, Thuringia, and Silesia.
One of the earliest recorded instances of the Assmann surname appears in the town records of Bautzen, located in the present-day state of Saxony, Germany. In 1312, a certain "Johannes Assman" was listed as a resident of the town.
The surname Assmann also appears in various medieval documents and records, including the Codex Diplomaticus Saxoniae Regiae, a collection of historical documents from the Kingdom of Saxony. In this collection, there are references to individuals bearing the name Assmann in the 14th and 15th centuries.
During the 16th century, the surname Assmann spread across different regions of Germany, with notable individuals bearing this name. One such person was Johann Assmann (1525-1592), a German theologian and reformer from Saxony, who played a significant role in the Protestant Reformation.
Another notable figure was Georg Assmann (1565-1643), a German mathematician and astronomer from Thuringia. He made contributions to the development of logarithms and published several works on astronomy and mathematics.
In the 18th century, the Assmann surname gained prominence in the literary and academic circles of Germany. Friedrich Assmann (1742-1794) was a German poet and educator from Saxony, known for his writings on education and pedagogy.
The 19th century saw the rise of several individuals with the Assmann surname in various fields. One such person was Wilhelm Assmann (1822-1911), a German artist and painter from Saxony, renowned for his landscape paintings and depictions of rural life.

Demographics
Among Census respondents with the surname Assmann, the largest self-reported group is White at 91.4%. The next largest groups are Hispanic (4.5%) and Two or More Races (3.0%).
The bar chart below shows how Assmann 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 Assmann surname at the time of the 2020 Census, not any inherent property of the name itself.
