Origin
The surname Spaner is of German origin, with roots dating back to the Middle Ages. It is derived from the German word "spannen," which means "to stretch" or "to span." This suggests that the name may have initially referred to someone who worked with ropes, cables, or spanned distances, such as a builder or surveyor.
The earliest known records of the Spaner name can be traced back to the late 14th century in various regions of Germany, particularly in the southern and central regions. One of the earliest documented individuals with this surname was Johannes Spaner, a landowner and farmer who lived in the village of Rüsselsheim, near Frankfurt, in the 1380s.
During the 15th and 16th centuries, the Spaner name appeared in numerous municipal records and church registers across various German states. For instance, Hans Spaner, a merchant from Nuremberg, was mentioned in a trade document dated 1472. Additionally, a farmer named Peter Spaner was recorded in the village of Langenselbold, near Hanau, in 1523.
In the 17th century, the Spaner family gained prominence in the city of Leipzig, where several members held respected positions. One notable figure was Johann Spaner (1618-1672), a Lutheran theologian and professor at the University of Leipzig. He was known for his influential works on theology and his efforts in promoting pietism, a movement within Lutheranism that emphasized personal piety and moral living.
Another notable Spaner was Friedrich Spaner (1717-1787), a German jurist and legal scholar from Saxony. He served as a judge in the High Court of Appeal in Dresden and authored several treatises on German legal codes and jurisprudence.
In the 19th century, the Spaner name gained recognition in the field of architecture. One of the most prominent figures was August Spaner (1805-1884), a German architect from Berlin. He designed several notable buildings, including the Friedrichswerder Church and the Old Palace in Berlin.
Other historical figures with the Spaner surname include Karl Spaner (1872-1957), a German businessman and industrialist who founded the Spaner-Werke, a successful manufacturing company in Berlin, and Wilhelm Spaner (1890-1963), a German painter and printmaker known for his landscape and architectural depictions.
Demographics
Among Census respondents with the surname Spaner, the largest self-reported group is White at 92.2%. The next largest groups are Hispanic (5.8%) and Black (1.0%).
The bar chart below shows how Spaner 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 Spaner surname at the time of the 2020 Census, not any inherent property of the name itself.

No. The Census Bureau only publishes surnames that appeared at least 100 times in a given decennial Census. That means very rare surnames are excluded entirely, and a surname can appear in one Census release but disappear from a later one if it falls below the reporting threshold.
