Origin
Meaning and origin of Dasen
The surname Dasen originated in Switzerland, with the earliest known records dating back to the late 16th century. It is believed to have derived from the Swiss German word "dase," meaning "to sit" or "to reside." This suggests that the name may have initially referred to a person who lived in a particular location or had a sedentary occupation.
One of the earliest documented references to the name Dasen can be found in the parish records of the village of Zofingen, located in the canton of Aargau, Switzerland. In these records, a man named Hans Dasen is mentioned as a resident of the village in the year 1587.
In the 17th century, the name Dasen began to spread beyond the borders of Switzerland. Records show that a family bearing this surname had settled in the neighboring region of Alsace, which was then part of the Holy Roman Empire. One notable individual from this era was Johann Dasen, a merchant and landowner who lived in the city of Strasbourg from 1642 to 1711.
The 18th century saw the emergence of several prominent figures with the surname Dasen. In 1736, a Swiss theologian and philosopher named Johann Jakob Dasen was born in the town of Aarau. He went on to become a respected scholar and author, publishing works on ethics and moral philosophy.
Another notable Dasen from this period was Johann Friedrich Dasen, a Swiss-German painter and engraver who lived from 1759 to 1840. He is best known for his landscapes and historical scenes, many of which depicted the Swiss Alps and rural life in his homeland.
As the 19th century dawned, the Dasen surname continued to be found across various parts of Europe. In 1812, a German writer and journalist named Karl Dasen was born in the city of Mainz. He gained recognition for his political commentary and satirical works, which often critiqued the social and political climate of his time.
Moving into the 20th century, one of the most celebrated individuals with the surname Dasen was the Swiss architect and designer Max Dasen. Born in 1896 in Geneva, he became renowned for his modernist designs and innovative use of materials. Some of his most notable works include the Ville La Roche housing complex in Geneva and the Swiss Pavilion at the 1939 New York World's Fair.
Throughout its long history, the surname Dasen has been associated with various occupations, from merchants and landowners to scholars, artists, and architects. While its origins may lie in the humble Swiss countryside, the name has since spread across borders and left its mark on diverse fields and disciplines.

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 Dasen surname at the time of the 2020 Census, not any inherent property of the name itself.
