Origin
Meaning and origin of Lausman
The surname LAUSMAN has its origins in Germany, dating back to the 16th century. It is believed to have derived from the Old German word "laus," meaning "louse" or "flea," combined with the word "man," indicating a person who dealt with these pests. This suggests that the name may have originally referred to an exterminator or someone involved in the control of fleas and lice.
One of the earliest recorded mentions of the LAUSMAN name can be found in the Church records of Saxony from the late 1500s. It appears that the name was predominantly concentrated in the regions around Dresden and Leipzig during this time period. The spelling variations included "Laussman," "Lausmann," and "Laussmann."
In the 17th century, the LAUSMAN surname gained prominence with the birth of Johann Friedrich Lausman (1628-1701), a renowned Lutheran theologian and professor at the University of Leipzig. His works on theology and biblical exegesis were widely circulated throughout Europe during his lifetime.
Another notable figure bearing this surname was Carl Lausman (1795-1876), a Prussian military officer who served in the Napoleonic Wars and later became a celebrated painter. His landscapes and battle scenes were highly acclaimed, and many of his works can be found in museums across Germany.
In the early 19th century, the LAUSMAN family spread beyond Germany, with some members migrating to the United States. One such individual was Wilhelm Lausman (1820-1892), who settled in Pennsylvania and established a successful textile business. His descendants continued to carry on the family name in the United States.
The name LAUSMAN also appeared in other parts of Europe, including the Netherlands and France. In the Netherlands, there was a prominent family of merchants known as the Lausmans, who were based in Amsterdam during the 17th and 18th centuries. Their trading activities spanned across the Dutch East Indies and beyond.
Another noteworthy individual was Marie-Thérèse Lausman (1862-1928), a French sculptor and artist who was recognized for her intricate marble statues and busts. Her works were exhibited in various salons and galleries in Paris during the late 19th and early 20th centuries.
While the LAUSMAN surname may have originated from a somewhat unusual occupation, it has since been carried by individuals from diverse backgrounds, including scholars, artists, military figures, and entrepreneurs. The name's journey through history reflects the rich tapestry of human experiences and the enduring legacy of surnames.

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