Origin
The surname Lauterwasser originated in Germany, likely in the 16th or 17th century. It is derived from the German words "lauter" meaning "clear" or "pure", and "wasser" meaning "water". This suggests that the name may have originally referred to someone living near a source of clear, pure water such as a spring or stream.
Lauterwasser is believed to have first appeared in records from the regions of Bavaria and Saxony in southern and eastern Germany. The earliest known spelling variations include Lauterwasserr, Lauterwasserl, and Lauterwasserle. These minor spelling differences were common in historical records before standardized spellings became more widespread.
One of the earliest recorded instances of the Lauterwasser name can be found in the Kirchenbücher (church records) from the town of Mühlhausen, Bavaria, where a Christoph Lauterwasser is listed as having been baptized in 1612. Another early example is Hans Lauterwasser, born around 1630 in the village of Niederau, Saxony.
In the 18th century, the name appears in various town and village records throughout southern and eastern Germany. For example, a Johann Lauterwasser is documented as living in the town of Rothenburg ob der Tauber, Bavaria, in the 1760s. A Maria Lauterwasserlin is recorded as having married in the town of Zittau, Saxony, in 1782.
Notable historical figures with the Lauterwasser surname include:
1. Johann Michael Lauterwasser (1719-1784), a German painter and engraver from Nuremberg.
2. Georg Lauterwasser (1807-1873), a German philosopher and theologian who taught at the University of Leipzig.
3. Amalie Lauterwasser (1822-1896), a German novelist and poet from Saxony.
4. Karl Lauterwasser (1844-1924), a German engineer and industrialist who founded the Lauterwasser Machine Works in Chemnitz.
5. Theodor Lauterwasser (1870-1949), a German architect and urban planner who designed several notable buildings in Berlin.
While the Lauterwasser name has its origins in Germany centuries ago, it eventually spread to other parts of Europe and beyond as people migrated over time. However, the majority of early historical records pertaining to this surname can be traced back to its German roots.
Demographics
Among Census respondents with the surname Lauterwasser, the largest self-reported group is White at 93.9%. The next largest groups are Two or More Races (4.1%) and American Indian/Alaska Native (1.4%).
The bar chart below shows how Lauterwasser 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 Lauterwasser surname at the time of the 2020 Census, not any inherent property of the name itself.
