Origin
The surname Rettenmaier is of German origin, originating in the regions of southern Germany. It is believed to have emerged during the medieval period, around the 12th or 13th century.
The name Rettenmaier is derived from two Old German words: "retten" meaning "to rescue" or "to save," and "maier" or "mayer," which was an occupational surname referring to a manager or overseer of a farm or estate. Therefore, the name Rettenmaier likely referred to someone who was a bailiff or steward responsible for managing and protecting the lands and properties of a noble or landowning family.
One of the earliest recorded instances of the name Rettenmaier can be found in the Stammheim Chronicle, a historical record from the town of Stammheim in Baden-Württemberg, dating back to the late 15th century. This document mentions a Hans Rettenmaier, who was a prominent citizen of the town in the year 1487.
In the 16th century, there are records of a wealthy merchant family named Rettenmaier residing in the city of Augsburg, which was a major trading center in southern Germany during the Renaissance period. Notable members of this family include Johann Rettenmaier (1512-1588), a successful textile merchant, and his son, Michael Rettenmaier (1542-1617), who served as a city councilor in Augsburg.
Another notable figure with the surname Rettenmaier was Friedrich Rettenmaier (1785-1858), a German jurist and professor of law at the University of Tübingen. He was a respected scholar in the field of Roman law and published several influential works on legal theory.
In the 19th century, a branch of the Rettenmaier family settled in the town of Ellwangen in Baden-Württemberg. One of their descendants, Karl Rettenmaier (1871-1942), was a prominent architect and urban planner who designed several notable buildings in Stuttgart and other cities in southern Germany.
Another individual of note was Katharina Rettenmaier (1906-1989), a German artist and painter known for her expressionist and abstract works. She studied at the Staatliche Akademie der Bildenden Künste in Stuttgart and had several solo exhibitions throughout her career.
While the surname Rettenmaier is not among the most common in Germany today, it has a rich history and has been associated with various notable figures over the centuries, particularly in the regions of southern Germany where the name originated.
Demographics
Among Census respondents with the surname Rettenmaier, the largest self-reported group is White at 94.7%. The next largest groups are Two or More Races (5.3%).
The bar chart below shows how Rettenmaier 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 Rettenmaier surname at the time of the 2020 Census, not any inherent property of the name itself.
