Origin
The surname Mentzer has its origins in Germany, with records dating back to the 16th century. It is believed to have derived from the German word "Mentzer" or "Mentzger," which referred to a butcher or meat dealer. This occupation-based surname was common in many German-speaking regions during that time period.
One of the earliest recorded instances of the name Mentzer can be found in the town of Heidelberg, where a family of butchers bearing this surname resided in the late 1500s. The Mentzer name also appeared in various church records and municipal documents throughout the Rhineland area in the 17th and 18th centuries.
In the early 1700s, a prominent figure named Johann Mentzer (1677-1743) rose to prominence as a respected Lutheran theologian and scholar in the city of Giessen. His published works on theology and philosophy were widely studied across German universities during his lifetime.
As the Mentzer family continued to grow and spread across Germany, some members eventually migrated to other parts of Europe and beyond. In the late 18th century, a man named Wilhelm Mentzer (1768-1831) left his homeland and settled in the Russian Empire, where he established a successful business as a merchant and landowner.
One of the most notable figures with the Mentzer surname was the American artist and illustrator Frank Mentzer (1939-2018). Born in California, he gained recognition for his work with the Dungeons & Dragons fantasy role-playing game, contributing artwork and serving as a lead designer for several editions.
Another individual of note was the German-American businessman and industrialist Carl Mentzer (1865-1942), who founded the Mentzer Wire Company in Ohio and played a significant role in the development of the wire manufacturing industry in the United States.
Despite its German origins, the Mentzer surname has since spread across various parts of the world, with families bearing this name found in countries such as the United States, Canada, Australia, and beyond. However, the rich history and legacy of this surname can be traced back to its humble beginnings in the butcher's trade of 16th-century Germany.
Demographics
Among Census respondents with the surname Mentzer, the largest self-reported group is White at 92.8%. The next largest groups are Two or More Races (3.2%) and Hispanic (2.4%).
The bar chart below shows how Mentzer 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 Mentzer 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.
There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy. For 2020, the Bureau also published raw group counts rather than direct percentages, so Name Census converts those counts back into shares for comparability across census years.
