Origin
The surname Lederman is of German origin, and it first emerged in the Middle Ages. The name is derived from the German word "Leder," which means "leather," and "Mann," which means "man." This suggests that the name may have originally referred to a person who worked with leather, such as a tanner or a shoemaker.
The earliest recorded instances of the name Lederman can be traced back to the 14th century, when it appeared in various German regions. In the 15th century, the name is mentioned in the records of the city of Nuremberg, where a family of tanners bearing the name Lederman resided.
One of the earliest known individuals with the surname Lederman was Hans Lederman, a merchant who lived in the German city of Augsburg in the late 15th century. Another notable figure was Johann Lederman, a Protestant reformer who lived in the 16th century and was known for his writings on theology.
In the 17th century, the name Lederman appeared in various parts of Germany, including the regions of Bavaria and Saxony. During this period, the name was sometimes spelled slightly differently, such as "Ledderman" or "Leddermar."
As the centuries passed, the Lederman surname spread beyond Germany to other parts of Europe and eventually to the Americas. One prominent bearer of the name was Max Lederman (1890-1971), an Austrian-born American mathematician and physicist who made significant contributions to the field of general relativity.
Other notable individuals with the surname Lederman include Victor Lederman (1924-2018), an American experimental physicist who received the Nobel Prize in Physics in 1988 for his work on the discovery of the muon neutrino. Additionally, there was Mordecai Lederman (1886-1975), a Polish-born American Jewish scholar and author who wrote extensively about Jewish history and culture.
While the surname Lederman has its roots in Germany and originally referred to those involved in the leather trade, it has since become more widespread and embraced by individuals from various backgrounds and professions.
Demographics
Among Census respondents with the surname Lederman, the largest self-reported group is White at 91.0%. The next largest groups are Hispanic (5.0%) and Two or More Races (2.5%).
The bar chart below shows how Lederman 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 Lederman 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.
