Origin
Meaning and origin of Leidenheimer
The surname Leidenheimer originated in the German-speaking regions of Europe, likely in the 16th or 17th century. It is derived from the German words "leiden" meaning "to suffer" and "heimer" meaning "home" or "place of origin." This suggests that the name may have referred to a place where people endured hardship or suffering.
One of the earliest recorded instances of the name Leidenheimer can be found in the baptismal records of St. Michael's Church in the town of Landau, Germany, dating back to the late 1600s. The name is also mentioned in the parish records of the nearby village of Impflingen in the early 1700s.
In the 19th century, the Leidenheimer family began to migrate from Germany to other parts of Europe and the Americas. Johann Leidenheimer, born in 1812 in the village of Diedelsheim, Germany, is documented as one of the first Leidenheimers to settle in the United States, arriving in New Orleans, Louisiana in 1856.
Another notable individual with the Leidenheimer surname was Heinrich Leidenheimer, a German author and poet who lived from 1840 to 1918. His works, which included several volumes of poetry and a collection of short stories, were widely read and celebrated in his native Germany.
In the early 20th century, George Leidenheimer, born in 1889 in New Orleans, founded the Leidenheimer Baking Company, which became renowned for its distinctive New Orleans-style French bread. The company's bakery, located in the Faubourg Marigny neighborhood of New Orleans, has been in operation since 1896 and is still run by descendants of George Leidenheimer.
Another notable figure was Wilhelm Leidenheimer, a German-born American architect who lived from 1865 to 1937. He designed several notable buildings in New York City, including the Ansonia Hotel and the former Wilbraham Apartments, both of which are now designated as historic landmarks.
While the surname Leidenheimer is not particularly common, it has a rich history spanning several centuries and countries, with individuals bearing this name making significant contributions in fields ranging from literature and architecture to the culinary arts.

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