Origin
Meaning and origin of Loehmann
The surname Loehmann is believed to have originated in Germany during the medieval period, likely derived from a place name or an occupational term. The earliest known instances of the name can be traced back to the 13th century in the regions of Bavaria and Franconia.
One possible origin of the name Loehmann is from the Old German word "lohe," which referred to a small woodland or a clearing in a forest. This suggests that the name may have initially been associated with individuals who lived near or worked in such areas, perhaps as woodcutters or charcoal burners.
Another theory suggests that Loehmann is an occupational surname related to the Old German word "loh," which means tanner or leather worker. In this case, the name may have been given to individuals who were involved in the tanning or leather-making trade.
The first recorded mention of the name Loehmann appears in the Würzburg Codex, a document dating back to the late 13th century. This record lists a certain "Henricus Loheman" as a resident of the town of Würzburg in Bavaria.
During the 15th century, the name Loehmann can be found in various other historical documents from the regions of Franconia and Bavaria, such as the Nuremberg Chronicles and the Bamberg Annals. These records often refer to individuals with the name Loehmann as landowners, merchants, or craftsmen.
One notable figure bearing the surname Loehmann was Johannes Loehmann (1492-1567), a German mathematician and astronomer who made significant contributions to the development of logarithms and the calculation of planetary orbits. He was born in the town of Bamberg and spent much of his career at the University of Ingolstadt.
Another prominent individual was Gottfried Loehmann (1619-1678), a German composer and organist who served as the Kapellmeister (chapel master) at the court of the Elector of Brandenburg in Berlin. His compositions, particularly his vocal works, were widely acclaimed during his lifetime.
In the 18th century, the name Loehmann can be found in the records of the city of Cologne, where a family of merchants and bankers with this surname resided. One member of this family, Johann Loehmann (1726-1798), was a successful businessman and philanthropist who donated significant funds to the construction of hospitals and orphanages in the city.
Another noteworthy figure was Wilhelm Loehmann (1845-1919), a German physician and pioneer in the field of radiology. He was one of the first researchers to explore the medical applications of X-rays and made significant contributions to the development of diagnostic imaging techniques.
During the 19th and early 20th centuries, the surname Loehmann spread beyond Germany and can be found in various regions of Europe and the Americas, often associated with individuals of German descent or immigrants from German-speaking areas.

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.
