author
1812–1875
Best known for a 19th-century etiquette guide, this German-language writer focused on practical instruction rather than literary fame. His surviving works suggest a teacherly voice shaped by language learning, everyday conduct, and useful knowledge.

by Ignaz Lehmann
Ignaz Lehmann (1812–1875) is a little-known 19th-century German-language author whose works that remain easy to trace today are mainly practical books rather than novels. Public catalog and book records connect him with Die Regeln des Anstands, der Höflichkeit und der guten Sitte, an etiquette manual that was later preserved by Project Gutenberg, along with several language textbooks.
Those titles suggest a writer interested in education and self-improvement. Lehmann appears to have written for readers who wanted clear guidance, whether on social behavior or on learning English and French, and that makes his work feel closely tied to everyday life in the period.
Because reliable biographical information about him is scarce in the sources I could confirm here, it is safest to describe him through his published work: a practical author whose books offer a small but revealing window into middle-19th-century ideas about manners, schooling, and useful knowledge.
