Carl Ferdinand Nordlund

Carl Ferdinand Nordlund lived from 1820 to 1905. Project Gutenberg lists him as the author of Kuvaelmia menneitten aikojen eloista ja oloista and notes that he also used the alias K. Pohjanen.

Based on the limited source material I could confirm here, he appears to have been a Finnish-language author interested in depicting life and customs of earlier periods. That gives his work a historical and cultural flavor, even in literary form.

I wasn't able to confirm fuller biographical details such as his birthplace, career outside writing, or a reliable portrait image from the sources available in this conversation, so those are best left unstated.
