author
1826–1896
A 19th-century Finnish land surveyor who also wrote fiction and used the pen names P.W.A. and r-m-n. His life bridged practical public work and literary activity in a period of growing Finnish-language culture.

by Petter Wilhelm Aurén
Born on September 4, 1826, in Nilsiä and died on May 24, 1896, in Oulu, he is described in available reference sources as a Finnish land surveyor and writer. Finnish Wikipedia also notes the name form Pekka Ville Eronen alongside Petter Wilhelm Aurén, and says he wrote under the pseudonyms P.W.A. and r-m-n.
The surviving readily confirmed biographical record appears quite brief, but it suggests an author whose writing grew out of a working life outside the literary center. That combination of surveying and authorship gives him the feel of many 19th-century Nordic writers whose books were shaped by local knowledge, travel, and everyday society.
Because the accessible source material I found is limited, it is best to keep the portrait of his life modest and factual: a Finnish writer of the 1800s, active alongside a career in land measurement and public work, and remembered today through bibliographic and encyclopedia records rather than a large modern popular profile.
