by Olivier August Johan Carlenius
Born in Savonlinna on September 27, 1841, Olivier August Johan Carlenius was a Finnish poet who wrote under the name O. A. J. Keinänen. He studied at the Porvoo gymnasium, entered the University of Helsinki, and completed a degree in philosophy in 1872.
His best-known book is Suomalaisia lauluja, a poetry collection published in Helsinki in 1867. The work helped place him among 19th-century Finnish poets, and it remains the title most closely associated with his name.
Later accounts describe his life becoming overshadowed by mental illness, reportedly after an unhappy love affair. He died in Heinävesi on September 25, 1904. No suitable verified portrait image was found from the sources checked, so a profile image is not included.
