Onni E. (Onni Elias) Helkiö

Born in the rural district of Rauma in 1874, he was a Finnish lecturer, composer, and poet. Sources agree that his family name was Hellman until 1896, and that he later became known as Onni E. Helkiö.

He studied at the University of Helsinki and worked in education for much of his life, while also writing and composing. Reference sources describe him especially as a teacher of Finnish and as a literary figure whose career connected scholarship, music, and poetry.

His bibliography includes poetry and other literary work, and library records and public-domain listings show that a substantial number of his texts have been preserved and digitized. He died in Helsinki in 1961, just one day before his 87th birthday.
