Niilo Kallio

Born in Uskela on February 27, 1890, and died in Helsinki on December 13, 1968, he was a Finnish teacher, educational scholar, and school administrator. Finnish reference sources describe him as a mathematics teacher from 1914 to 1933 and later a senior official in the National Board of Education, where he served as a school counselor and eventually led secondary-school administration.

He is also remembered as a textbook author and editor, especially in connection with school mathematics. Library and public-domain catalog records show that works under his name are preserved in collections such as Project Gutenberg and other archival databases, reflecting a career that extended beyond the classroom into publishing and educational writing.

Although he was not primarily known as a literary novelist, his name remains of interest to readers today because his published work sits at the crossroads of learning, authorship, and Finnish cultural history.
