by Konstantin Raitio
Born in Urjala in 1855, Konstantin "Kosti" Raitio was a Finnish educator, writer, and maker of school textbooks. He studied at the University of Helsinki, earned a degree in philosophy, and became closely connected with teacher training and public education.
Raitio is remembered especially for his work as a seminary director and for writing and editing materials for elementary schools. His books and songs were created for practical classroom use, and his name appears on many reading books and other teaching texts used in Finnish schools.
He died in Helsinki in 1924. Although he is not widely known outside Finland today, his influence lived on through the everyday school reading of countless children and through his place in the history of Finnish education.
