Eirik Hornborg (1879-1965) was a Finnish politician, teacher, rhetorician, author and one of its leading and most prolific historical writers, much of his work relating to his country's military history. He is credited with over 1400 published writings including 54 books. He had seen brief wartime service at the age of 36 as a volunteer in a German jaeger battalion fighting the Russians on the eastern front 1916-17, and wrote of his experiences in a memoir in 1959. He was chairman of the Swedish Literary Society in Finland 1934-47 and received honorary doctorates at both the University of Stockholm (1936) and Helsinki (1950). A recent biography summarizes Hornborg's character as a 'fearless truth seeker and rights campaigner.'
