Jalmari Jaakkola

Kaarle Jalmari Jaakkola (1 January 1885 – 12 February 1964) was a Finnish historian and a professor of Finnish history at the University of Helsinki between 1932 and 1954. Jaakkola is known as a historian who primarily researched medieval history and sought to put forth that Finland existed as an entity already during that period. Some of Jaakkola's hypotheses are today considered to be overtly nationalist and outdated, but his influence during his lifetime remains undisputed.

His other research interests included the historical origins of the Birkarls and Kvens, and the historical background of Kalevala epic poetry. Provided by Wikipedia
