K. N. (Kalle Nikodemus) Rauhala

Kalle Nikodemus Rauhala (1887–1937) was a Finnish writer, journalist, and cooperative movement figure. Sources in the National Library of Finland and the Finnish Wikipedia record that he was born in Jämsä on June 1, 1887, died in Helsinki on March 22, 1937, and was known until 1906 by the surname Fredman.

He wrote under several pen names, including Ilmari Kankari, Johannes Karma, Nikodemus, and Kaarlo Raula. Library records show a wide range in his output: political and social commentary, popular nonfiction, historical writing, and works connected with the cooperative world. He is also remembered for contributing humorous pieces under the name "Nikodemus" in Ylioppilaslehti.

For audiobook listeners today, Rauhala is especially interesting because his surviving books include Maailman loppu, an early Finnish speculative novel, as well as nonfiction such as Bolshevismi ja olot Venäjällä. That mix of public debate, journalism, and imaginative fiction gives his work a lively snapshot of Finnish writing in the early 20th century.
