Karl Kilbom (8 May 1885 – 24 December 1961) was a Swedish politician and one of the founders of the Communist Party of Sweden. Youth As the son of a blacksmith, Karl Kilbom grew up in a working class family of Walloon origin in the small town of Österbybruk outside Uppsala, where he started working in the steel mills at an early age.
