I translated this article from the German Wikipedia, "Sigurd Savonius", oldid=116240887. This was the best and most detailed information I could find. It still needs more secondary sources, but the Talk page of the German article has an extensive discussion about sources, so there might be some information there. Also probably in Finnish, but I don't read Finnish, so I don't really know what's out there. Margin1522 (talk) 04:56, 24 April 2014 (UTC)[reply]
