Josip Broz Tito
In 2013 a lot of media coverage was given to unclassified NSA's study in Cryptologic Spectrum that concluded that Tito did not speak the language as a native, and had features of other Slavic languages (Russian and Polish). The hypothesis that "a non-Yugoslav, perhaps a Russian or a Pole" assumed Tito's identity was included. The report also notes Draza Mihailovic's impressions of Tito's Russian origins.
