Nuorteva emigrated to the United States in 1911 and played a leading role in the sizable Finnish-language socialist movement in America.
His father, Claes Fredrik Nyberg, was a telegraph officer and his mother was the Russian Jewish-born Anna Aleksandrovna Saharova.
Nuorteva immigrated to the United States in 1911, where he instantly became a leading member of the Finnish Socialist Federation in America and one of its most prominent spokesmen.
He left for the East coast to edit the monthly magazine Säkeniä ("The Spark") and worked on the editorial staff of Raivaaja ("The Pioneer").
"[7] In 1920, Nuorteva left the United States by traveling first to Canada and then to England, where he was deported after 10 days to Soviet Russia, the destination that he requested, rather than a return to the US.
[6] Back in Soviet Russia, Nuorteva was made the head of the Anglo-American Division of the People's Commissariat of Foreign Affairs.
