Jacob Aaron Nosovitzky (or Nosovitsky; 21 May 1891 –) was a Ukrainian revolutionary who became a spy for the U.S Department of Justice – agent N-100 – in 1919. He came to play a significant role in the emergent Comintern activity in America and elsewhere.[1]
Nosovitzky was born in Poltava, now Ukraine, the son of Israel Nosovitzky. He was arrested for bigamy in 1926.[2]
Nosovitsky also became a major suspect in the Lindbergh kidnapping case during the 1930s.
