While at the State Institute of Technology, Martens became acquainted with
Vladimir Lenin and
Julius Martov. Soon he became a member of their illegal
Marxist group
League of Struggle for the Emancipation of the Working Class. As the Soviet Bureau's administrative head,
commercial attaché, and financial advisor, Julius Hammer, father of
Armand Hammer, was assigned to generate support for the Russian Soviet Government Bureau and funded the Bureau by
money laundering the proceeds from illegal sales of smuggled diamonds through his company Allied Drug. In June 1919, under pressure from the
Lusk Committee, the Bureau was searched by police. In response to charges by the
United States Department of Justice, Martens stated in Washington, D.C., on 10 January, 1920, that he had done nothing to justify being deported. “My activities in the United States have been entirely friendly and along commercial lines,” he said. After hearings in the
United States Senate and the
United States Department of Labor, Martens was finally deported to Soviet Russia in January 1921. ==Return to Russia==
