Sam Olij was a Dutch amateur boxer, who was the national heavyweight champion 1926-28. At the 1928 Olympics, he was defeated in the quarter-final by the eventual winner, Arturo Rodríguez of Argentina. In the same year, Olij joined the police force, and became a member of the Dutch Nazi movement. During the German occupation in World War II, he worked for the “Central Office for Jewish Emigration”, an agency for deporting Dutch Jews. For arresting 30 blind Jews, who were deported to Poland for forced labor, and other crimes against humanity, Olij was sentenced to death in 1947. The sentence was reduced to life imprisonment, and following a psychiatric examination, a further reduced sentence was proposed, and he was released in 1954, after nine years. His son Jan, also a Dutch boxing champion, voluntarily joined the ranks of the Waffen-SS and fought on the eastern front. After being wounded he returned to the Netherlands and became infamous as a member of the Green Police. After the war, he fled to Spain, and later to Argentina.
