Sam Olij

Simon Paulus "Sam" Olij (5 October 1900 in Landsmeer – 4 August 1975 in Amsterdam) was a Dutch heavyweight boxer, who represented his native country at the 1928 Summer Olympics. There he was eliminated in the quarterfinals of the men's heavyweight division by eventual gold medalist Arturo Rodríguez from Argentina. Mr. Olij was also a member of the feared national socialist Nazi allied NSB party during the Second World War. As such he betrayed numerous Jewish people and had them arrested and deported by the Nazis. One of them was his Jewish Dutch boxing team member Ben Bril. As he arrested Ben Bril, he said, "Plicht is plicht." (Duty is duty.)
