Marjan Pengov fenced foil for Yugoslavia at the 1936 Berlin Olympics, competing in both the individual and team events. He later emigrated to the United States where he worked as an engineer in Boston. Pengov also served as an assistant fencing coach at Harvard in 1956, under Edo Marion, one of his Olympic teammates who was also an engineer. In the late 1950s the engineering company that Marion worked for closed down and he lost that job. The trail on Pengov ends around that time, although it is likely that he moved back to Yugoslavia, and he is buried in Ljubljana.
