Imre Nagy began fencing in his native Hungary at the age of 12 and continued perfecting his talents after immigrating to Canada in 1957. Competing out of the Palestre Nationale fencing hall in Montreal, he won the Quebec Provincial B Sabre individual and team tournaments in 1968, the A Sabre and B epee individual events in 1969, and the team sabre competition in 1970, the same year that he was nominated as Quebec’s fencer of the year.
He continued his streak of top three finishes in major provincial and national tournaments throughout the 1970s, which culminated in his selection to Canada’s 1976 Olympic fencing delegation. He dueled in the team sabre event at the Games, but was eliminated in the opening round after the squad finished last in its pool. Nagy continued to fence until the 1980s, at which point he began serving as an international referee.
