Allan Jay captured gold medals at the 1960 Olympic Games in Rome in both Individual and Team Epee. Four years earlier, he finished fourth in the Foil event at the Mexico Olympics.

No fencer in modern times has won two titles at the same World Championships or Olympic Games, but Jay nearly did. In 1959, he won the World Championships’ Individual Foil title, and tied for first place in the Individual Epee event. However, the English champion lost a barrage 4-5, and had to settle for a silver medal in Individual Epee. He was the first fencer to finish first and second in two weapons with electrical judging, and only fourth all-time.

At other World Championships competitions, Jay took the 1957 bronze in Individual Foil, and a bronze in Team Foil in 1955. He was a silver medalist in 1965 in Team Epee.

Jay fenced in both the foil and epee events at the 1950 and 1953 Maccabiah Games in Israel,, capturing six gold medals!
