Arturo De Vecchi moved to Naples at a very young age. He studied law and was known for his elegant appearance. As a fencer, he trained at the Academy of Fencing Naples school. His best individual result was the seventh place with the sabre at Amsterdam in 1928. As they did at the 1932 Olympics the Italian team sabre, with De Vecchi as a member, took second place at both the 1930 and 1931 unofficial World Championships, trailing Hungary both years. De Vecchi later served as a judge and an official.
