Art Prud’homme joined the Princess Patricia’s Canadian Light Infantry of the Royal Canadian Army in 1916 and took up boxing two years later, while serving abroad during World War I. Upon his return to Canada, he gained attention on the amateur boxing scene as a rising star and was selected to represent Canada in the middleweight division at the 1920 Summer Olympics. At the Games he had little trouble with his early-round opponents, knocking-out Belgium’s Antoine Masson, France’s Marcel Rey-Golliet, and Norway’s Hjalmar Strømme before losing to Britain’s Harry Mallin in the final and settling for silver. In the same event, his countryman Moe Herscovitch won bronze. Prud’homme continued to box as an amateur until 1922, when a dearth of challengers led him to turn professional. In his first few years as a professional, he lost only to Herscovitch, and soon began competing under the pseudonym “Arthur Bryan”. He continued to box until his retirement in the 1930s.
