Career
He was one of the first professional players in ice hockey. Born in Ottawa, Canada, Duval played intermediate hockey for the Ottawa Aberdeens and Ottawa Atlantic Railway teams before joining the Ottawa Hockey Club in the 1899–1900 season. He played two further seasons for Ottawa, and was named captain prior to the 1902 season.
He then turned professional with the Pittsburgh Victorias of the Western Pennsylvania Hockey League (WPHL) in 1902-1903, before joining the Pittsburgh Pros of the International Professional Hockey League for 1904-1905.
Duval died due to alcoholism on June 7, 1905. Duval had been acting in an unusual manner in the weeks previous, and had been drinking heavily.
He was released by the team in February 1905 for being unable to stay in condition to play. A Pittsburg Press newspaper report at that time said that ""Peggy" when in condition can hold his end up with any of them, but the wine when it is red seems to have a fascination for him, hence his downfall." At the time of death, Duval was working for the Pennsylvania Railroad.
Duval had previously worked for the Canada Atlantic Railway in Ottawa.
