Joseph Alexandre "Patsy" Séguin (May 2, 1887 – August 8, 1918) was a Canadian professional ice hockey player. He played two games with the Montreal Canadiens of the National Hockey Association in the inaugural 1910 season, and scored one goal for the club.[1] [2] He was killed in action while serving in World War I in the Battle of Amiens.[3]
Séguin was a small player in stature who liked to play rough and mix it up with his opponents on the ice.[4] In 1912 Edgar Dey of the Halifax Socials was fined $50 by Halifax magistrate's court in Nova Scotia for assaulting Séguin in a January 5 MPHL game.[5] Dey himself died the following month on February 13 from chest injuries thought to have stemmed partly from his tussle with Séguin.[6]
