Jean-Pierre Vigier was born September 11, 1976 in Notre Dame de Lourde, Manitoba. A free-agent signing by the Altanta Thrashers in March, 2000, Vigier is a graduate of Northern Michigan University where he played four seasons and was a CCHA Second Team All-Star and member of the All-Tournament Team in 1998-99.
At the end of his Senior year at Northern Michigan, Vigier joined the IHL's Orlando Solar Bears and spent parts of two seasons with the team before making his NHL debut with Atlanta in 2000-01. Vigier split the 2001-02 season between the Thrashers and their AHL affiliate in Chicago. In only his second full season as a professional, Vigier was part of a championship team, helping Chicago capture the Calder Cup title.
After three straight 20-goal, 40-point seasons, Vigier earned a permanent roster spot with the club in 2003-04. He competed in 70 games with the Thrashers that season and returned to the Chicago Wolves during the NHL lockout in 2004-05. When the league returned to action in 2005-06, Vigier competed in 41 games with the Thrashers but missed the remainder of his season due to a right knee injury. He returned in 2006-07 with the Thrashers to complete a full season before signing with Geneve-Servette of the Swiss League in the off-season.
