Longtime NHL defenseman Dennis Seidenberg was born July 18, 1981 in Schwenningen, West Germany. Seidenberg switched from forward to defense as a junior-aged player in Germany and was drafted by the Flyers in the sixth round (172nd overall) of the 2001 NHL Draft.
Seidenberg showed promise after joining Ken Hitchcock's Flyers in 2002-03 (posting a plus-eight rating and 13 points in 54 games). However, he hit some growing pains as a developing young player and was later set back by a broken leg.
Seidenberg was a key member of the Philadelphia Phantoms team that won the 2004-05 Calder Cup during the NHL lockout. Traded to the Phoenix Coyotes on January 20, 2006 in the deal that brought veteran center Petr Nedved to Philadelphia, Seidenberg went on to enjoy a lengthy NHL career, most successfully during his seven seasons with the Boston Bruins following stints in Phoenix and with the Carolina Hurricanes and Florida Panthers.
A three-time Olympian for Germany (2002, 2006, 2010), Seidenberg won the Stanley Cup in 2010-11 as a member of the Bruins. During the Flyers portion of his early NHL career, Seidenberg played in a total of 63 regular season games (four goals, 13 points, 22 penalty minutes, average 16:45 of ice time) and three playoff games.
