Canadian actor Tahmoh Penikett was born on May 20, 1975 in Whitehorse, Yukon. The son of former Yukon premier Tony Penikett, he is a graduate of the Victoria Motion Picture School and also studied at the Lyric School of Acting in Vancouver. He made his debut in the 1996 television movie Murder on the Iditarod Trail, but only started acting at the entry of the 21st century, when he appeared in numerous roles on television. Early television gigs included guest roles in Stargate SG-1, Dark Angel and The L Word, as well as roles in a number of films.
Penikett’s first regular television role was in the Canadian police drama Cold Squad. Premiered in 1998, he joined the show’s final season in 2004, as Corporal Ray Chase. The series was cancelled shortly after.
In 2003, Penikett started his involvement with the remake of the hit science fiction series Battlestar Galactica. The reimagined take on the 1970s show saw him play the role of Karl Agathon, an electronic countermeasures officer paired with Sharon Valerii (Grace Park). He first appeared in the miniseries, where he sacrificed his seat to be able to accommodate a doctor into his Raptor and, consequently, into safety. The writers originally planned to kill him off after the miniseries, but they, as well as the fans, applauded his performance, eventually giving him a slot in the resulting television series. Premiered in 2004, Penikett’s character unwittingly became part of a Cylon experiment to determine whether a viable Cylon/human hybrid child can be created.
Penikett’s next notable television role was in the acclaimed Canadian thriller series Whistler, where he appeared in four episodes in 2007 as Elias Noth. He also signed on to be part of the Joss Whedon drama series Dollhouse, where he plays FBI agent Adelle DeWitt, who becomes romantically obsessed with lead Echo (Eliza Dushku).
