William Tarmey

William Cleworth-Piddington (born 4th April, 1941) is a British actor and singer who has achieved national iconic status for his portrayal of Jack Duckworth on Coronation Street, a role he has played from 1979 (continuously since 1983) to the present day. Prior to his casting as Jack, William had appeared on numerous Street episodes as a background extra, mainly in the Rovers Return Inn, and in December 1978 he played Jack Rowe.

William suffered a major heart attack in 1976, and has had infrequent health problems ever since, but this has not hindered his status as one of Corrie's longest-serving and most popular actors. In 2008 it was reported in the media that he would quit his 29-year role as Jack Duckworth (his screen wife Elizabeth Dawn had recently retired from the programme due to health problems), but Bill has refuted these claims and has vowed to carry on in the show until at least his 30th anniversary.

Bill's other television credits include Crown Court and Strangers. Also an accomplished singer, he has released several albums.
