ctress, singer. Born on January 19, 1954, in Los Angeles, California. No matter what other accomplishments she achieves during her career, Katey Sagal will always be associated with her role as the blunt, rough-around-the-edges mother Peg Bundy on the hit comedy Married... With Children. She came from a show business family—her parents worked as directors and producers in television and film and several of her siblings acted professionally.
A talented singer and actress, Katey Sagal landed a few television movie roles in the early 1970s before focusing on her music career. She worked mostly as a back-up singer, touring with the likes of Olivia Newton-John and Bette Midler. In the 1980s, Sagal returned to acting and landed a role on Mary, a sitcom starring Mary Tyler Moore, set in a Chicago newspaper office. On the short-lived series, she played Jo Tucker, a hard-boiled columnist. Sagal had better luck with her next series, Married... With Children.
Debuting in 1987, the series featured the extremely dysfunctional Bundy family. Katey Sagal played Peg Bundy, the antithesis of the average television housewife. Brassy and loud, she had no interested in housework or her obnoxious, often sexist husband Al (played by Ed O'Neill). The couple had two bickering teenagers Bud (David Faustino) and Kelly (Christina Applegate). This was no polite comedy of manners—the characters put each other down at nearly every turn and the show broke new ground in terms of raunchiness.
During the run of the show, Katey Sagal experienced a personal loss. Eight months pregnant, she lost her baby with boyfriend Jack White in 1991. Her character had been pregnant on the series as well; the show addressed the situation by making all of the episodes with Peg pregnant part of a dream.
After the series ended in 1997, Katey Sagal appeared in television movies and landed a few short-lived sitcom parts. She also branched out in a new direction, lending her voice to the character of Leela, an alien spaceship captain, in the Matt Groening animated series, Futurama. Debuting in 1999, the series lasted for 72 episodes.
Making a successful return to situation comedy in 2002, Katey Sagal starred in 8 Simple Rules for Dating My Teenage Daughter as Cate Hennessy, a mother of three and worlds away from her Peg Bundy character. Cate was caring and understanding with her three children and husband Paul, played by John Ritter. Part of the show's premise was that the parents were switching roles—Cate returned to work as a nurse while Paul, a sportswriter, worked at home and looked after their two now teenage daughters and son.
Tragedy struck the show when John Ritter died unexpectedly in 2003. Katey Sagal and the rest of the show's cast and crew were devastated by the loss. The network decided to continue with the series and incorporated Ritter's death into the show by having his character died. As the show's central character, Cate Hennessy mourned the loss of her husband, comforted her children, and tried to move forward with her life. Other family members played by David Spade and James Garner were brought in later. It ended in 2005.
