Actress Anne Schedeen, who gained widespread recognition for her role as Kate Tanner, the matriarch in the beloved 1980s sitcom "ALF," has died at the age of 77.

Schedeen portrayed Kate Tanner, a suburban mother navigating life with a wisecracking alien living in her garage, for the show's four-season run from 1986 to 1990. The character was a central figure in the popular NBC series, providing a grounded counterpoint to the chaotic presence of the ALF character.

Born in Oakland, California, Schedeen began her acting career in the late 1970s with appearances in television shows such as "CHiPs" and "Family." Her role on "ALF" became her most defining, earning her a place in the memories of a generation of television viewers.

Following the conclusion of "ALF," Schedeen continued to work in television, with guest spots on shows like "Murder, She Wrote" and "Star Trek: Voyager." She also lent her voice to animated projects, including "Invasion America."

Details surrounding Schedeen's passing have not been widely released, but her death was confirmed by sources close to the actress. The news has prompted an outpouring of tributes from fans and colleagues who remember her for her memorable performance on "ALF."

"ALF" centered on the Tanner family's efforts to hide their extraterrestrial houseguest, a furry, sarcastic alien named Gordon Shumway, or "ALF." The show was a significant ratings success for NBC during its original broadcast and has since found a lasting legacy in syndication and streaming platforms.

Schedeen's portrayal of Kate Tanner was characterized by a blend of warmth, humor, and exasperation as she dealt with the often-unpredictable situations brought on by ALF. Her character's interactions with the alien, as well as her family, were a cornerstone of the show's comedic appeal and emotional core.

Fans often recall Schedeen's ability to balance the absurdity of the premise with relatable family dynamics, making "ALF" a comfort viewing staple for many. Her career, though marked by this iconic role, also showcased her versatility in various television and voice-acting projects.
