Anne Schedeen, the actress who starred as matriarch Kate Tanner on NBC’s ALF (1986-’90), has died. She was 77.

Deadline confirms the actress died after the family announced on Sunday that she “passed peacefully” with a heartfelt tribute posted on her Facebook. A cause of death was not immediately known.

“It is with the heaviest of hearts that we share Annie has passed peacefully,” the family wrote in the post. “She leaves behind an extraordinary legacy of creative energy, whip smart humor, delight in her family, adoration for little dogs, burning hatred for Trump, passion for second-hand thrifting, and love for a good story. We are bereft without her. We loved her so so much, as did all who met her.”

They continued, “She was a force. And it is unimaginable to think about life without her in it. But as she said, ‘I’m always with you.’ And she’s right. The memories, artwork, belly laughter, handmade jewelry, oil paintings, sculptures, costumes, and all around joie de vivre live on. Raise a margarita in her honor.”

The family asked that in lieu of flowers, donations be made to “one of Annie’s favorite causes,” Habitat for Humanity. “We all love you, Annie,” they added.

Schedeen’s longtime agent Tom Markley also confirmed the news to Deadline. “Annie meant the world to her family and this agency,” he said.
