Tedde Moore, an actress who is best known as playing young Ralphie Parker’s teacher in A Christmas Story, has died. She was 79.

Moore died Wednesday in Huntsville, Ontario, according to a post on her Facebook page. A cause of death was not given.

“On Wednesday August 5th under sunny skies overlooking Fairy Lake, Tedde passed away surrounded by family physically and spiritually in her beloved Huntsville Muskoka,” the post reads. “Her bravery in this choice was almost overwhelming, beyond beautiful and also difficult. Forever the teacher, she had a quote for every occasion and a special way of touching the lives and hearts of everyone she met. Her magic and love will be remembered by all she took under her generous and welcoming wings.”

Moore played Miss Shields in the 1983 Christmas classic opposite Peter Billingsley. She memorably gives Ralphie a bad grade on his paper about wanting the Red Ryder BB gun for Christmas and also has to deal with Flick (Scott Schwartz)’s getting his tongue stuck on a ice-cold flagpole. Moore was nominated for a Genie Award, presented by the Academy of Canadian Cinema and Television, for best performance by an actress in a supporting role. She reprised her role for 1994’s My Summer Story, which, like A Christmas Story, was based on Jean Shepherd’s semi-autobiographical stories.

Her other TV appearances include spots on Friday the 13th: The Series, RoboCop: Prime Directives, Odyssey 5 and This Is Wonderland. 

Moore played Mrs. Claus in the 2011 TV movie Mistletoe Over Manhattan and also portrayed Nanny Shaw in the miniseries The Kennedys that same year. According to iMDB.com, her final credit was the 2017 TV movie Magical Christmas Ornaments.

Born April 11, 1947, Moore was the daughter of Darwina Faessler Moore and actor Mavor Moore, best known for playing the title role in a Canadian radio drama adaptation of Nero Wolfe in 1982. Her grandmother was Canadian theater pioneer Dora Mavor Moore.

She attended the Royal Academy of Dramatic Art in London, graduating in 1967 with the Principal’s Medal of Honor. After graduating, she starred opposite Christopher Walken in the Stratford Festival production of A Midsummer Night’s Dream.

In 2009, Moore was diagnosed with multiple sclerosis.

Moore had two children with Canadian film and television director Donald Shebib, who directed many documentaries, including 1970’sGoin’ Down the Road and 1973’s Between Friends. Their children are daughter Suzanna, a child actor (Are You Afraid of the Dark?) turned teacher, and Noah, a child actor (Goosebumps) turned Grammy-winning music producer, also known as “40,” who is a frequent collaborator of Drake’s. 40, who produced the Drake hits “Hold On, We’re Going Home,” “One Dance,” “God’s Plan,” “Toosie Slide” and “Take Care,” was diagnosed with multiple sclerosis in 2007, two years before his mother.

Moore has another daughter, Zoë, from a previous relationship with actor Patrick Christopher Carter, and raised a foster daughter, Chaunce Drury.
