Glynis Johns (October 5, 1923 - January 4, 2024) was a South African-born British actress, dancer, musician and singer. Born in Pretoria, South Africa, while her parents were on tour, she is best known for originating the role of Desiree Armfeldt in A Little Night Music on Broadway, for which she won a Tony Award, and for playing Winifred Banks in Walt Disney's musical motion picture Mary Poppins. In 2020, with the death of Olivia de Havilland, Johns became the oldest living Academy Award-nominee in any acting category.

In both roles, Johns sang songs written specifically for her, including "Send in the Clowns", composed by Stephen Sondheim, and "Sister Suffragette", written by the Sherman Brothers.
