Enid Mary Blyton, known for her pseudonym Mary Pollock, was an English children's writer, celebrated for her contributions to children's literature in the twentieth century. Her works, which span a wide range of topics including education, natural history, fantasy, mystery, and biblical narratives, have sold more than 600 million copies worldwide and have been translated into ninety languages. Blyton is most fondly remembered for her series such as Noddy, Famous Five, Secret Seven, Five Find-Outers, and Malory Towers.

Blyton's first book, Child Whispers, a collection of poems, was published in 1922. She was known for her prolific writing, often producing up to fifty books a year. Despite rumors of employing ghost writers, Blyton maintained that her stories were her own, springing largely from her unconscious mind.

Her books, though immensely popular among children, faced criticism for their unchallenging nature and themes, particularly in the Noddy series, leading to bans by libraries and schools and a refusal by the BBC to broadcast her stories from the 1930s to the 1950s. Critics have labeled her works as elitist, sexist, racist, and xenophobic. Nevertheless, updated versions of her books continue to be popular.

Blyton's commitment to providing a strong moral framework for her readers was evident through the clubs she supported, encouraging fundraising for animal and pediatric charities. The story of her life was dramatized in the BBC television film Enid, featuring Helena Bonham Carter.
