Potter, (Helen) Beatrix (1866–1943)

English writer and illustrator of children's books. Her first book was The Tale of Peter Rabbit (1900), followed by The Tailor of Gloucester (1902), based on her observation of family pets and wildlife. Other books in the series include The Tale of Mrs Tiggy-Winkle (1904), The Tale of Jeremy Fisher (1906), and a sequel to Peter Rabbit, The Tale of the Flopsy Bunnies (1909). Her tales are told with a childlike wonder, devoid of sentimentality, and accompanied by delicate illustrations.

Potter was also an accomplished mycologist. She was the first person to report the symbiotic relationship between lichen and fungi, and to catalogue the fungi of the British Isles. She was excluded from professional scientific societies because of her sex.

She had a quiet and restrained childhood in London, relieved by holidays in Scotland, Wales, and the Lake District, during which she studied and painted the countryside and its animals and plants. Her first illustrated stories were sent with letters to the son of her former governess, and their popularity made her consider publishing them; the first two were printed privately, at her own expense. In 1903 Frederick Warne took over publication of her work and The Tale of Squirrel Nutkin (1903) was her first popular success.

From 1905 she lived in the Lake District, where she bred hill-sheep and was an active conservationist. In 1913 she married a solicitor, William Heelis. Her diaries, written in a secret code, were translated and published in 1966. She left her extensive estate to the National Trust, and her Lake District home at Sawrey is now a museum.
