She grew up isolated from other children. She rarely saw her brother, who was sent to boarding school, while Beatrix was educated at home, by governesses.
Although she was quite shy, she was a very creative girl, encouraged by her parents and governesses who taught her to paint and draw. Beatrix had numerous pets and, through her holidays, spent in Scotland and the Lake District, developed a love of landscape, flora and fauna, all of which she closely observed and painted. Her London home she later described as "my unloved birthplace".
Her parents discouraged her intellectual development as a young woman, but her study and watercolours of fungi earned her respect among biologists of the period. Beatrix even wrote a scientific paper, but was not allowed to present it to the Royal Botanic Gardens at Kew, because of her gender.
In 1902, at the age of 36, Beatrix Potter published The Tale of Peter Rabbit, and became secretly engaged to her publisher Norman Warne. This caused a breach with her parents, who disapproved of her marrying someone they believed was of lower social status. Warne died before the wedding could take place.
The success of her children's books allowed her to become financially independent of her parents.She purchased a farm, Hill Top, near Sawry in England's Lake District. Over time, she extended her land holdings.
In her forties, she married William Heelis, a local solicitor. Beatrix published a total of 23 books, all in a small format designed for children's hands. Over time, as her failing eyesight prevented her from writing, her endeavours concentrated on sheep breeding and farming at Hill Top.
Beatrix Potter died on 22 December 1943, at the age of 77, at Castle Cottage in the village of Sawrey. She left almost all of her property to her husband who, after his death in 1945, left it to The National Trust to preserve the beauty of the Lake District.
