The Tale of Mr. Jeremy Fisher is a children's book, written and illustrated by Beatrix Potter. It was released by Frederick Warne & Co. in July 1906. Jeremy's origin lies in a letter she wrote to a child in 1893. She revised it in 1906, and moved its setting from the River Tay to the English Lake District. The tale reflects her love for the Lake District and her admiration for children's illustrator Randolph Caldecott.

Jeremy Fisher is a frog who lives in a "slippy-sloppy" house at the edge of a pond. One rainy day he collects worms for fishing, and sets off across the pond on his lily-pad boat. He plans to invite his friends for dinner if he catches more than five minnows. He encounters all sorts of setbacks to his goal, and escapes a large trout who tries to swallow him. He swims for shore, decides he will not go fishing again, and hops home.

Potter's tale pays homage to the leisurely summers her father and his companions passed sport fishing at rented country estates in Scotland. Following the tale's publication, a child fan wrote Potter suggesting Jeremy find a wife. Potter responded with a series of miniature letters on the theme as if from Jeremy and his pals. After Potter's death in 1943, licences were issued to various firms to produce the Potter characters. Jeremy and his friends were released as porcelain figurines, plush toys, and other merchandise.

Helen Beatrix Potter (28 July 1866 – 22 December 1943) was an English author, illustrator, natural scientist and conservationist best known for her imaginative children’s books featuring animals such as those in The Tale of Peter Rabbit which celebrated the British landscape and country life.

Born into a privileged Unitarian family, Potter, along with her younger brother, Walter Bertram (1872–1918), grew up with few friends outside her large extended family. Her parents were artistic, interested in nature and enjoyed the countryside. As children, Beatrix and Bertram had numerous small animals as pets which they observed closely and drew endlessly. Summer holidays were spent in Scotland and in the English Lake District where Beatrix developed a love of the natural world which was the subject of her painting from an early age.

She was educated by private governesses until she was eighteen. Her study of languages, literature, science and history was broad and she was an eager student. Her artistic talents were recognized early. Although she was provided with private art lessons, Potter preferred to develop her own style, particularly favoring watercolor. Along with her drawings of her animals, real and imagined, she illustrated insects, fossils, archeological artefacts, and fungi. In the 1890s her mycological illustrations and research on the reproduction of fungi spores generated interest from the scientific establishment. Following some success illustrating cards and booklets, Potter wrote and illustrated The Tale of Peter Rabbit publishing it first privately in 1901, and a year later as a small, three-color illustrated book with Frederick Warne & Co. She became unofficially engaged to her editor Norman Warne in 1905 despite the disapproval of her parents, but he died suddenly a month later, of leukemia.

With the proceeds from the books and a legacy from an aunt, Potter bought Hill Top Farm in Near Sawrey, a tiny village in the English Lake District near Ambleside in 1905. Over the next several decades, she purchased additional farms to preserve the unique hill country landscape.
