Frederick Warne & Co. is a British publisher founded in 1865. It is known for children's books, particularly those of Beatrix Potter, and for its Observer's Books.

The Tale of Peter Rabbit is a children's book written and illustrated by Beatrix Potter that follows mischievous and disobedient young Peter Rabbit as he gets into, and is chased around, the garden of Mr. McGregor. He escapes and returns home to his mother, who puts him to bed after offering him chamomile tea. The tale was written for five-year-old Noel Moore, the son of Potter's former governess, Annie Carter Moore, in 1893. It was revised and privately printed by Potter in 1901 after several publishers' rejections, but was printed in a trade edition by Frederick Warne & Co. in 1902. The book was a success, and multiple reprints were issued in the years immediately following its debut. It has been translated into 36 languages, and with 45 million copies sold it is one of the best-selling books in history.
