Eileen Soper was born in 1905 in the Municipal Borough of Enfield[1] and moved to the house where she was to spend the rest of her life in Harmer Green, Welwyn in the Hertfordshire countryside in 1908.
The house she later named "Wildings" was built by her father, the artist George Soper (illustrator) .
Today Soper is best known for her collaboration with Enid Blyton, most notably all of the Famous Five books.
Soper and her sister Eva lived in Wildings until they fell ill at similar times, both dying in 1990.
