Penelope Delta (1871-1941) was undoubtedly the most famous Greek writer of juvenile literature. She implemented the educational character of juvenile literature through a robust ideological background and a dedicated aesthetic perspective. Her novels led many generations of Greek people into adulthood but were just as easily read by adults. She was a staunch supporter of the educational benefit of demoticism.
In the entirety of her work, Literature and History formed an ideological pillar in the development of the nation at the beginning of the 20th century. Her mental and psychological state was delicate and caused her much emotional distress and spells of depression, which were documented in her journals. She committed suicide in 1941, on the day the German army entered Athens.
