Ellen Key was a Swedish author and educator. She was very committed to feminism and fought hard for women's rights in the late 19th and early 20th centuries.
Her ideological basis is individualism, empirism and humanism. She won both great admiration and received sharp criticism. Criticism was based on her dismissal of Christianity, which was considered moral dissolution, her struggle for women's rights, her so-called. "antipatriotic" attitude in peace issues and what was considered to be a legitimacy of eugenics. But she can be considered to have contributed to the fact that society increasingly put the childrens interests best. Key exercised great influence on the school system, because she was influenced by Rousseau she rejected authoritarian education and segregated teaching.
