An interesting story of the life and work of a Spanish woman who ended her days exiled in Chile, because of her participation in the II Spanish Republic government. Educated in the Institution of Free Teaching, Matilde Huici participated actively in the feminist movements of her time and, as psycho pedagogue and lawyer, she played an extraordinary role in the Tribunal of Minors, created in Madrid for the defence and education of minors in marginalized situations due to incapacity or delinquency. Affiliated to the Socialist Party, it was not, however, her political militancy which gave her a place in women’s history, but her position as researcher and expert in Psycho Pedagogy, her educational contributions and, during her exile in Chile, the creation of the school of nursery teachers. Matilde Huici, “the third woman”, along with Clara Campoamor and Victoria Kent, was one of the most renowned lawyers of her time. The book is specially aimed to those interested in the History of Women in the XX century. The path of Huici opens fields for research on other topics; therefore this book will also be of interest to University Departments of Education and of Gender Studies
