The Valagianni School was founded in 1929 by Stamatia Patrikiou-Valagianni (1895-1985), the first Greek high school principal to have been a woman, and Emmanuel Valagiannis (1886-1975), a pioneering educator. The school was strict, but provided a broad education, for the standards of its time. This purely bourgeois Institute, mixed kindergarten, six-grade mixed primary school, girls' high school, girls' general education school, girls' boarding school, also had foreign language and music classes. Dozens of Jewish schoolgirls and students attended the Elementary School of the Greek Educational Institute Valagianni from 1929 - 1930 until 1942 - 1943. "One morning Rosa did not come to school in the first hour," notes Rozina's best friend, Professor Maria Negreponti-Delivani. "I found her crying with rage during the break. I came on foot from the ghetto, she told me, because they do not let us get on the bus. And how can they tell who you are? I asked her with my childish naivety. Don’t you see the yellow star I’m wearing? :She answered me upset, and then she asked crying ...What's so different about me that I cannot get on the bus? ».
