At 100, I have a mind that is superior - thanks to experience - than when I was 20.

At 20, I realized that I could not possibly adjust to a feminine role as conceived by my father and asked him permission to engage in a professional career. In eight months I filled my gaps in Latin, Greek and mathematics, graduated from high school, and entered medical school in Turin.

Babies did not attract me, and I was altogether without the maternal sense so highly developed in small and adolescent girls.

After a short period spent in Brussels as a guest of a neurological institute, I returned to Turin on the verge of the invasion of Belgium by the German army, Spring 1940, to join my family. The two alternatives left then to us were either to emigrate to the United States, or to pursue some activity that needed neither support nor connection with the outside Aryan world where we lived. My family chose this second alternative. I then decided to build a small research unit at home and installed it in my bedroom.
