In 1921 Anna Maria, Levi's sister, was born; he remained close to her all her life. In 1925 he entered the primary school in Turin. A thin and delicate child, he was shy and considered himself ugly; he excelled academically. His school record includes long periods of absence during which he was tutored at home, at first by Emilia Glauda and then by Marisa Zini, daughter of philosopher Zino Zini. The children spent summers with their mother in the Waldensian valleys southwest of Turin, where Rina rented a farmhouse. His father remained in the city, partly because of his dislike of the rural life, but also because of his infidelities.
