His father was from Fuscaldo, and his mother was an Arbëreshë (Albanian minority in Italy) from San Martino di Finita.

[7] In 1929 he started college, attending the School of Physics and Mathematics at the Universidad Nacional de La Plata.

He was an active member in the Reforma Universitaria movement,[8] founding "Insurrexit Group" in 1933 – of communist ideals – together with Héctor P. Agosti, Ángel Hurtado de Mendoza and Paulino González Alberdi, among others.

[10] While attending a lecture about Marxism he met Matilde Kusminsky Richter, aged 17, who would leave her parents' house to live with Sabato.

[12] Before arriving at Moscow, he traveled to Brussels as a delegate from the Communist Party of Argentina at the "Congress against Fascism and the War".

While in France he made contact with the surrealist movement, studying the works of Oscar Domínguez, Benjamin Péret, Roberto Matta Echaurren and Esteban Francés among others.

[13] During that time of antagonisms, I buried myself with electrometers and graduated cylinders during the morning and spent the nights in bars, with the delirious surrealists.

At the Dome and in the Deux Magots, inebriated with those heralds of chaos and excess, we used to spend many hours creating exquisite cadavers.In 1939 he transferred to the Massachusetts Institute of Technology .

However, serving an obligation to those responsible for his fellowship Sabato started teaching at the Universidad de La Plata for Engineering admission, and relativity and quantum mechanics for post graduate degrees.

In 1945, his first book, Uno y el Universo, a series of essays criticizing the apparent moral neutrality of science and warning about dehumanization processes in technological societies, was published; with time he would turn towards a libertarian and humanist standing.

That same year he was awarded a prize by the municipality of Buenos Aires for his book and the honor wand of the Sociedad Argentina de Escritores.

Framed in existentialism, it was met with enthusiastic reviews by Albert Camus, who had Gallimard publish a French translation.
