Samuel Glusberg arrived in Buenos Aires in 1905 brought by his family, part of which settled in Chile, a country where Glusberg later lived for a few years. Initially he studied in asmall Israelite school and later ni a public school. At sixteen, Glusberg was a fervent reader of Tolstoy, Turgenev, Heinrich Heine, and the Sephardic-Jewish philosopher Baruch Spinoza. These last two would later inspire his pseudonym. He studied at the Normal School, where he became familiar with the work of musicians such as Bach, Beethoven, Händel, which led him to associate with the Wagnerian Association, and he was active in socialism. In 1919 he asked Leopoldo Lugones, an expelled from socialism who at that time was converting to nationalism, to support a student congress from his public function, which led to the birth, despite the difference in age and ideology, a friendship that they would preserve until death. Lugones took him to work with him at the National Library of Teachersand Glusberg later became its editor. With the financial help of his uncles who lived in Chile, in 1919 he began to edit the Cuadernos América, which reached 50 numbers. With the Babel seal he published national and foreign books and in 1921 he did so with a literary ma- gazine with the same name that was published for seven years and in which eminent writers ofthe mature and young generation collaborated such as Jorge Mañach, Juan Marinello Vidaurreta, Mariano Picón-Salas, Arturo Uslar Pietri, Augusto d'Halmar.
