He was born in San Fernando, Buenos Aires Province, in the bosom of a cosmopolitan family. His father, Elmo Schulz Riga, of Baltic German origin, was born in the Latvian city of Riga, at that time part of Imperial Russia. His mother, originally from Italy, was named Agustina Solari. He was educated in Buenos Aires, first as a musician, then as an architect (although he never completed his architectural studies). After working as a schoolteacher and holding a series of minor jobs in the municipal bureaucracy, on April 5, 1912, he set out on the ship "England Carrier", supposedly to work his passage to Hong Kong, but he disembarked in London and made his way to Turin. He returned to London to meet up with his mother and aunt, with whom he traveled to Paris, Turin (again), Genoa, and his mother's native Zoagli. Over the following few years, despite the onset of World War I, he would move among these cities, as well as Tours, Marseille, and Florence; towards the end of the war he served at the Argentine consulate in Milan.
