Hernán Díaz Arrieta (1891–1984), widely known by his pen name, Alone, was a Chilean writer, film critic and memoirist.
In a career spanning more than sixty years, Alone wrote for a wide array of newspapers and periodicals, penning, most notably, the column Crónica Literaria, which first appeared in La Nación and later in El Mercurio.
Several writers profited from his active promotion of their work, especially María Luisa Bombal and the poet Gabriela Mistral.
Despite his vehement opposition to Communism, he nevertheless was an outspoken admirer of the poet and Pablo Neruda who was a prominent member of the Communist Party of Chile.
He was a staunch catholic and supporter of the right-wing political movement that culminated in the 1973 overthrow of the leftist President of Chile, Salvador Allende.
