Onelio Jorge Cardoso

Cardoso was born in Calabazar de Sagua, nearby Encrucijada, Cuba.

One of these was as a traveling salesman, a job that allowed him to get to know different places and people within Cuba that would serve as models for the setting and characters of several of his stories.

However, it was not until 1945 when he became known by winning the "Alfonso Hernández Catá" contest with a story entitled "Coalmen" (Los carboneros).

He was also a documentary screenwriter for the Cuban Institute of Cinematographic Art and Industry (ICAIC).

In 1961, he joined the executive department of the literary section of the Unión Nacional de Escritores y Artistas de Cuba (National Union of Writers and Artists of Cuba - UNEAC).
