It is said that Rubião was obsessive about his work, revising it at every new edition, always changing a few details, such as characters' names.
He attended school in Conceição do Rio Verde, then studied law in Belo Horizonte, graduating in 1942.
The book won little acclaim and Rubião began work as a political advisor.
The publication of O pirotécnico Zacarias in 1974 brought Rubião sudden literary fame.
He is believed to have influenced many Brazilian authors, among them José J. Veiga and Moacyr Scliar.
