Personal life
Born in Barbacena, Minas Gerais, he arrived in the city of Rio de Janeiro to study preparatory courses for medicine; however, he preferred personal independence, so he chose to dedicate himself to public service.

He began studying Public Administration at the Brazilian School of Public and Business Administration and graduated in 1957. During this period, he participated intensely in the student movement, becoming editor of the student newspaper. He founded Política Operária (POLOP) with Moniz Bandeira and Theotônio dos Santos, a left-wing political organization against the guidelines of the Brazilian Communist Party.

He died from cancer in 1997 in Rio de Janeiro at the age of 65.
