journalist and novelist, considered to be one of the fathers of contemporary Portuguese social-realist (or Neorealist) fiction.

Ferreira de Castro drew widely on his nine years' residence in the Amazon jungles of Brazil (1911–19) to vividly depict the Portuguese emigrant experience and the relationships among rubber workers of various regions and social classes in the frontier setting of the Brazilian rain forest. Two novels—Emigrantes (1928; “Emigrants”) and A selva (1930; “The Jungle,” translated into more than a dozen languages)—launched Ferreira de Castro's literary career and offered an almost photographic portrayal of an exotic region and its human tensions and high drama. In later novels the author turned his attention to regional Portuguese themes from rural areas; typical of this period are Terra fria (1934; “Cold Land”), A lã e a neve (1947; “The Wool and the Snow”), and A curva da estrada (1950; “The Curve in the Road”).

Ferreira de Castro had a long career in journalism, and he considered his fiction writing to be an extension of documentary reporting. He prized the communication of local colour and human warmth and sought to be faithful to social realism. He founded newspapers in both Pará, Brazil, and Portugal and maintained close ties with both countries.
