Between 1974 and 1976, while researching for his filme "S. Bernardo", Leon Hirszman shot three documentary shorts produced by the Brazilian Ministry of Education on the chores of the men who worked in the sugar cane fields in the town of Feira de Santana, in the cocoa fields of Itabuna, and in the efforts of building households in Chã Preta.
