Brazilian educator. His ideas developed from his experience teaching literacy to Brazil's peasants. His interactive methods, which encouraged students to question the teacher, often led to literacy in as little as 30 hours of instruction. In 1963 he was appointed director of the Brazilian National Literacy Program, but he was jailed following a military coup in 1964. He went into exile, returning in 1979 to help found the Workers Party. His seminal work was Pedagogy of the Oppressed (1970).
