Gilberto de Mello Freyre (March 15, 1900 – July 18, 1987) was a Brazilian sociologist, anthropologist, historian, writer, painter, journalist and congressman, born in Recife, Northeast Brazil.
His best-known work is a sociological treatise named Casa-Grande & Senzala (variously translated, but roughly The Main House and the Slave Quarters, as on a traditional plantation).
Two sequels followed, The Mansions & the Shanties: The Making of Modern Brazil and Order & Progress: Brazil from Monarchy to Republic.
The trilogy is generally considered a classic of modern cultural anthropology and social history, although it is not without its critics.
