Paul de Man was born to a family of artisans of nineteenth-century Belgium and by the time of his birth, his family was prominent among the new bourgeoisie in Antwerp. He was the son of Robert de Man, a manufacturer and Magdalena de Braey. His maternal great-grandfather was the noted Flemish poet Jan Van Beers, and the family spoke French at home. His uncle Henri de Man (Dutch: Hendrik) was a famous socialist theorist and politician, who became a Nazi-collaborator during World War II. He played an important part in the decisions made by De Man during the Nazi occupation of Belgium. Paul's father, Robert ("Bob") de Man, was a moderately successful businessman whose firm manufactured X-ray equipment. De Man's father and his mother, Madeleine, who were first cousins, married over the family's opposition. The marriage proved unhappy.
