Interesting biography of a little-known but seminal Walloon centre-right statesman. Duvieusart is one of the scarce right-wing-leaning Walloon nationalists, and was active in the Rassemblement Wallon. Quite remarkable, since he had been prime minister during the Royal Question (1950-1951), instrumentalised by his Christian-democratic party to gain an absolute majority, which had been lost after WWI. Duvieusart was a key figure in Postwar European Integration, as Minister for Economic Affairs. He presided the Parliamentary Assembly of the EEC, and showed devout admiration for Charles De Gaulle.
