Belgian poet, novelist, short-story writer, and essayist whose work reflects his experiences of foreign lands and cultures.

Thiry volunteered for service during World War I. Francophilic and pro-Walloon, he was elected to the Belgian Parliament in 1968 representing the Rassemblement Wallon party. He became lifelong secretary of the Belgian Academy in 1960. Often sad or ruminative, his poetry blends modernism and nostalgia. Toi qui pâlis au nom de Vancouver: Œuvres poétiques, 1924–1974 (1975; “You Who Pale at the Name of Vancouver: Poetic Works, 1924–1974”), which takes its title from Thiry's first volume of poetry, collects his poems of half a century. His fiction explores the theme of time as well as the problem of the artist in a bourgeois milieu. Échec au temps (1945; “Defeat in Time”) mixes the scientific-philosophical with the fantastic, as does Nouvelles du grand possible (1960; “Stories of Great Potential”), which contains two of his best stories, “Distances” and “Le Concerto pour Anne Queur.” As well as essays on war and politics, he contributed an influential study in conservative aesthetics, Le Poème et la langue (1967; “Poetry and Language”).
