Canadian author whose poetry, short stories, novels, memoirs, and translations are notable for their versatility and sophistication.

Glassco abandoned his studies at McGill University, Montreal, to join the expatriate community in Paris, an experience he chronicled in the celebrated Memoirs of Montparnasse (1970), published more than four decades after it was first begun. He earned acclaim for his first published work, the poem “Conan's Fig,” which appeared in the international quarterly transition in 1928. After contracting tuberculosis, he returned to Quebec in the early 1930s. He continued writing and served in various public posts, including mayor of the town of Foster (1952–54).

Whereas his poetry deals with the simplicity of rural life in the Eastern Townships region of Quebec, his prose, inspired by the Decadents of the 19th century, is heavy with irony and eroticism. He wrote Under the Hill (1959), the completion of an unfinished romance by Aubrey Beardsley (Beardsley, Aubrey); English Governess (1960; also published as Harriet Marwood, Governess), a parody of Victorian pornography; and The Fatal Woman (1974), a collection of three novellas that explore the dehumanization of sexual fantasies. His verse collections, elegant and classical, include The Deficit Made Flesh (1958), A Point of Sky (1964), and Selected Poems (1971).
