In 1922, he published the highly acclaimed Demonstrations, his first collection of poetry. In 1924 he founded a group named Correspondence with Paul Nougé and Camille Goemans from which he was excommunicated the following year; however, they became close again thanks to common interest in surrealism. Yet he was not a strict surrealist, being more interested in the metaphysics of the dailiness. The same year he was excluded from the group, Lecomte published his second book of poetry entitled Applications. The work featured two illustrations from his friend René Magritte. Magritte's growing interest in Surrealism maybe have begun with Lecomte. The artist often recounted the moment Lecomte took him to view a reproduction of Giorgio de Chirico's The Song of Love as a moment when he uncontrollably wept.[1] Lecomte also inspired a number of Magritte's paintings and was portrayed in his "Souvenir de Voyage" ("In Memory of a Journey", 1955).
Between 1934 and 1945 he was a teacher at a secondary school. While he continued to write poetry, Lecomte focused on critical work and reviews of art, philosophy and poetry, writing for a variety of newspapers, including a weekly column in La Laterne. From 1958, he also worked as a counsellor for the Brussels´ Museum of Art.
In 2013, University of Maryland doctoral student K. A. Wisniewski began translating selected poems by Lecomte into English. These poems have appeared in the Chariton Review at Truman State University and basalt from the Eastern Oregon University.
