In 1829, the Dutch professor J.M. Schrant, reprinted the "Verhandeling op het niet achten der moederlijke tael in de Nederlanden, door een Brusselschen advocaat", in defence of the linguistic politics of King William I of the Netherlands. After the Belgian Revolution in 1830), another publicist, Adolphe Levae, blamed Verlooy for having voted for the union of Belgium with France. The historians of the Flemish Movement discovered around the 1900s that Verlooy was a unique advocate of the Dutch language. P. Hamelius mentioned him in his "Histoire politique et littéraire du mouvement flamand" (completed in 1894) and P. Fredericq did the same in his "Schets eener geschiedenis der Vlaamsche beweging" (published in 1906).
