Banker; art collector. Renders was born as Émile-Léon Houvenaeghel. He was adopted by the Bruges antiquarian August-Adolf Renders, receiving the family name Houvenaeghel-Renders, abridged to Renders in 1907. He married Julienne Sylvie D'Hoore (1875-1956). From 1920 onwards, Renders unscrupulously purchased a considerable collection of early Flemish paintings. Throughout his career, he collaborated with the painter and restorer Joseph van der Veken (1872-1964).
