Jacques Laudy was one of the original artists of Tintin magazine, together with Hergé and Edgar P. Jacobs. Born in Schaerbeek as the son of painter Jean Laudy, he studied fine arts Brussels in the early 1920s. During this period, he met his future colleagues Jacques van Melkebeke and Edgar P. Jacobs.
In 1940, Laudy made his first appearance in Bravo! magazine, illustrating covers and tales, and making comic series like 'Bimelabom et Chibiche' and 'Gust le Flibustier'. He also introduced Edgar Jacobs to Bravo! and so was part in this grandmaster's comics debut. Jacobs would later model Francis Blake from his comic series 'Blake et Mortimer' after Laudy. In addition, Laudy created 'Buonamico' in Grand Coeur, and contributed to ABC and Petit Monde.
In 1946, he was involved in the launch of the Belgian edition of the magazine Tintin. For the magazine's early issues, he illustrated stories like 'Les Quatre Fils Aymon' and 'Rob Roy' and in 1948, he started his series 'Hassan et Kadour' from scripts by Jacques van Melkebeke.
In 1952, Laudy interrupted this series to make 'David Balfour', a comic scripted by Yves Duval and based on the work of Robert Louis Stevenson, as well as a couple of short stories. Laudy was also present in Petits Belges with 'L'Histoire comique de Charles Quint et autres contes' (1953-58) and also new stories with 'Hassan et Kadour' (1960-62). In 1962, he quit comics to devote all his time to painting. In 1991, he was named Knight in the Ordre of Leopold, and then Baron, by King Baudoin I. In 1993, he published a book about Edgar P. Jacobs. Jacques Laudy died that same year.
