Belgian expressionist painter best known as the designer of the "bold rooster" (French: coq hardi) adopted on 3 July 1913 as the symbol of the Walloon Movement and today the flag of Wallonia.
Paulus gained notability during the Walloon Art Exposition of Charleroi in 1911 and, in the interwar period, he held several exhibitions in Europe and in the United States. He was part of the Groupe Nervia, a Belgian artistic circle, the purpose of which was to foster Walloon art, along with Maurice Langaskens, Kurt Peiser, Armand Rassenfosse, Émile-Henry Tielemans and Louis Titz.
In 1951 he was ennobled as Baron Pierre Paulus de Châtelet. He died on 17 August 1959 at age 78 in Brussels.
