Portrait painter. Born in Brussels, Belgium on Nov. 21, 1882. Jonniaux attended Académie des Beaux Arts in Brussels. After serving in the Belgian Army during WWI, he established studios in both London and Paris. In 1930 his portrait of the Queen and King of Belgium established him as the court painter to the Belgian throne. Escaping from Nazi occupied France in 1941, Jonniaux and his wife settled in San Francisco. He also maintained a studio in Washington, DC where he painted such notables as President Roosevelt and Bishop Fulton Sheen. Schooled in the grand academic manner, his palette was tonal and dark with subjects meticulously rendered. Locally, his works were handled by the Hoover Gallery and Gumps. His home in San Francisco was at 1155 Jones Street with a studio at 712 Bay Street. His portraits of prominent people are found in private collections and public buildings throughout the U.S., South America, and Europe.
