Max graduated in law at the Free University of Brussels, and entered the legal profession, besides doing journalistic work. When he was 25 years old, he was elected a province councillor for Brabant, and was elected a city councillor in 1903. After he had worked as a magistrate, he was appointed mayor of Brussels on 6 December 1909.
Under the German occupation of Brussels during the First World War, Max refused to cooperate with the occupying forces. As a result, he was arrested and held in captivity, first at Namur, and then at Glatz (Poland) and Goslar (Germany), until he escaped on 13 November 1918. Charles Lemonnier was acting mayor during his captivity. On his return to Brussels, he was greeted as a hero. In 1919, he was elected to the Belgian Chamber of Representatives, where he campaigned for universal adult suffrage, a goal not achieved until after his death.
