A musically gifted child, Rogister studied violin, viola, horn and composition at the Liège Conservatory.
[2] Rogister studied composition with Jean-Théodore Radoux, and viola with Désiré Heynberg (1831–1898) and Oscar Englebert.
He continued to study composition and play in chamber music ensembles including Cercle Ad Artem, the Chaumont Quartet, and Piano et Archets.
[1] In 1923, he left for the United States where he briefly led the viola section in the Philadelphia Symphony Orchestra under the direction of Leopold Stokowski.
[3] Rogister, like his composition teacher Radoux, composed largely in the neo-romantic style of César Franck, occasionally introducing his own modernistic Impressionistic sonorities.
