Théo De Joncker

Théo De Joncker (Brussels, 11 April 1894 - Asse, 12 July 1964) was a Belgian composer.

Théo De Joncker was a student of August de Boeck and Paul Gilson. For years he conducted the orchestra of the Belgian National Radio (NIR), but he also enjoyed a conducting career outside of Belgium. As a composer, he belonged to the Brussels group Les Synthétistes. This group was found by students of Paul Gilson as a way to celebrate their teacher’s 60th birthday and included Francis de Bourguignon, Théo De Joncker, Marcel Poot, Maurice Schoemaker, Jules Strens, René Bernier, and Robert Otlet.
