His father was Arthur Warocqué, (1835–80),[1] a promoter of Belgian horticulture, after whom the arum Anthurium warocqueanum was named.

At the Universite Libre de Bruxelles (ULB), he participated in the Jeune Garde libérale (Young Liberal Guard).

Raoul Warocqué made the coal mines of Mariemont successful, and at 21 years of age had established a considerable fortune.

His most noted interventions relate to the Belgian Congo, military service, compulsory education and coal mining.

On his death in 1917, his art and antiquities collections were donated to the Belgian state and now form the basis for the Musée royal de Mariemont.
