Roger David Servais (born in 1942 in Liège, Belgium) is a Belgian painter, graphic artist, sculptor and designer.

As citizen of Belgium he was free to travel and he commuted between Brussels and Berlin, but he endured reprisals from the East German government.

From 1990 onwards he joined the painter and civil rights activist Bärbel Bohley in her quest to shed light upon oppression and instrumentalization of the arts in the GDR.

His paintings and drawings visualize complex religious, historic and autobiographic statements which are expressed in an indirect and subtle way and are partly encrypted.

Single letters play a significant role, hinting at the context rather than identifying it; the colours contribute to the painting's essential meaning, too.
