The Cluysenaar is a Belgian family notably of architects and artists.
The roots of this Catholic family are in FlirschinTyrol, Austria. Some famous people descend from the original branch, among them Erich Klausener who was killed in the Night of the Long Knives.
The Belgian branch of the family descends from Paulus Klausener, whose son Johannes-Petrus was an architect.[1]
Joannes, an engineer in the Netherlands, was married to Gerinda Geritsen. They are the parents of Jean-Pierre.
