Belgian garden designer and landscape architect, formerly President of the International Federation of Landscape Architects (IFLA) and Chair of the Committee on Historic Gardens. In his Grammaire des Jardins he wrote that "My trade is to create gardens. However my professional life was very diversified: I had to direct public plantations, to take part in World Fairs, to study town planning, to inquire into the problem of the parks, then to take an interest in historical gardens... In fact, they are there the multiple facets of the same trade.' He undertook work in Belgium and France. The Oxford Companion to Gardens describes his work as 'eclectic with a strong tendency toward the formal' (eg his design for Veyrier-du-Lac at Haute Savoie.
