The studio was active until the late 1970s, during which time they won several prestigious awards for their work, including the Grand Prix at the Milan Triennale in 1957 and the Prix de la Ville de Paris in 1963.
Their designs were often characterized by clean lines, simple geometric shapes and the use of natural materials such as wood, leather and linen. Their style was influenced by modernist movements such as Bauhaus and De Stijl, as well as by the work of other contemporary designers such as Charles and Ray Eames.
Gebroeders & Martin De Wit's creations are today considered classics of Belgian modern design, and are highly sought-after by collectors and design enthusiasts worldwide.
