Born on 23 April 1955 at Vincennes. Spent three years on training in iron, copper and aluminum work. At the age of 24, directed a graphic arts company in Val de Marne.

However, Thierry Dehais lives for sculpture: he spends all his full time on his passion, stimulated by the twofold influence of Alberto Giacometti and Auguste-Jean Gaudin. Generally, his creations are small (between 20 and 30 cm in height) and might appear rudimentary at a first glance. In reality, some of them (the Woman, the Man) exude a sort of existential reality, while others (the Song, the Embrace, the Prone Man) clearly indicate their thematic sculpted purpose.

Thierry Dehais produces his own patinas in order to procure the exact highlights he demands, drawing on his experience in the world of the graphic arts.
