The starting point
It all started when Hippolyte Dumont took over as head of the Ampsin quarry in 1889. Little did he know that his decision would give rise to a dynasty of industrialists who, from generation to generation, would nurture and develop their entrepreneurial spirit, perpetuating his legacy.
Although Hippolyte Dumont was still quite young, he already owned several brickworks in the Liege region. He was a capable man with a sense of organization and a spirit of conquest. It is this versatile, enterprising young man who founded the group that today bears the name of his son-in-law Leon Lhoist.
