In the early 50s, in the compagny's historical birthplace, doctors at the Saint-Etienne "Corps des Mines" called for measures to deal with Silicosis, a miners' disease that takes hold in the deepest airspaces of the lungs. DTF medical was thus responsible for designing the first French generators and aerosol nebulizers.
The two founding families have since then continued to develop and expand DTF medical for three generations.
