Cordier was an eminent French geologist, who taught Triger his first lessons in geology, where he quickly took interest in the technical challenges of this industrial sector.

This plunged him deeply into his work: the production of gravel from dolomite rock, the construction of public fountains in Mamers and the detailed study of phreatic groundwater tables near Le Mans.

With the financial and administrative support of Emmanuel de Las Cases, five steel shaft linings were drilled by this invention, which was subsequently adapted and applied to dig foundations, bridges and many tunnels.

He saw in this new system "the precious advantage of a universal language that one would understand everywhere, without comments and which would easily help the geologists from all regions of the globe to communicate".
