[[Dunn]] was founded in [[1921]] and is between the fountain pen golden age producers, when every company was founded on the basis of some sort of the technical innovation. In [[Dunn]]'s case the invention was a pump filling system very similar to the [[stantuffo tuffante|one]] used by [[OMAS]] in the [[Lucens]] many years later. That allowed the company to obtain a good market share.
