Henri Pierson [solved]

Hello,

Please can we add Henri Pierson to our list of Engravers.

Here the source.

And in bonus the picture but not sure about the copyright:

Hello,

I added Henri Pierson, but his record has very few information.

The cited source gives some information, but it's quite unclear, since it mentions only last names, whereas the portrait gallery show two people with last name Pierson: Henri Pierson and Alexande Pierson (page 759).
On page 527, it mentions “Pierson et Tisserand font également partie de ce contingent d’enfants de la Banque entrés à 14 ans en 1870 et en 1871, que l’on suppose fidèles et qu’Ermel souhaite s’attacher.” So I understand that Pierson was born in 1856.

There was a Dutch banker called Henri Daniel Pierson born in 1856, but the assumed nationality and the portraits don't really match.
