Even though he isn't as well known as Piel or Gandon or Decaris
in my opinion he was one of the best of the early French stamp
engravers, especially when one considers his portraitures.
He was also different in that he strictly worked on steel
engraved dies but none for typographic printing which many
French engravers of the 1930's did.
Here is his first issued stamp.
