Jean-Pierre Gibrat is a French comics artist and writer noted for his graphic historical novels set during wartimes in France.
He gained the attention of American readers of European comics with the translated version of his 2002-2005 graphic novel, Flight of the Raven, set in Paris during the WWII occupation.
The book is beautiful, filled with lush evocations of Paris. Gibrat studied various locations in pen and watercolor before translating them into story backgrounds in his comics drawing style, which is also done in pen and watercolor. Gibrat is also noted for his appealing depictions of female characters, and his attention to the visual details of everyday life.
Flight of the Raven was preceded by a related story (but not a direct prequel) set in the same time period, The Reprive, and was followed with a three volume story, Mattéo. — also set against the backdrop of war, but further back in time, in this case WWI.
You can find a number of his books on Amazon, some translated into English, some in French and other language editions.
The Reprive and Flight of the Raven were published in multiple volumes in France (three and two volumes, respectively) but were combined into single titles in the English language versions. The three French volumes for Mattéo are apparently being translated individually; only one has been released so far, the second English language volume is due in November of 2019.
Though he is both the artist and writer for his current work, Gibrat’s history of comics art goes back further, through collaborations with Jackie Berroyer and other writers, and work in the French comics magazine Pilote.
As far as I can determine, Gibrat does not have an official website, so I’ll point you to what resources I can find. You can also just try a Google images search for “Jean-Pierre Gibrat“.
[Note: Some of Gibrat’s work is erotic in nature, particularly a graphic novel titled Pinocchia, and a search may turn up images that are NSFW.]
