Not much information exists for the general public about Jean Marembert. He is featured in the book Modern Figurative Painting: The Paris Connection.

From the book description:

The first half of the 19th Century spawned one of the most exciting concentrations of artists and artistic innovation in history. The French impressionists opened the door to creative freedoms never before experienced, and a community rich in artistic and intellectual talent coalesced to forever change the direction of art.

Here are a few of Marembert’s illustrations for Petrus Borel’s Le Lycanthrope, which I especially love:

He seems slightly ahead of his time with these macabre collage illustrations.

Horror novels, comics, graphic novels and other forms of illustration in this style began to develop in the mid 20th century…though I don’t recall ever seeing anyone cite Marambert as an influence.
