Charles Emil Jacque (1813 - 1894)
According to available literature and reference Charles Jacque was probably to first to initiate the revival of etching and renewed interest in Rembrandt’s etchings. As a mainly self-taught artist he studied and copied the works kept and displayed in the Louvre. It is not impossible he met Louis Marvy here.
The example I found (not acquired) is showing all the claire-obscure characteristics of Rembrandt but is not an actual copy. It seems based on paintings by Rembrandt. Marvy went much further in actually copying Rembrandt plates in detail.
