Prosper-Alphonse Isaac (1858-1924) was born in a well-to-do family.  This gave him the means not only of leaving his native Calais to pursue a career as an artist in Paris, but also the means to acquire art.  Isaac was particularly drawn to Japanese arts, which he collected avidly.  Many of the objects he bought were eventually given to museums.  As a printmaker Isaac started drawing seascapes in drypoint, but eventually moved on to become one of only a handful of artists versed in color woodcut techniques in France.  His compositions, generally small in scale, are heavily influenced by the arts of Japan.  He printed small editions of these works.  Aside from this artistic activity, Isaac was also an active textile decorator.  Sadly most of this work today seems lost.
