[2] Zber's career was quickly accelerating and he was becoming increasingly renowned as a young protégée, with his reputation spreading far and wide, when the Nazis invaded France in 1940.

Although his career was short-lived, Zber's artwork left an indelible mark that speaks to the life and conditions of early 20th-century Europe, with great historical relevance.

Although most of his creations were destroyed by the Nazis, 39 of his woodcuts (plates) were found after the liberation of Paris, and are now housed in the Safed Museum of the Printing Art in Israel.

In 2007, the Musée d'Art et d'Histoire du Judaïsme in Paris exhibited a collection of Zber's oil paintings that he completed while in the French internment camp Beaune-la-Rolande.

There, as a way of earning income, Zber worked during the day at a picture postcard factory, and took private drawing lessons during his free time at night.

Skoczylas was a Polish artist born in Warsaw, who won the bronze medal for his series of artwork in the Olympic Games art competitions.

In the same year, Zber created his own portfolio of artwork and presented himself to the well-known Jewish art critic, Chil Aronson.

A year after his debut in Warsaw, Zber displayed his engravings of Jewish figures from his hometown, Płock, at the Paris World's Fair in 1937.

He was praised by high-ranking Parisian critics, and graphic arts experts wrote admiringly of him as a masterly young artist with a genius for wood engraving.

Even under these conditions he continued to pursue his artwork, such that, a recent exhibition in the Musee d’Art et d’Histoire du Judaisme included portraits painted by Zber while he was imprisoned there.
