H. A. Rey’s wordless stories, Zebrology and Flying Fishes, were a satirical jab at the Nazi Race Laws of 1935. While seemingly simplistic for juvenile readers, at the time they were considered sophisticated and for an adult audience. For a discussion of this see H. A. Rey – Satirist or Subversive?
Hans Augusto Reyersbach (September 16, 1898 – August 26, 1977) was a German-born American illustrator and author, known best for the Curious George series of children’s books he created with his wife, Margret Rey. Many of their books are still in print.
Rey and his wife were German Jews who fled France in 1940, literally hours before the Nazis occupied Paris. They eventually made their way to New York.
