Hours before the Nazis marched into the city in June 1940, the Reys fled on bicycles carrying drawings for their children’s stories including one about a mischievous monkey, then named Fifi.
Not only did they save their animal characters, but the Reys themselves were saved by their illustrations when authorities found them in their belongings. This may explain why saving the day after a narrow escape became the premise of most of their Curious George stories.
