Last month, Curious George—the lovable, adventurous monkey—celebrated his 75th anniversary. In 1939, the authors, Hans Augusto Rey and Margret Rey, fled Paris on self-assembled bicycles after the Nazi invasion of France, carrying George and his story on their backs. They traveled for months through Spain, Portugal, and Brazil, and finally settled in New York City, where they connected with a publisher at Houghton Mifflin.
