Cartier-Bresson is regarded as one of the art world's most unassuming personalities. He disliked publicity and exhibited a ferocious shyness since his days of hiding from the Nazis during World War II. Although he took many famous portraits, his face was little known to the world at large. This, presumably, helped allow him to work on the street undisturbed. He denied that the term "art" applied to his photographs. Instead, he thought that they were merely his gut reactions to fleeting situations that he had happened upon.
