Arthur Sasse was an American UPI photographer. In 1948, his pictures were exhibited at a show at the Bronx Zoo.
He is best known for his photo of Einstein sticking his tongue out. The photo was taken on 14 March 1951, after Einstein’s 72nd birthday celebration at The Princeton Club. He made the iconic shot, but the other photographers surrounding the car missed it. The appropriateness of the photo was heavily debated by Sasse’s editors before being published on International News Photos Network. It became one of the most popular photos ever taken of Einstein, who himself requested nine prints for his personal use.
