Photographs often portray important people in unexpected ways. In 1951, most people considered Albert Einstein to be the most brilliant scientist in the world. His ideas were used to develop the atomic bomb, and they would soon help people learn how to travel in outer space.
But Albert was also a man who liked jokes and having fun. This side of Einstein comes through in Arthur Sasse's famous portrait photograph. Sasse took Einstein's photo at the Institute for Advanced Study in Princeton. Einstein was celebrating his birthday; when Sasse asked him to smile for a picture, he stuck his tongue out instead!
