The iconic image of Einstein on our cover was taken in 1947 by the legendary photographer Philippe Halsman. Einstein was not fond of photographers (he called them Lichtaffen, or light monkeys), but he had a soft spot for Halsman. Einstein had personally included the photographer on a list of German artists and scientists getting emergency U.S. visas to evade Nazi capture. Halsman recalled that Einstein ruminated painfully in his study on the legacy of E=mc2: talk of atomic war, an arms race. "So you don't believe that there will ever be peace?" Halsman asked as he released the shutter. Einstein's eyes, Halsman said, "had a look of immense sadness...a question and a reproach in them." He answered, "No. As long as there will be man, there will be war."
