‘Einstein’s personality, for no clear reason, triggers outbursts of a kind of mass hysteria,’ wrote a puzzled German consul to his superiors in Berlin during Einstein’s visit to America in 1930. Wherever Einstein appeared, the consul observed ruefully, he attracted huge audiences who were not just enthusiastic but positively worshipful. Overwrought admirers crowded round him, wanting to kiss his hand, touch his clothes, or just gaze into his eyes.

Albert Einstein is set to be the focus of another biographical film, although this one is said to be a less flattering look at his life.
