After studying painting and art history, Joel Meyerowitz became a magazine art director but after observing a studio shoot, he had a revelation: ‘This photographer was moving around the room, snapping – click, click, click! – and he was cajoling the subjects – these two young girls – to keep moving, too. I was mesmerized. Robert Frank never said a word to me that day, but he affected me deeply. I walked out of there and I literally saw the world differently. Everywhere I looked, there was movement and there was color.’ Ignorant about photography and its techniques, Joel Meyerowitz established a personal almost melancholic style and decided, in the 1970s to solely use color: ‘The world was in color. It was just so obvious to me. I had no idea people were snobbish about color. To me, black and white just seemed back there, historical.’ The incarnation of the All-American photographer, he was the only one admitted on the World Trade Center site after the 9/11 attacks: quite a poignant symbol.
