Stieglitz was sailing to Europe in 1907 and found the company of other first class passengers unbearable. One day as he was trying to avoid them, he walked to the end of his deck and looked down into the part of the ship which accommodated the poor passengers. He perceived the ordinary men and women as flashes of colour dotted in among the geometric shapes of 'iron machinery'. Moved and fascinated by this sight, he raced to his cabin and returned with his camera to take a picture that to him constituted a step in his 'own evolution' .
