Frank says he was most drawn to blacks: the bare-chested boy in the back of a convertible; the woman relaxing beside a field in sunny Carolina cotton country; the dignified men outside the funeral of a South Carolina undertaker, who uncannily bring to mind the day President Obama eulogized Clementa Pinckney. At first, the South was to him ‘‘very exotic — a life I knew nothing about.’’ Then, in November 1955, Frank was traversing the Arkansas side of the Mississippi River, ‘‘just whistling my song and driving on,’’ as he says, when a patrol car pulled him over outside McGehee. The policemen’s report noted that Frank needed a bath and that ‘‘subject talked with a foreign accent.’’ Also suspicious were the contents of the car: cameras, foreign liquor. Frank was on his way to photograph oil refineries in Louisiana. ‘‘Are you a Commie?’’ he was asked.
Ten weeks earlier, Emmett Till was murdered a hundred miles away. ‘‘In Arkansas,’’ Frank recalls, ‘‘the cops pulled me in. They locked me in a cell. I thought, Jesus Christ, nobody knows I’m here. They can do anything. They were primitive.’’ Across the room, Frank could see ‘‘a young black girl sitting there watching. Very wonderful face. You see in her eyes she’s thinking, What are they gonna do?’’ Because his camera had been confiscated, Frank considers the girl his missing ‘‘Americans’’ photograph. Around midnight a policeman told Frank he had 10 minutes to get across the river. ‘‘That trip I got to like black people so much more than white people.’’
Coming to America after growing up listening to tyranny on the radio, Frank had been foremost a grateful émigré, and early pictures suggested it. Now, through a lens, the country darkened, and Frank became, the photographer Eugene Richards says, ‘‘a loaded gun.’’ Four days later, in New Orleans, Frank photographed the line of faces looking through the trolley windows. Once he saw that girl in McGehee, he says, he knew what to look for.
