During the civil rights movement of the 1950s and 1960s, photographers captured images that changed history. Their pictures showed peaceful protesters being treated unfairly. People across America saw these images in newspapers and on television. Many were shocked by what they saw. Photographers like Ernest Withers and Moneta Sleet Jr. documented events that might otherwise have been forgotten. Withers photographed the Memphis sanitation workers on April 4, 1968. They marched with famous signs that read "I Am a Man." His images showed the dignity of ordinary people standing up for their rights. Sleet won a Pulitzer Prize for his photograph at the funeral of Martin Luther King Junior. He became the first African American to win the award for photography. These photographs were more than news. They were works of art that captured emotion, courage, and suffering in a single frame. A powerful photograph does not just show what happened. It makes the viewer feel what it was like to be there. The civil rights photographs helped change American public opinion because they brought distant events into people's living rooms. Before television and newspaper photography, most Americans never saw what was happening in other parts of the country. These images made it impossible to look away. They proved that art -- even the art of a single photograph -- can be a force for justice.
