In March 2015, photojournalist Robert Johnson traveled to Selma, Alabama and joined thousands of Americans at the foot of the Edmund Pettus Bridge to honor the sacrifice and bravery of the men and women who bled on that very pavement exactly 50 years ago.

Many of the original “foot soliders” and civil rights leaders walked arm in arm across the bridge with President Barack Obama. Among them was Congressman John Lewis, who helped organize the first march over the same historic bridge in 1965, and endured a tragic beating on what has now become known as “Bloody Sunday.”
