Albert Woodfox endured 43 years in solitary confinement, believed to be more than any other inmate in the history of the United States. He was locked in a 6ft by 9ft cell for 23 hours a day. For the remaining hour he was permitted to walk around a fenced-in concrete yard while shackled. He was mocked, beaten and tear-gassed by guards who subjected him to invasive daily strip searches. To bring the smallest semblance of variety into his days, Woodfox alternated between eating breakfast standing up or sitting down.

“Let others dollar up their art. Mine was unpriceable. It was to be bestowed.”

Mary Ellen Mark's skill was “to be able to pull things from reality, to see what’s strange and real”. Her Seattle story focused on a group of teenagers, some as young as 13, who had run away from home and were surviving selling drugs or by selling themselves for sex. She stayed involved with them in different ways. She tried to adopt one 13-year-old girl, Tiny, a sex worker, to remove her from the place; when that did not succeed, Mark worked with her husband, film-maker Martin Bell, to make a documentary that drew attention to these children’s lives. She stayed in touch with Tiny and the other kids throughout her life.
