Slavery is history. All the slaves and slave-owners are dead

In 1963, photographer Richard Avedon took a picture of a man named William Casby.
Casby was born in 1857 and was 106 years old at the time.
In his hands, he held his great-great-granddaughter, Cherri Stamps McCray.

The photo is remarkable because this elderly man, born into slavery more than a century earlier, is holding his descendant so gently.

William Casby lived until 1970, reaching the age of 113.
Many of his great and great-great-grandchildren are still alive today and remember him.

It shows how recently slavery existed. Even though it feels far away now, in modern America, some people still have memories of talking to those who were once enslaved.
