The picture is of Alice Seeley Harris, the man's name is Nasla. Here is a part of his account (from the book "Don't Call Me Lady: The Journey of Lady Alice Seeley Harris"): he had not made up his rubber quota for that day, so the Belgian-appointed overseer had his daughter beheaded. . hands and feet. His name was Baoli. She was five years old. Then they killed him. But they were not finished. Then they also killed his wife.
And because he didn't seem ferocious enough, strong enough to stand his ground, they cannibalized both Bidli and her mother. And he presented Nasla with tokens, what was left of the once living body of his beloved child whom he loved dearly. His life was destroyed.
They partly destroyed him anyway by forcing his servitude but this act ended it for him. All this filth happened because a man, a man who lived thousands of miles across the ocean, a man who could not be rich enough, had decided that this land belonged to him and that these people would serve their greed.
