He is best known as the co-author of the book They Poured Fire on Us From the Sky (2005), written with his brother Alephonsion Deng, cousin Benjamin Ajak, and Judy A. Bernstein.
When Benson was a seven-years-old member of the Dinka tribe, Sudanese National Islamic militants attacked his village of Juol, Sudan, and he fled with his brother and cousin at the age of five.
Promised that he would be arriving in a safe camp with education, he was disappointed to see that he was instead led to do manual labor, and fight for the rebel cause.
Today he runs the computer digital photography system at Waste Management Corporation in El Cajon, California.
Released on June 13, 2005, it was entitled: They Poured Fire on Us from the Sky: The True Story of Three Lost Boys from Sudan.
