Author Philip Dray is the author of the book, At the Hands of Persons Unknown: The Lynching of Black America. Dray chronicles lynching. He looks at the perpetrators, the groups and individuals who courageously took a stand against it (the NAACP, Ida Wells, and W.E.B. Du Bois) and the legacy it left behind. Dray researched his book at the Tuskegee Institute where records about lynchings have been kept from 1882. He is also the co-author of We Are not Afraid: The Story of Goodman, Schwerner, and Chaney and the Civil Rights Campaign for Mississippi.
