In 1970, when Timothy Tyson was ten years old, a black man named Henry â€śDickieâ€ť Marrow was murdered in Oxford, North Carolina, allegedly for making a sexual comment to a white woman. Despite the testimony of eyewitnesses, the killers, Robert and Larry Teelâ€”known to be Klansmenâ€”were acquitted by an all-white jury. Tysonâ€™s father, Vernon, a United Methodist minister, was one of two white people who attended Marrowâ€™s funeral and joined the funeral march to the cemetery. After pursuing degrees in African-American studies, Timothy Tyson wrote a book about events in Oxford. Blood Done Sign My Name (Three Rivers Press) combines history, moral passion and storytelling. Tyson teaches African-American studies at the University of Wisconsin. We spoke with him about his book and the civil rights era.
