After the death of her father, sociologist and law professor Dorothy Roberts decided to sort through his boxes. What she found was an archive of notes related to his research on interracial marriage, which he saw as a means to dismantle white supremacy. Roberts’ new memoir The Mixed Marriage Project chronicles her confrontation with her father’s research – and her role in it; she herself was the product of her parents’ mixed marriage. In today’s episode, she speaks with NPR’s Michel Martin about this trove of interviews with interracial couples and Roberts’ questions about her own family history.
