Hey, it's NPR's Book of the Day. I'm Andrew Limbong. There's no silver bullet to fix racism, no easy single switch that we can flip and then, aha. We live in a racially harmonious utopia. But one man thought there was, and that sole solution was interracial marriage. He was a white anthropologist named Robert Roberts, and he devoted his research to this goal. And while his daughter, Dorothy Roberts, was always aware of the broad strokes of her father's work, she wasn't aware exactly how devoted to his work he was and how his work actually involved her. She's got a new book out telling the story. It's titled the Mixed Marriage Project. She talks about it to NPR's Michelle Martin after the break.

Michelle Martin
It began with a few dozen boxes left behind after the death of her father.
Dorothy Roberts
I confronted them because they'd been in my basement for a decade already. And so I I wanted to see what was there.
Michelle Martin
That's MacArthur Genius Award winner Dorothy Roberts, an African American woman known for her scholarship around race, gender and the law. Her father, Robert Roberts, was a white anthropologist from Chicago who spent much of his life steeped in a research project.
Dorothy Roberts
He believed that black and white people marrying each other was the best path to dismantling white supremacy and what he called the racial caste system in Chicago and in the United States.
Michelle Martin
Dorothy Roberts new memoir is the Mixed Marriage Project, in which she chronicles the discovery of more than an unfinished manuscript. I started by asking her if she had a sense of what she would find when she finally dove into those boxes.
Dorothy Roberts
I knew there would just be a lot of research, but it was a complete shock to me to find out that there was 100 years of marriages in these interviews. But even more shocking was that I'd always thought that he got interested in interracial marriage, especially black white couples, when he met my black mother. So this really flipped my whole conception of their relationship. So the question for me was, why did he get interested in this topic, and did he get interested in my mother because of his obsession with Interracial marriage.
Michelle Martin
Did you feel a sense of, I don't know, is it. Is betrayal too strong of a word? I mean, did you feel in a way that you were part of his research?
Dorothy Roberts
Yeah, well, of course, that question then extended to me. So it was not just a question of how my mother fit into his research project, but also how I and my sisters fit into it. You know, there was this belief that children born to mixed race couples would have psychological, social, even biological problems because they didn't fit into one group or the other. And he wanted to disprove that. And so when I found out that he had started these interviews and gone on this mission prior to creating, you know, our family and then later discovering a file he kept on me, it did raise the question, well, am I part of his research experiment to prove that. That children like me would be well adjusted?
Michelle Martin
Sort of threaded through the book is your own inquiry, but it's also his notes from the interviews that he did with interracial couples. Would you talk about some of those interviews? Because some of them are kind of painful to read, you know, frankly.
Dorothy Roberts
Oh, yes.
Michelle Martin
Some of the attitudes that some of the partners had about each other.
Dorothy Roberts
I had so many feelings about these fascinating interviews. So there were stories of courage and deep love and commitment, but also many of these couples still held, in my opinion, very racist beliefs. For example, my father discovers a club called the Manassas Society where he'd hoped to find mixed race couples to interview. And he discovers that most of the couples consist of white women and black husbands. And when he inquires about what happened to the black women married to white men, one white wife says very bluntly, the Manassas Society women don't like colored women. And why don't they like colored women? Because they believe colored women have loose morals and they don't demand that white men marry them.
Michelle Martin
Professor Roberts, those are some really painful stories. But you also say in the book that there was a point at which you didn't want people to know that you had a white father. Can you say more about that?
Dorothy Roberts
Yeah, that's true. Something I regret now, especially after reading the file that my father had on me and thinking back on how much he contributed to my identity. But it happened when I was in college. I joined a group of black students who were very, very close to each other. Just a dazzling, brilliant group of students. And I didn't want them to know that I had a white father. I thought that somehow that might interfere with my connection to them. I now feel that it probably wouldn't have made a difference, but I didn't want to take that risk. And I thought a lot about that in writing my memoir. Just memories of how close we were, how much he respected my opinion and then accepted when I disagreed with him. And so I did come to realize how important his lessons about human equality, the way he was so dedicated to his research, his mission to challenge the racial caste system. You know, all of those lessons and my upbringing carried with me to this day.
Michelle Martin
You've had a very distinguished career in the academy. You've written seminal works like Killing the Black Body, which many people may know. So how did this deep dive into your parents lives cause you to reflect on your own work?
Dorothy Roberts
I still don't believe that interracial intimacy is by itself is the answer. But I do think that we have to start with ourselves in our most intimate relationships when we think about how we are going to create a world that a future in which racial hierarchy is unimaginable. And I also came to realize that when, even though my work prior to this didn't touch on interracial intimacy or interracial love, that the deeper questions that my father was asking, they are questions that I've asked throughout my work as well. I think underlying it is the question of what will it take to love each other as equal human beings?
Michelle Martin
