The Mixed Marriage Project

Dorothy Roberts, a law and sociology professor at the University of Pennsylvania, opened twenty-five cardboard boxes shipped from her deceased parents' home and discovered yellowed typewritten transcripts of interviews her father conducted with interracial couples in Chicago. Robert (Bob) Roberts, an anthropology professor, spent decades researching Black-white marriages, a project Dorothy had always assumed began after he met her Black Jamaican mother, Iris White, when Iris was his student at Roosevelt College. But the earliest interview was dated February 19, 1937, when Bob was only twenty-one. The discovery raised a troubling question: Did her father's academic obsession with interracial intimacy lead him to pursue an interracial marriage, rather than the other way around?

Dorothy rented an apartment near her childhood home in Chicago's Hyde Park-Kenwood neighborhood and spent a summer reading nearly five hundred interviews spanning from 1937 through the 1980s. She decided not to finish her father's unwritten book but instead to trace her parents' story through the intertwined accounts of the couples they met.

Bob was the son of a Welsh immigrant father and a second-generation German American mother, raised in a bilingual household. At sixteen, he traveled with his German great-grandmother, Dora Huch, to India and around the world, an experience Dorothy believed set him on the path toward anthropology. His brother Edward later disowned him for marrying a Black woman, sending a birthday card decades later confessing his inability to overcome the early associations that divided them, while their brother Alfred served as best man at the wedding.

As a graduate student at the University of Chicago in the 1930s, Bob joined a major sociological study of Black Chicago and began quietly interviewing Black-white couples on his own. The transcripts revealed the city's brutal racial geography—the Black Belt that confined Black residents to overcrowded neighborhoods, restrictive real estate covenants, police raids on interracial gatherings, and informal clubs like the Manasseh Society that catered almost exclusively to white women with Black husbands, excluding Black women married to white men. Bob attended communist political dances, visited nudist camps, and built a network of mixed couples that would later include the Black servicemen and their European war brides who returned to Chicago after World War II.

Iris White was born in Kingston, Jamaica, attended the prestigious Wolmer's High School for Girls, and spent years in Liberia—a journey connected to the Garvey movement through a family link Dorothy only later pieced together—before arriving at Roosevelt College on a scholarship. Bob fell in love with her in the summer of 1952 but waited until his disapproving mother died before proposing, a delay Iris considered cowardly. Dorothy discovered that Iris was not simply Bob's research assistant but a coinvestigator who recruited couples, conducted her own interviews, and wrote vivid field notes that Dorothy had never seen before. After their December 1954 wedding, performed by CORE cofounder Homer Jack, the couple continued the project together, hosting parties and introducing interracial couples across Chicago, building a social network as much as a scholarly archive.

Dorothy grew up in a grand Victorian house on Kenwood Avenue, where her father's perpetually unfinished book was a constant presence and her mother kept an immaculate home while quietly helping to conduct research for which she received no public credit. Bob signed contracts with Simon & Schuster and later G. P. Putnam's Sons but never delivered a manuscript, returning advances and watching deadlines pass. Shaped by the civil rights movement, Black Power, and years living at an international school in Cairo, Dorothy came to identify solely as Black—sometimes hiding her white father's identity from classmates at Yale and rejecting interracial marriage as a cure for racism.

Late in her summer of reading, Dorothy discovered that her father had kept a research file on her, labeled Research Participant No. 224, containing a college paper arguing that ethnicity was a matter of personal choice and an essay in which she had declared the white part of her parentage insignificant. The discovery forced her to reckon with the structural advantages her father's whiteness had quietly provided, with her long suppression of his influence on her identity, and with the central question she had spent her career circling: whether it is possible to love across the racial divide without being shaped by the hierarchies that define it. The memoir ends not with a definitive answer but with a reconciliation—with her father's memory, with the complexity of her own origins, and with a deepened understanding of the mixed marriage project that shaped who she is.
