The Black Family in Slavery and Freedom, 1750-1925 is a book by Herbert G. Gutman that addresses the impact of slavery on black families. It is based on research that Gutman conducted over the course of the decade since the Moynihan Report, which revived the "tangle of pathology" thesis; the claim that black families in the US were incapable of functioning in a healthy way, a rationale previously rejected by critics as racist. The book draws on census data, diaries, family records, bills of sale and other records.
