Much of the early psychological research on Black fathers and families employed a deficit lens, pathologizing Black fathers as absent and uninvolved contributors to their children's development. As a response, several Black psychologists articulated the need to move away from deficit-based approaches and employ strengths-based and adaptive frameworks to examine the social experiences of Black fathers and their contributions to child development. This transformative work was not only central to advancing research on Black fathers but also a cornerstone in the broader fathering literature. Though the list of foundational architects of Black fatherhood scholarship spans disciplines, we center this article around the contributions of eight Black psychologists-Drs. Phillip Bowman, Cleopatra Howard Caldwell, Anderson J. Franklin, Nancy Boyd-Franklin, Vivian Gadsden, Harriette Pipes McAdoo, John L. McAdoo, and Melvin Wilson. Their collective works and scientific contributions provided a critical lens and articulated a vision for research on Black fathers. In highlighting their contributions, we focus on six thematic areas: (a) conceptual and theoretical advancements, (b) research methods and designs that centered Black fathers, (c) description and contextualization, (d) children's development and well-being, (e) theory to practice and intervention, and (f) scientific cross-pollination and collaborative ethos. Last, we review and highlight research branches and extensions of these foundational roots. (PsycInfo Database Record (c) 2023 APA, all rights reserved).
