The department was originally founded in 1925 as the Department of Family Life at
Cornell. Its founding occurred during a broader historical context in the
United States during the 1920s that saw improving and expanding the science of
child psychology and
child rearing as a national imperative. It was one of the first university departments established in the United States that focused on child development specifically within the context of the family. Funding from the
Laura Spelman Rockefeller Memorial, which was part of a mission by the
Rockefeller Foundation to promote social science research and improve
child welfare, provided the department with
resources to create a
laboratory nursery school in which
faculty and
students conducted
empirical research observing the behavior of children and parents. Because of its empirical focus on the home, the family, and children, which were considered women's activities during the time, faculty and students in the department were generally women. Given limited opportunities for programs of study for women during the first half the 20th century, the department offered a particular niche for women at Cornell and helped train a generation of educators, health care providers, and social workers. In 1945, the department was renamed the Department of Child Development and Family Relationships. Along with the name change came a change in direction for the department as its funding support shifted to government grants and its empirical studies shifted from the laboratory nursery school to surrounding communities. In 1998, the department dropped "Family Studies" from its name and became known just as the Department of Human Development. In part, this change reflected an increasing focus on development across the lifespan. Throughout this time, more male faculty joined the department and the number of male students increased. By 2018, the department had added foci in adolescence, emerging adulthood, adulthood, and aging to its early childhood development roots. Its study of contextual influences had expanded beyond the family to a variety of contexts, including peer groups, schools, neighborhoods, and workplaces, in part due to Bronfenbrenner's theoretical work. There were 25 professorial faculty and approximately 35 masters and doctoral students in residence spanning multiple disciplines and methodologies. ==Legacy and influence==
