Before the 1940s, the biology and medicine of aging existed mainly as a scattered set of observations within physiology, pathology, and clinical medicine rather than as an organized scientific field. In the United States, a small informal circle of scientists and physicians interested in the biology of aging began meeting under the name the Club for Research on Ageing during the 1930s. This group provided the nucleus for the Gerontological Society of America, which was formally incorporated in New York City in 1945 with the explicit purpose of promoting the scientific study of aging and encouraging the exchange of resulting knowledge among researchers, clinicians, and policymakers. The Society began holding regular scientific conferences the following year, in 1946, and in that same year launched the Journal of Gerontology, giving the nascent field its first dedicated peer-reviewed publication outlet and a mechanism for establishing shared standards of evidence. In parallel, the US federal government began building formal research infrastructure for aging science. In 1941, physiologist Nathan Wetherell Shock became the first chief of the newly created Unit on Gerontology within the Division of Physiology at the National Institute of Health. Shock went on to establish and lead what became the Gerontology Research Center, and he served as the driving force behind the Baltimore Longitudinal Study of Aging, a study that began enrolling volunteers in 1958 and has continuously tracked participants' physiological and cognitive changes over decades, making it one of the longest-running studies of human aging in the world. Shock also served as president of the Gerontological Society of America from 1960 to 1961, president of the International Association of Gerontology from 1969 to 1972, and editor-in-chief of the Journal of Gerontology, and he is widely referred to by historians of the field as the father of American gerontology for his role in institutionalizing aging research as a distinct scientific pursuit rather than a subordinate topic within general medicine. Outside the United States, parallel institutional efforts were underway; the International Association of Gerontology and Geriatrics was founded in 1950, reflecting a broader mid-twentieth-century movement across Europe, North America, and elsewhere to formalize aging research internationally rather than as a purely American enterprise. Through the 1950s, 1960s, and into the 1970s, the Gerontological Society of America worked alongside allied groups such as the American Geriatrics Society to advocate for dedicated federal research funding, a campaign that succeeded when the US Congress established the National Institute on Aging in 1974, giving the field a permanent, well-funded federal home within the National Institutes of Health. This sequence, an informal scientific club maturing into a professional society, a dedicated journal, a landmark longitudinal cohort study, and eventually a federal research institute, is generally treated by historians of science as the founding arc of gerontology as a recognized, institutionally supported scientific discipline, distinct from the far older, purely clinical practice of geriatric medicine focused on treating older patients.
