This is the first book-length study of the history of gerontology. It shows how old age became a 'problem' worth investigating and how a mulitidisciplinary orientation took shape.Gerontology did not emerge as a scientific field of inquiry in the United States until the twentieth century. By tracing intellectual networks and analyzing institutional patterns, this study shows how old age became a problem worth investigating.Gerontology did not emerge as a scientific field of inquiry in the United States until the twentieth century.

Gerontology remains a marginal intellectual enterprise, but its very strengths and weaknesses illuminate the politics of specialization and academic turf-fighting in U.S. higher education.Introduction; Two Precursors; Keywords; OLD AGE BECOMES A 'PROBLEM' WORTH INVESTIGATING SCIENTIFICALLY; 1.
