The collection contains Ruth Silberberg’s records of her collaborative research with her husband, Martin Silberberg, on skeletal aging and growth, and the study of osteoarthritis. It also contains Ruth Silberberg’s work on the relation of diabetes and joint disease after Martin’s death in 1966. The two series include reprints of scientific articles authored or co-authored by Ruth Silberberg, 1961-1976, and her photomicrographs, 1959-[1975]. After the Silberbergs received training in electron microscopy in 1959, the electron micrographs became an important tool in Ruth and Martin’s joint research and important illustrations for their publications of the period.
