Nathaniel "Nat" Corwin prepares equipment for a chemical analysis of samples in WHOI's Bigelow
Laboratory, circa 1960. Nat was widely regarded for his painstaking
analyses of the nutrients in seawater. He retired from the Institution
in 1986 but still volunteers in the WHOI Archives,
assisting with the documentation of the Institution’s vast historic collections.
