Ann T. Nelms

Ann T. Nelms (born 1929) is a prominent African American nuclear physicist. Her research, which involved the study of the persistence of nuclear radioactivity, was cited in reports on nuclear fallout and human health.

Life and career

Nelms was born in 1929^[1][2] in Waycross, Georgia.^[3]

She worked as a nuclear physicist for National Bureau of Standards in the 1950s.^[3] She collaborated in her nuclear research with Ugo Fano, an Italian-born academician who joined the National Bureau of Standards as the bureau's first theoretical physicist after a stint at Aberdeen Proving Grounds. She also collaborated with J W Cooper, a senior research fellow with the National Bureau of Standards.^[4]

As of January 1954, she lived in the Washington, D.C., area with her husband and one-year-old child.^[3]
