## 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.
