Carolyn Ramsey, 93, was a pioneer, working in a biology lab at a time when the field was mostly male. “She was a very intelligent woman with an ability,” said Eden Eskin, the mother of Ramsey’s daughter-in-law. “She was very interested in nature and the natural world.” Ramsey was found shot in her Virginia Highland home on Nov. 27. Police believe a relative killed her, then turned the gun on himself.
