[4] Her 1897 thesis, On the Electrical Resistance of Thin Films, showed that very thin metal films showed a higher resistivity than the bulk metal.

[5] Stone taught for a year at the Bryn Mawr School in Baltimore.

[7] From 1908 to 1914, she and her sister Harriet Stone ran a school for American girls in Rome,[1] and later in life they ran another school for girls in Washington, D.C.[8] Stone was one of two women (out of a total of 836) to attend the first International Congress of Physics in Paris (the other being Marie Curie).

[4] In 1899, she was one of forty physicists (and one of two women, the other being Marcia Keith) at the first meeting of the American Physical Society, held at Columbia University.

[9] Stone's research focused on the electrical resistance and other properties of thin films.
