[7] That same year another American woman, Margaret Eliza Maltby, also earned her doctorate, but from the University of Göttingen.

[8] This achievement was quickly followed by Isabelle Stone, who earned a PhD in physics from the University of Chicago in 1897.

[9] Noyes spent most of her career at Lake Erie College, where she worked from 1886 to 1900 and taught mathematics, physics, and astronomy.
