Premise: Ruth Gentry (February 22, 1862 – October 18, 1917) was a pioneering American woman mathematician during the late 19th century and the beginning of the 20th century. She was the first native-born Indiana woman to acquire a PhD degree in mathematics, and most likely the first woman born in Indiana to receive a doctoral degree in any scientific discipline.
Hypothesis: Ruth opened the way for many women to acquire degrees in mathematics.
