Answer: Mary Whiton Calkins
Step-by-step explanation:
Mary Whiton Calkins is famous female psychologist who completed all of the requirements for a doctorate in psychology but was denied that degree because of her sex. Calkins completed her PhD in 1881 and was poised to become the third woman in the United States to obtain a PhD. However, due to the gender bias in education at the time, her professors felt that she was not qualified to receive the degree, despite her stellar performance and work ethic. Despite this setback, Calkins went on to have a highly successful career in psychology, becoming the first woman to be appointed a professor at Harvard University.
