That same year she was among the first 3 women admitted to the Yale School of Medicine. Based on alphabetical order, Farnam is considered the first woman to be admitted. She graduated in 1920 with honors, won the Campbell Gold Prize for the highest rank in examinations, and was selected as commencement speaker.
