Dr. Baker was without a doubt the leading expert of the time on children's health. In 1916 the dean of the New York University Medical School asked her to lecture the students on the subject. She agreed, on one condition -that he allow her to enroll and attend classes. He refused; women weren't allowed at his college. So she told him to find someone else. But there wasn't anyone who knew as much as Baker did. He finally gave in, and because he allowed her to attend the college, he had to open the campus to other women as well. In 1917 she became the first woman to receive a doctorate in public health from the school.
