Hayhurst served as principal of the
Friends' School in Philadelphia from 1857 to 1867, and for a time operated her own school, which was attended by many of her former students. In 1876, Hayhurst became the head of the pharmaceutical department at the
Woman's Hospital of Philadelphia. To broaden her knowledge of the subject, she began attending lectures at the
Philadelphia College of Pharmacy. Though Dr.
Clara Marshall had previously done so, it was rare for the college to admit women, and Hayhurst was the only woman in her class of 150. The college administration did not offer any resistance, however, and granted her a diploma in pharmacy when she completed her courses in 1883, at age 63. Hayhurst remained in her post at the pharmaceutical department of the Woman's Hospital for 33 years. She supervised the purchase and manufacture of supplies, assisted missionaries to foreign countries, and acted as mentor to 65 women pharmacists. She was a member of organizations such as the
New Century Club,
New Century Guild,
American Academy of Political and Social Science, and Woman's Suffrage Society of Philadelphia. Susan Hayhurst died in Philadelphia on August 7, 1909, after an illness of four days. The Philadelphia College of Pharmacy held a memorial service in her honor on November 15, 1910, and commissioned a painting of her to be hung in its museum. ==See also==
