Biochemist and bacteriologist Ruby Hirose researched serums and antitoxins at the William S. Merrell Laboratories. In 1940, Hirose was among ten women recognized by the American Chemical Society for accomplishments in chemistry, and later made major contributions to the development of vaccines against infantile paralysis. The original caption to this photograph read: "A hay fever sufferer herself, Dr. R. Hirose, American-born Japanese girl scientist on the research staff of the Wm. S. Merrell biological laboratories, has found a way to improve the pollen extracts used to 'desensitize' hay fever sufferers. ... The idea of treating the pollen with alum to increase its effectiveness developed while Dr. Hirose was working on alum-precipitated toxoid for protection against diphtheria.
