Ruby Hirose was a biochemist and bacteriologist who researched blood clotting, antitoxins and allergies.
The child of Japanese immigrants, she struggled with issues of racial identity and discrimination. She finished her doctorate in 1932.
Hirose suffered from hay fever, and worked to improve pollen extracts used to treat that allergy. The idea to treat the pollen with alum, a chemical compound, to increase its effectiveness came from her research in diphtheria prevention.
In 1940, she was among 10 women recognized by the American Chemical Society for their accomplishments. She later made major contributions to the development of vaccines against infantile paralysis.
