A Nobel With No Doctorate Behind It

Tu Youyou received half of the 2015 Nobel Prize in Physiology or Medicine, the other half shared between William Campbell and Satoshi Omura for a separate antiparasitic discovery, avermectin. What made her half of the prize unusual within the institution awarding it had nothing to do with the chemistry. Tu held no doctorate. She had no medical degree. She had never studied or trained outside China. Every other living scientist honored with an unshared or half-shared Nobel in the sciences up to that point had, at minimum, a research doctorate from somewhere, usually with a postdoctoral stretch abroad built into the standard career path the prize tends to recognize. Tu's formal training stopped at a bachelor's degree in pharmaceutical sciences from Beijing Medical College in 1955, and her entire career was spent inside Chinese institutions, largely the Academy that would later be renamed the China Academy of Chinese Medical Sciences. None of this is a story about the prize lowering its bar. Isolating artemisinin required the same thing every Nobel-caliber discovery requires, a correct answer nobody else had gotten to first, arrived at through Tu's own diagnosis that a standard extraction method was destroying the very compound it was supposed to reveal, and confirmed through her team's own animal testing in 1971 and human clinical work that followed. What her prize does complicate is a quieter assumption built into how the modern sciences usually tell their own success stories, that the paths to a major discovery run through a fairly narrow set of institutions and credentials. Tu Youyou's did not.
