Max Theiler working on yellow fever. In 1926, they disproved Hideyo Noguchi's hypothesis that yellow fever was caused by the bacterium "Leptospira icteroides." In 1928, the year after the disease was identified conclusively as a virus, they showed that the African and South American viruses are immunologically identical. (This followed Adrian Stokes' inducing yellow fever in rhesus macaques from India). In the course of this research, Theiler contracted yellow fever, but survived and developed immunity. In 1930, Theiler moved to the Rockefeller Foundation in New York, where he later became director of the Virus Laboratory. He was professor of epidemiology and public
Nobel Prize controversies Chen-Ning Yang—by providing him in 1956 with a possible test method for beta decay that worked successfully. Her book "Beta Decay" (1965) is still a sine qua non reference for nuclear physicists. Several Nobel Prizes were awarded for research related to the concepts of the boson, Bose–Einstein statistics and Bose–Einstein condensate—the latest being the 2001 Nobel Prize in Physics given for advancing the theory of Bose–Einstein condensates although Satyendra Nath Bose himself was not awarded the Nobel Prize. In his book "The Scientific Edge", physicist Jayant Narlikar observed: "SN Bose's work on particle statistics (c.1922), which clarified the behavior of
