Malaria treatment for syphilis wins Nobel Prize.

Austrian psychiatrist Julius Wagner-Jauregg won the Nobel Prize in medicine in 1927 for treating late-stage syphilis by infecting patients with malaria. He hypothesized that the high fever would cure the syphilis, and he was right. Although many of his patients died, mostly of their syphilis but some of malaria, a quarter recovered. Late-stage syphilis of the brain was no longer a death sentence. Wagner-Jauregg's reputation was tarnished due to his support of the Nazi movement and eugenics research.
