Julius Wagner-Jauregg, Austrian physician and neuroscientist, Nobel Prize laureate (born 1857)

Julius Wagner-Jauregg was an Austrian physician, who won the Nobel Prize in Physiology or Medicine in 1927, and is the first psychiatrist to have done so. His Nobel award was "for his discovery of the therapeutic value of malaria inoculation in the treatment of dementia paralytica".

The Nobel Prize in Physiology or Medicine is awarded yearly by the Nobel Assembly at the Karolinska Institute for outstanding discoveries in physiology or medicine. The Nobel Prize is not a single prize, but five separate prizes that, according to Alfred Nobel's 1895 will, are awarded "to those who, during the preceding year, have conferred the greatest benefit to humankind". Nobel Prizes are awarded in the fields of Physics, Medicine or Physiology, Chemistry, Literature, and Peace.
