Jules Bordet, Belgian microbiologist and immunologist, Nobel Prize laureate (born 1870)

Jules Jean Baptiste Vincent Bordet was a Belgian immunologist and microbiologist. The bacterial genus Bordetella is named after him. The Nobel Prize in Physiology or Medicine was awarded to him in 1919 for his discoveries relating to immunity.

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.
