Charles Louis Alphonse Laveran

Charles Louis Alphonse Laveran (June 18, 1845 – May 18, 1922) (sometimes spelled Alfons or Alfonse) was a French physician.

In 1880, while working in the military hospital in Constantine, Algeria, he discovered that the cause of malaria is a protozoan, the first time that protozoa were shown to be a cause of disease. In 1901 he described the trypanosomes of the mal de calderas. For this work and later discoveries of protozoan diseases he was awarded the 1907 Nobel Prize for Physiology or Medicine.

Alphonse Laveran is interred in the Cimetière du Montparnasse in Paris.
