Charles Laveran. Portrait of Charles Louis Alphonse Laveran (1845-1922), the French physician who discovered the parasites which cause malaria. Laveran was a military surgeon who served in Algeria during 1878-83. In 1880 he discovered that malaria victims had pigmented bodies in their blood. He concluded that these parasites, called Plasmodium, caused malaria. It took five years for Laveran's idea to gain acceptance. He also researched leishmaniasis (kala-azar) and trypanosomiasis (sleeping sickness). Laveran was awarded the 1907 Nobel Prize for Medicine and used the prize money to found a laboratory of tropical medicine at the Pasteur Institute, Paris, France.
