The discoverer of plasmodium was charles louis alphonse laveran, a Frenchman. 1880, when he was a surgeon in Algeria, he noticed that there was a microorganism in the red blood cells of malaria patients, and he firmly believed that this microorganism (plasmodium) was the pathogen that caused malaria. This is the first time that protozoa have been found to cause human diseases. For this reason, his discovery and other studies on the pathogenicity of protozoa won the 1907 Nobel Prize in Physiology or Medicine.

Sir ronald ross (1857- 1932), a British doctor, found plasmodium in the stomach of Anopheles mosquitoes during his service as a British military doctor in India from 65438 to 0897. He was awarded the 1902 Nobel Prize in Physiology or Medicine for discovering the transmission route of plasmodium. Italian zoologist Giovanni Battista Grassi discovered the only mosquito that can spread plasmodium.
