Malaria has been in existence since ancient times and for millennia thought to be carried by vapors. Alphonse Laveran made the discovery of the malarial parasite in 1880. The next most important milestone in the history of malaria was the unraveling of the mystery of malaria transmission. Ronald Ross, born in British India and educated as a doctor in England, was working in the Indian Medical Service when he discovered the transmission of malarial parasites by mosquitoes in 1897. The next year, he completed the life cycle of malarial parasites in birds. In celebration of the centennial year of that epic discovery, we reminisce on that event, focusing on the discoverer.
