What did Elie metchnikoff discover?
One such luminary was Elie Metchnikoff, a Russian scientist who was the first to discover phagocytosis, a cell-mediated immune response to foreign matter. Prior to his findings, white blood cells, for example, were thought to take up bacteria not to fight disease, but to spread it.
How did metchnikoff discover phagocytosis?
Mechnikov adopted the French form of his name, Élie Metchnikoff, in the last twenty-five years of his life. Mechnikov discovered phagocytes, immune cells that protect organisms by ingesting foreign particles or microorganisms, by conducting experiments on starfish larvae.

Élie Metchnikoff. This work formed the basis of Metchnikoff’s cellular (phagocytic) theory of immunity (1892), a hypothesis that engendered much opposition, particularly from scientists who claimed that only body fluids and soluble substances in the blood (antibodies)—and not cells—destroyed invading microorganisms (the humoral theory of immunity).
