The story of the word

Élie Metchnikoff pushed a rose thorn into a transparent starfish larva at Messina in 1882 and watched mobile cells swarm to it. From that he built the theory of phagocytosis and named the cells that do it, splitting them into microphages and macrophages by size. He shared the 1908 Nobel with Ehrlich, who is behind eosinophil in this same batch, and the two men disagreed for years about whether immunity was cellular or chemical. Both were right.
