Laveran

The plasmodium malari was discovered by Laveran in 1880, in the blood of malarial patients.

Laveran traced out the life cycle of the malarial parasite as it occurs in man.

They passed on indifferently, commending Laveran's "effort of genius," repeating with him: They are degenerate forms.

It may be said that this "feat of genius," this visionary generalization, prevented Laveran from seeing the truth.

Laveran proved the association of haematozoa with malaria in 1880.
