Charles Robert Richet (August 26, 1850 _ December 4, 1935) was a French physiologist who won the 1913 Nobel Prize for Physiology or Medicine for his work on anaphylaxis, his term for the sometimes fatal reaction by a sensitized individual to a second injection of an antigen. His research helped to elucidate problems of hay fever, asthma, and other allergic reactions to foreign substances and explained some cases of intoxication and sudden death not previously understood.

CharlesRobertRichetCharlesRobertRichet was the 1913 recipient of the Nobel Prize for physiology or medicine, "in recognition of his work on anaphylaxis", his term for the some times deadly reaction in a sensitised individual against a second injection of an antigen.
Richet was the son of the surgeon Louis Dominique Alfred Richet (1816-1891).
Richet was professor at the University of Paris, Sorbonne, from 1887 to 1927.
CharlesRichet was born on August 25, 1850, in Paris, the son of a professor of clinical surgery.
Richet was struck by the idea that microbes might cause disease by producing a toxin, and that immune animals might carry a substance in their blood that counteracts the toxin.
Richet called this reaction anaphylaxis, and in subsequent investigations, he and others found that it could occur as the result of exposure to a number of substances.
