Charles Robert Richet was a prominent French physiologist born August 26 of 1850 and died December 4 of 1935. Best known for his experimental studies of allergic reactions, Richet received the 1913 Nobel Prize in Physiology or Medicine for work that established the concept of anaphylaxis. He is remembered for both his lasting scientific contributions and for interests that later attracted criticism.

Overview of career and research

Richet trained in medicine and physiology in France and spent much of his career in academic research and teaching. His experimental approach combined laboratory physiology with careful observation of clinical phenomena, and he investigated a range of topics including reflexes, circulation and responses to toxins. The studies that earned him the Nobel Prize clarified how prior exposure to a substance can produce a heightened, sometimes dangerous, response on re-exposure.

Scientific contributions and anaphylaxis

In the early 20th century Richet described and coined the practical concept that became known as anaphylaxis: a paradoxical hypersensitivity in which a second contact with a previously encountered agent can provoke severe, sometimes life‑threatening, reactions. This work helped found modern understanding of allergy, hypersensitivity and immune-related shock, and influenced diagnostic and therapeutic approaches in immunology and clinical medicine.

Other interests and controversies

Outside mainstream physiology, Richet took an active role in then‑emerging psychical research, studying reports of telepathy, mediumship and related claims. He published on these subjects and attended investigations that blended scientific methods with phenomena now described as parapsychology. Later in life he also expressed views on heredity and population that aligned with contemporary eugenic thinking; these positions have been widely criticized by later historians and ethicists.

Legacy

  • Major honor: Nobel Prize in Physiology or Medicine, 1913, for research into anaphylaxis.
  • Influence: helped establish concepts central to allergy and immunology.
  • Controversy: active in psychical research and associated with eugenic ideas, complicating his historical reputation.
