Charles Richet passed away on December 4, 1935, in Paris, France. His death marked the end of a prolific career that spanned physiology, psychology, and psychical research. Richet left behind a legacy through his pioneering research on anaphylaxis, his involvement in psychical research, and his advocacy for scientific inquiry into diverse phenomena. Richet's contributions to medicine and science continue to be recognized.

In 1922, Charles Richet published the book 'Our Sixth Sense', discussing his research and theories about extrasensory perception (ESP) and psychical phenomena. This work reflected his long-standing interest in the intersection of science and the paranormal. Richet's book provided both popular and scientific audiences with insights into his explorations of human sensitivity beyond the traditional five senses.

In 1919, Charles Richet was elected as an honorary member of the Academy of Medicine of Peru. This esteemed honor acknowledged Richet's contributions to medical science, especially his groundbreaking research on anaphylaxis and related fields. His election as an honorary member of this institution reflects the international recognition he garnered for his groundbreaking work.

During World War I, Charles Richet served as a doctor in the French army. His role involved applying his extensive medical knowledge to the treatment of wounded soldiers. Richet's work during the war demonstrated his commitment to using his scientific expertise for the benefit of society, as he balanced his duties as a researcher and a military doctor during one of the most challenging periods of his time.

Charles Richet was awarded the Nobel Prize in Physiology or Medicine in 1913 for his discovery of anaphylaxis. Anaphylaxis refers to the hypersensitivity reaction that can be triggered by exposure to certain substances. Richet's groundbreaking work laid the foundation for modern understanding of allergies and the immune system's response to foreign substances. His research demonstrated the underlying mechanisms of allergic reactions.

In 1905, Charles Richet published his pivotal work on anaphylaxis, a phenomenon he first observed with Paul Portier. They discovered that dogs injected with sea anemone toxin exhibited severe reactions upon subsequent injections of the same toxin. Richet coined the term 'anaphylaxis' to describe these life-threatening allergic reactions, which fundamentally altered the scientific community's understanding of immune responses.

In 1898, Charles Richet became a founding member of the Society for Psychical Research in France. The organization aimed to investigate psychic phenomena scientifically, demonstrating Richet's broader scientific curiosity beyond his contributions to physiology. His involvement in psychical research was part of his exploration into the areas where science and the supernatural might intersect.

In 1887, Charles Richet was appointed as a professor of physiology at the Collège de France. This position marked a significant milestone in his academic career, allowing Richet to influence many students and upcoming scientists with his knowledge and research. His tenure at the Collège de France helped establish his reputation as a leader in the field of physiological research.

In 1877, Charles Richet published 'Recherches expèrirmentales et cliniques', marking one of his early major works. This publication showcased his experimental and clinical research, laying the groundwork for a distinguished career in physiological and medical research. The work highlighted Richet's innovative approach and investigative skills in the domain of physiology.

Charles Robert Richet was born on August 25, 1850, in Paris, France. He was born into a family with a scientific background, as his father was a prominent surgeon, Alfred Richet. Charles Richet would go on to become a renowned physiologist, winning the Nobel Prize in Physiology or Medicine in 1913 for his work on anaphylaxis, a kind of hypersensitivity reaction.
