The discovery and characterisation of the genes constituting the major histocompatibility complex earned Jean Dausset the 1980 Nobel Prize in Physiology or Medicine. A French physician and immunologist, Dausset transformed clinical transplantation through his study of leucocytes and antigens, ultimately bridging the gap between genetic research and practical medicine to improve patient outcomes during organ and bone marrow procedures.
Early Career and War Service
Born in Toulouse in 1916, Dausset relocated to Paris for his formal education, eventually entering the Paris Medical Faculty. Following the outbreak of World War II, he served in the French army before joining the Free French Forces in North Africa. While stationed in Tunisia, he performed numerous blood transfusions on wounded soldiers, gaining his initial experience in hematology. After returning to Paris in 1944, he worked at the Saint-Antoine Hospital, where he encountered the practical challenges of transfusion medicine.

In the postwar period, Dausset became involved in efforts to reform the dilapidated French hospital system. Collaborating with Robert Debré, he participated in a movement to integrate research facilities directly into clinical environments. These efforts culminated in the reform of December 1958, which established a formal system of university research hospitals and introduced mandatory teaching duties for medical professionals, modernizing the structure of French medical education.
Immunogenetics and Transplantation
Dausset spent four years at a children's hospital in Boston starting in 1948 before returning to France to collaborate with Marcel Bessis. His focus on immunohematology led to the 1958 description of the first antigen-presenting leucocyte, identified through an antibody he named MAC. Building on this, his work during the 1960s with colleagues such as Felix Rapaport identified the HLA system, proving that the success of skin transplants relied on histocompatibility. He later founded France Transplant and France Greffe de Moelle to manage the allocation of organs and bone marrow.
Legacy and Institutional Leadership
Throughout his career, Dausset held key positions at the Collège de France and the French National Institute of Health and Medical Research. In 1984, he established the Human Polymorphism Study Center, now known as the Foundation Jean Dausset-CEPH. A member of numerous international scientific bodies, including the French Academy of Sciences and the National Academy of Sciences, he received multiple honors, including the 1977 Wolf Prize in Medicine and the CNRS silver medal. He died in 2009 in Palma, Mallorca.
