title: Alexis Carrel
text: Alexis Carrel (; 28 June 1873 – 5 November 1944) was a French surgeon and biologist who was awarded the Nobel Prize in Physiology or Medicine in 1912 for pioneering vascular suturing techniques. He invented the first perfusion pump with Charles Lindbergh opening the way to organ transplantation. Carrel was also a pioneer in transplantology and thoracic surgery. He is known for his leading role in implementing eugenic policies in Vichy France.
  
  Biography 
  Born in Sainte-Foy-lès-Lyon, Rhône, Carrel was raised in a devout Catholic family and was educated by Jesuits, though he had become an agnostic by the time he became a university student. He was a member of learned societies in the U.S., Spain, Russia, Sweden, the Netherlands, Belgium, France, Vatican City, Germany, Italy, and Greece, and was elected twice, in 1924 and 1927, as an honorary member of the Academy of Sciences of the USSR. He also received honorary doctorates from Queen's University of Belfast, Princeton University, California, New York, Brown University, and Columbia University.
  
  In 1902, he was claimed to have witnessed the miraculous cure of Marie Bailly at Lourdes, which became famous in part because she named Carrel as a witness of her cure. After the notoriety surrounding the event, Carrel could not obtain a hospital appointment because of the pervasive anticlericalism in the French university system at the time. In 1903, he emigrated to Montreal, Canada, but soon relocated to Chicago, Illinois, to work for Hull Laboratory. While there he collaborated with American physician Charles Claude Guthrie in work on vascular suture and the transplantation of blood vessels and organs as well as the head, and Carrel was awarded the 1912 Nobel Prize in Physiology or Medicine for these efforts.
  
  In 1906, he joined the newly formed Rockefeller Institute of Medical Research in New York where he spent the rest of his career. There he did significant work on tissue cultures with pathologist Montrose Thomas Burrows. In the 1930s, Carrel and Charles Lindbergh became close friends not only because of the years they worked together but also because they shared personal, political, and social views. Lindbergh initially sought out Carrel to see if his sister-in-law's heart, damaged by rheumatic fever, could be repaired. When Lindbergh saw the crudeness of Carrel's machinery, he offered to build new equipment for the scientist. Eventually they built the first perfusion pump, an invention instrumental to the development of organ transplantation and open heart surgery. Lindbergh considered Carrel his closest friend, and said he would preserve and promote Carrel's ideals after his death.
  
  Due to his close proximity with Jacques Doriot's fascist Parti Populaire Français (PPF) during the 1930s and his role in implementing eugenics policies during Vichy France, he was accused after the Liberation of collaboration, but died before the trial.
  
  In his later life he returned to his Catholic roots. In 1939, he met with Trappist monk Alexis Presse on a recommendation. Although Carrel was skeptical about meeting with a priest, Presse ended up having a profound influence on the rest of Carrel's life. In 1942, he said "I believe in the existence of God, in the immortality of the soul, in Revelation and in all the Catholic Church teaches." He summoned Presse to administer the Catholic Sacraments on his death bed in November 1944.
  
  For much of his life, Carrel and his wife spent their summers on the  which they owned. After he and Lindbergh became close friends, Carrel persuaded him to also buy a neighboring island, the Ile Illiec, where the Lindberghs often resided in the late 1930s.
  
  Contributions to science
  
  Vascular suture 
  Carrel was a young surgeon who was deeply affected by the 1894 assassination of the French president, Sadi Carnot, who died from a severed portal vein that surgeons believed was irreparable. This tragedy inspired Carrel to develop new techniques for suturing blood vessels, such as the "triangulation" technique using three stay-sutures to minimize damage to the vascular wall during suturing. Carrel learned this technique from an embroideress, and later incorporated it into his work. According to Julius Comroe, Carrel performed every feat and developed every technique in vascular surgery using experimental animals between 1901 and 1910, leading to his great success in reconnecting arteries and veins and performing surgical grafts. These achievements earned him the Nobel Prize in 1912.
  
  Wound antisepsis 
  During World War I (1914–1918), Carrel and the English chemist Henry Drysdale Dakin developed the Carrel–Dakin method of treating wounds with an antiseptic solution based on chlorine, known as Dakin's solution. This method, which involved wound debridement and irrigation with a high volume of antiseptic fluid, was a significant medical advancement in the absence of antibiotics. For his contributions, Carrel was awarded the Légion d'honneur. The Carrel–Dakin method became widely used in hospitals. The mechanical irrigation technique developed by Carrel is still used today.<ref name=dakin3>H. D. Dakin (1915): Comptes rendues de la Academie des Sciences, CLXI, p. 150.

   Organ transplants 
  Carrel co-authored a book with pilot Charles Lindbergh, The Culture of Organs. Together, they developed the perfusion pump in the mid-1930s, which made it possible for organs to remain viable outside of the body during surgical procedures. This innovation is considered to be a significant advancement in the fields of open-heart surgery and organ transplantation, and it paved the way for the development of the artificial heart, which became a reality many years later. Although some critics accused Carrel of exaggerating Lindbergh's contributions to gain publicity, other sources indicate that Lindbergh played a significant role in the device's development. In recognition of their groundbreaking work, both Carrel and Lindbergh appeared on the cover of Time magazine on June 13, 1938.
  
   Cellular senescence 
  Carrel was interested in the phenomenon of senescence or aging. He believed that all cells continued to grow indefinitely, which became a widely accepted view in the early 20th century. In 1912, Carrel began an experiment at the Rockefeller Institute for Medical Research, where he cultured tissue from an embryonic chicken heart in a stoppered Pyrex flask of his own design. He supplied the culture with nutrients regularly and maintained it for over 20 years, longer than a chicken's normal lifespan. This experiment received significant popular and scientific attention, but it was never successfully replicated.
  
  In the 1960s, Leonard Hayflick and Paul Moorhead proposed the concept of the Hayflick limit, which states that differentiated cells undergo only a limited number of divisions before dying. Hayflick suggested that Carrel's daily feeding of nutrients continually introduced new living cells to the culture, resulting in anomalous results. J. A. Witkowski argued that the deliberate introduction of new cells into the culture, possibly without Carrel's knowledge, could also explain the results.
  
  Despite the doubts surrounding Carrel's experiment, it remains an important part of scientific history, and his work on tissue culture had a significant impact on the development of modern medicine.
  
   Honors 
  In 1972, the Swedish Post Office honored Carrel with a stamp that was part of its Nobel stamp series. Seven years later, in 1979, the lunar crater Carrel was named after him as a tribute to his breakthroughs. In February 2002, to celebrate the 100th anniversary of Charles Lindbergh's birth, the Lindbergh-Carrel Prize was established by the Medical University of South Carolina at Charleston. Michael DeBakey and nine other scientists were the first recipients of the prise, a bronze statuette, named "Elisabeth" after Elisabeth Morrow, the sister of Lindbergh's wife Anne Morrow who died from heart disease. Lindbergh's frustration with the limitations of medical technology, specifically the lack of an artificial heart pump for heart surgery, led him to reach out to Carrel.
  
   Alexis Carrel and Lourdes 
  In 1902, Carrel underwent a transformative experience that led him from being a skeptic of the reported visions and miracles at Lourdes to a believer in spiritual cures. This conversion came about after he witnessed the inexplicable healing of Marie Bailly. The Catholic journal Le Nouvelliste reported that she identified Carrel as the principal witness of her cure. Despite facing opposition from his peers in the medical community, Carrel refused to dismiss a supernatural explanation for the event and went on to publish his account of the experience in the book, The Voyage to Lourdes, which was released four years after his death. However, his beliefs proved to be a hindrance to his career and reputation in academic medicine in France. As a result, Carrel moved to Canada with plans of farming and raising cattle. But, shortly after, he accepted a position at the University of Chicago, where he remained for two years before taking up a post at the Rockefeller Institute of Medical Research.
  
   Man, the Unknown (1935, 1939) 
  
  In 1935, Carrel's book, L'Homme, cet inconnu (Man, the Unknown), became a best-seller. The book attempted to comprehensively outline what is known, and unknown, of the human body and human life "in light of discoveries in biology, physics, and medicine", to shed light on the problems of the modern world, and to provide possible routes to a better life for human beings. In the book, Carrel advocated for an elite group of intellectuals to guide mankind and to incorporate eugenics into the social framework. He argued for an aristocracy that would come from individuals of potential and advocated for euthanasia for criminals and the criminally insane. Notably, Carrel's endorsement of euthanasia for criminals and the criminally insane was published in the mid-1930s, prior to the implementation of death camps and gas chambers in Nazi Germany. In the 1936 German introduction of his book, Carrel added praise for the Nazi regime at the publisher's request, which did not appear in other language editions. After the second world war the book and his role with the Vichy regime would stain his reputation such that his name was removed from streets in more than 20 French cities and the Alexis Carrel Medical Faculty in Lyon was renamed in 1996.
  
   French Foundation for the Study of Human Problems 
  
  In 1937, Carrel joined the Centre d'Etudes des Problèmes Humains, which was led by Jean Coutrot. Coutrot's goal was to develop what he called an "economic humanism" through "collective thinking." However, in 1941, Carrel went on to advocate for the creation of the French Foundation for the Study of Human Problems (Fondation Française pour l'Etude des Problèmes Humains). This foundation was created by decree of the Vichy regime in 1941, and Carrel served as a "regent." Carrel's connections to the cabinet of Vichy France president Philippe Pétain, specifically French industrial physicians André Gros and Jacques Ménétrier, helped pave the way for the creation of the foundation.
  
  The foundation played a significant role in the establishment of the field of occupational medicine, which was institutionalized by the Provisional Government of the French Republic (GPRF) through the 11 October 1946 law. The foundation's efforts were not limited to occupational medicine and extended to other areas such as demographics, economics, nutrition, habitation, and opinion polls. Notable figures associated with the foundation's work include Robert Gessain, Paul Vincent, Jean Bourgeois-Pichat, François Perroux, Jean Sutter, and Jean Stoetzel. The foundation achieved several notable accomplishments throughout its history. It played a crucial role in the promotion of the 16 December 1942 Act, which mandated the use of a prenuptial certificate before marriage. This certificate aimed to ensure the good health of spouses, particularly regarding sexually transmitted diseases (STDs) and "life hygiene." Additionally, the institute created the livret scolaire, a document that recorded the grades of French secondary school students, allowing for the classification and selection of students based on academic performance.
  
  Gwen Terrenoire's book, "Eugenics in France (1913–1941): a review of research findings," describes the Foundation for the Study of Human Problems as a pluridisciplinary center that employed approximately 300 researchers, primarily statisticians, psychologists, and physicians, from the summer of 1942 until the end of autumn 1944. Following the liberation of Paris, Alexis Carrel, the founder, was suspended by the Minister of Health, and he died in November 1944. However, the Foundation underwent a purge and emerged shortly afterward as the Institut national d'études démographiques (INED), which is still active today. Although Carrel had passed away, most of his team transferred to INED, which was headed by demographer Alfred Sauvy, who coined the term "Third World." Other team members joined the Institut national d'hygiène (National Hygiene Institute), later known as INSERM.
