Alexis Carrel (French: [alɛksi kaʁɛl]; 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 A. Lindbergh opening the way to organ transplantation. His positive description of a miraculous healing he witnessed during a pilgrimage earned him scorn by some of his colleagues. This prompted him to relocate to the United States, where he lived most of his life. He had a leading role in implementing eugenic policies in Vichy France.
A Nobel Prize laureate in 1912, Alexis Carrel was also elected twice, in 1924 and 1927, as an honorary member of the Academy of Sciences of the USSR.

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 pioneer in transplantology and thoracic surgery. Alexis Carrel was also a member of learned societies in the U.S., Spain, Russia, Sweden, the Netherlands, Belgium, France, Vatican City, Germany, Italy, and Greece. Additionally, he 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, made 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 Île Saint-Gildas [fr], 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 in 1894, when the French president Sadi Carnot was assassinated with a knife. Carnot bled to death due to severing of his portal vein, and surgeons who treated the president felt that the vein could not be successfully reconnected. This left a deep impression on Carrel, and he set about developing new techniques for suturing blood vessels. The technique of "triangulation", using three stay-sutures as traction points in order to minimize damage to the vascular wall during suturing, was inspired by sewing lessons he took from an embroideress and is still used today. Julius Comroe wrote: "Between 1901 and 1910, Alexis Carrel, using experimental animals, performed every feat and developed every technique known to vascular surgery today." He had great success in reconnecting arteries and veins, and performing surgical grafts, and this led to his 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 based on chlorine (Dakin's solution) which, preceding the development of antibiotics, was a major medical advance in the care of traumatic wounds. For this, Carrel was awarded the Légion d'honneur. Carrel also advocated the use of wound debridement (cutting away necrotic or otherwise damaged tissue) and irrigation of wounds. His method of wound irrigation involved flushing the tissues with a high volume of antiseptic fluid so that dirt and other contaminants would be washed away (this is known today as "mechanical irrigation.") The World War I era Rockefeller War Demonstration Hospital (United States Army Auxiliary Hospital No.
Organ transplants
Carrel co-authored a book with pilot Charles A. Lindbergh, The Culture of Organs, and worked with Lindbergh in the mid-1930s to create the "perfusion pump," which allowed living organs to exist outside the body during surgery. The advance is said to have been a crucial step in the development of open-heart surgery and organ transplants, and to have laid the groundwork for the artificial heart, which became a reality decades later. Some critics of Lindbergh claimed that Carrel overstated Lindbergh's role to gain media attention, but other sources say Lindbergh played an important role in developing the device. Both Lindbergh and Carrel appeared on the cover of Time magazine on 13 June 1938.
Cellular senescence
Carrel was also interested in the phenomenon of senescence, or aging. He claimed that all cells continued to grow indefinitely, and this became a dominant view in the early 20th century. Carrel started an experiment on 17 January 1912, where he placed tissue cultured from an embryonic chicken heart in a stoppered Pyrex flask of his own design. He maintained the living culture for over 20 years with regular supplies of nutrient. This was longer than a chicken's normal lifespan. The experiment, which was conducted at the Rockefeller Institute for Medical Research, attracted considerable popular and scientific attention.
Carrel's experiment was never successfully replicated, and in the 1960s Leonard Hayflick and Paul Moorhead proposed that differentiated cells can undergo only a limited number of divisions before dying. This is known as the Hayflick limit, and is now a pillar of biology.
It is not certain how Carrel obtained his anomalous results. Leonard Hayflick suggests that the daily feeding of nutrient was continually introducing new living cells to the alleged immortal culture. J. A. Witkowski has argued that, while "immortal" strains of visibly mutated cells have been obtained by other experimenters, a more likely explanation is deliberate introduction of new cells into the culture, possibly without Carrel's knowledge.
Honors
In 1972, the Swedish Post Office honored Carrel with a stamp that was part of its Nobel stamp series. In 1979, the lunar crater Carrel was named after him as a tribute to his scientific breakthroughs.
In February 2002, as part of celebrations of the 100th anniversary of Charles Lindbergh's birth, the Medical University of South Carolina at Charleston established the Lindbergh-Carrel Prize, given to major contributors to "development of perfusion and bioreactor technologies for organ preservation and growth". Michael DeBakey and nine other scientists received the prize, a bronze statuette created for the event by the Italian artist C. Zoli and named "Elisabeth" after Elisabeth Morrow, sister of Lindbergh's wife Anne Morrow, who died from heart disease. It was in fact Lindbergh's disappointment that contemporary medical technology could not provide an artificial heart pump which would allow for heart surgery on her that led to Lindbergh's first contact with Carrel.
Alexis Carrel and Lourdes
In 1902, Alexis B went from being a skeptic of the visions and miracles reported at Lourdes to being a believer in spiritual cures after experiencing a healing of Marie Bailly that he could not explain. The Catholic journal Le nouvelliste reported that she named him as the prime witness of her cure. Alexis Carrel refused to discount a supernatural explanation and steadfastly reiterated his beliefs, even writing the book The Voyage to Lourdes describing his experience, although it was not published until four years after his death. This was a detriment to his career and reputation among his fellow doctors, and feeling he had no future in academic medicine in France, he emigrated to Canada with the intention of farming and raising cattle. After a brief period, he accepted an appointment at the University of Chicago and, two years later, at the Rockefeller Institute of Medical Research.
Man, the Unknown (1935, 1939)
_(14789532853).jpg)
In 1935, Carrel published a book titled L'Homme, cet inconnu (Man, the Unknown), which became a best-seller. In the book, he attempted to outline a comprehensive account of what is known and more importantly unknown of the human body and human life "in light of discoveries in biology, physics, and medicine", to elucidate problems of the modern world, and to provide possible routes to a better life for human beings.
Carrel advocated, in part, that mankind could better itself by following the guidance of an elite group of intellectuals, and by incorporating eugenics into the social framework. He argued for an aristocracy springing from individuals of potential, writing:
_(14595636487).jpg)
Otherwise he endorsed voluntary positive eugenics.
He continued:
The progress of the strong depends on the conditions of their development and the possibility left to parents of transmitting to their offspring the qualities which they have acquired in the course of their existence. Modern society must, therefore, allow to all a certain stability of life, a home, a garden, some friends. Children must be reared in contact with things which are the expression of the mind of their parents. It is imperative to stop the transformation of the farmer, the artisan, the artist, the professor, and the man of science into manual or intellectual proletarians, possessing nothing but their hands or their brains. The development of this proletariat will be the everlasting shame of industrial civilization. It has contributed to the disappearance of the family as a social unit, and to the weakening of intelligence and moral sense. It is destroying the remains of culture. All forms of the proletariat must be suppressed. Each individual should have the security and the stability required for the foundation of a family. Marriage must cease being only a temporary union. The union of man and woman, like that of the higher anthropoids, ought to last at least until the young have no further need of protection. The laws relating to education, and especially to that of girls, to marriage, and divorce should, above all, take into account the interest of children. Women should receive a higher education, not in order to become doctors, lawyers, or professors, but to rear their offspring to be valuable human beings.
The free practice of eugenics could lead not only to the development of stronger individuals, but also of strains endowed with more endurance, intelligence, and courage. These strains should constitute an aristocracy, from which great men would probably appear. Modern society must promote, by all possible means, the formation of better human stock. No financial or moral rewards should be too great for those who, through the wisdom of their marriage, would engender geniuses. The complexity of our civilization is immense. No one can master all its mechanisms. However, these mechanisms have to be mastered. There is need today of men of larger mental and moral size, capable of accomplishing such a task. The establishment of a hereditary biological aristocracy through voluntary eugenics would be an important step toward the solution of our present problems.
Carrel's endorsement of euthanasia of the criminal and insane was published in the mid-1930s, prior to the implementation of death camps and gas chambers in Nazi Germany.
French Foundation for the Study of Human Problems
_(17537880474).jpg)
In 1937, Carrel joined Jean Coutrot's Centre d'Etudes des Problèmes Humains - Coutrot's aim was to develop what he called an "economic humanism" through "collective thinking." In 1941, through connections to the cabinet of Vichy France president Philippe Pétain (specifically, French industrial physicians André Gros and Jacques Ménétrier) he 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 which was created by decree of the Vichy regime in 1941, and where he served as "regent".
The foundation was at the origin of the 11 October 1946 law, enacted by the Provisional Government of the French Republic (GPRF), which institutionalized the field of occupational medicine. It worked on demographics (Robert Gessain, Paul Vincent, Jean Bourgeois-Pichat), on economics, (François Perroux), on nutrition (Jean Sutter), on habitation (Jean Merlet) and on the first opinion polls (Jean Stoetzel). "The foundation was chartered as a public institution under the joint supervision of the ministries of finance and public health. It was given financial autonomy and a budget of forty million francs—roughly one franc per inhabitant—a true luxury considering the burdens imposed by the German Occupation on the nation's resources. By way of comparison, the whole Centre National de la Recherche Scientifique (CNRS) was given a budget of fifty million francs."
The Foundation made many positive accomplishments during its time. It promoted the 16 December 1942 Act which established the prenuptial certificate, which was required before marriage, and was aimed at insuring the good health of the spouses. The institute also established the livret scolaire, which could be used to record students' grades in the French secondary schools, and thus classify and select them according to scholastic performance.
According to Gwen Terrenoire, writing in Eugenics in France (1913–1941) : a review of research findings, "The foundation was a pluridisciplinary centre that employed around 300 researchers (mainly statisticians, psychologists, physicians) from the summer of 1942 to the end of the autumn of 1944. After the liberation of Paris, Carrel was suspended by the Minister of Health; he died in November 1944, but the Foundation itself was "purged", only to reappear in a short time as the Institut national d'études démographiques (INED) that is still active." Although Carrel himself was dead most members of his team did move to the INED, which was led by demographist Alfred Sauvy, who coined the expression "Third World". Others joined Robert Debré's "Institut national d'hygiène" (National Hygiene Institute), which later became the INSERM.
