Félix Vicq d'Azyr (born April 23, 1748 – died June 20, 1794) was an important French doctor and scientist. He is known for starting the study of comparative anatomy, which compares the body structures of different animals. He also discovered the idea of homology in biology. This means that similar body parts in different species can come from a common ancestor.

Life and Work
Félix Vicq d'Azyr was born in Valognes, a town in Normandy, France. His father was also a doctor. Félix studied medicine at the University of Paris. He became a very skilled doctor and expert in studying the bodies of both animals and humans.
Teaching and Academies
Starting in 1773, Vicq d'Azyr taught popular anatomy classes. These classes were held at the Jardin du Roi in Paris, which is now the Museum of Natural History. In 1774, he became a member of the Académie des Sciences, a famous French science academy. His friend Condorcet, who was the Perpetual Secretary, helped him join.
As Perpetual Secretary, Vicq d'Azyr was responsible for writing special speeches. These speeches honored his colleagues who had passed away. He was very good at this, which led him to become a lifetime member of the Académie française in 1788. This is one of France's most important academies.
Public Health and Medicine
When a serious illness spread in a region called Guyenne, Vicq d'Azyr was asked to help. He wrote a report and suggested ways to deal with the problem. He believed that the government should be involved in public health.
In 1775, a new group called the Société Royale de Médecine (Royal Society of Medicine) was created. Vicq d'Azyr became its Perpetual Secretary. Under his leadership, the Society collected a lot of information over 16 years. This included facts about diseases, doctors, and even food supplies.
He also worked as a professor of veterinary medicine at the School of Alfort. This school teaches about animal health. He was also in charge of dealing with epidemics, which are widespread outbreaks of disease.
Royal Physician
Vicq d'Azyr was the last doctor to Queen Marie-Antoinette. He tried to protect her during a very difficult time in France.
Discoveries in Anatomy
As an anatomist, Vicq d'Azyr made important contributions to understanding the brain. He was one of the first scientists to cut the brain into thin slices from front to back. This method is called using "coronal sections." He also used alcohol to help preserve and study tissues during dissection.
Brain Structures
In 1786, he described two important parts of the brain: the locus coeruleus and the locus niger (which is now called the substantia nigra). He also identified the band of Vicq d'Azyr. This is a system of fibers in the cerebral cortex, which is the outer layer of the brain. Another part of the brain, the Mamillo-thalamic tract, is named after him.
He carefully studied the folds and grooves on the surface of the brain, called cerebral convolutions. His work on this became a classic study. Vicq d'Azyr was one of the first neuroanatomists to give names to these brain folds. He also studied the deep gray areas of the cerebrum and the basal ganglia, which are important for movement. He helped create the Second Encyclopedia, a large collection of knowledge.
Later Life
During the French Revolution, Vicq d'Azyr was chosen to be part of a special committee. This committee was tasked with deciding the future of anatomy education in France.
Félix Vicq d'Azyr died from tuberculosis on June 20, 1794. This was during a period known as The Terror in France. He had attended a public event that day. His life story describes him as being very worried and having nightmares in his final years.
Some of his important papers and writings are kept at the National Library of Medicine in Bethesda, Maryland.
