Louis Duret

Louis Duret was a French physician to Charles IX of France and his brother Henry III of France as their chief physician.

Duret was born in Bâgé-la-Ville in the French province of Bresse (which then belonged to the Duke of Savoy) in the year 1527. He came from a minor French nobility family. Leaving his father's home as a teenager. he made little money and subsisted at the poverty level. Around age nineteen, Duret decided to go to Paris to seek a good career. At first he was trained in academic disciplines by a private tutor, French magistrate Achilles Harlay, who took him under his wing because he demonstrated talent in many academic fields, especially the languages of Latin, Greek, and Arabic, which were integral to medicine. Duret had a photographic memory and knew all the works of Hippocrates by heart.

Duret studied medicine under the training of Jacques Houllier and Jacques Dubois. He studied the medicine field with much vigor with his skills of the languages he knew, which proved helpful in his new career of medicine. He soon occupied a position at the Collège de France. His excellent reputation spread rapidly. He became a professor and ultimately taught at this college, a position he held for eighteen years (1568–1586).

Philosophically, he was firmly attached to Hippocrates and the Hippocratic oath, with roots in ancient medical practice. So esteemed was he that Henry III granted him a pension of "four hundred crowns of gold."

Duret's father was Jean Duret. He had a son, Charles Duret, that was superintendent of finance. He also had another son, Jean Duret (1563–1629), who was physician to Queen Marie de Medici. When Duret's daughter Catherine Arnoult de Lisle married in 1586, King Henry III attended the wedding and gave her a lucrative financial endowment, honoring Duret's services as a medical doctor.

Sometimes in Old French the source says the spelling of his surname is "Duket".

Duret died in Paris on 22 January 1586.
