[1] Faget was then admitted into the University of Paris' college of internal medicine and graduated magna cum laude in 1845.

[1] He returned to New Orleans and married Glady Ligeret de Chazey and became the father of thirteen children.

They had similar backgrounds to Faget either being the children of refugees from Santo Domingo or the upheavals of the French Revolution and ensuing rule by Napoleon I. Faget's education in Paris entered him into an elite circle of physicians known as the Société Médicale de la Nouvelle-Orléans.

Early scientists believed that it was caused by environmental problems like rotting food, weather conditions, and poor sanitation.

[1] Faget also became convinced that yellow fever could be traced to a specific microorganism that came to New Orleans via foreign shipping.

He thought that the small organisms were spawned by a combination of rotting matter in ships' holds and the heat and humidity of the city.

Faget served his community by holding a position on the New Orleans Sanitary Commission and as a member of the Louisiana Board of Health.

He went back to Paris for two years after the American Civil War where he was named a chevalier, a Knight of the Legion of Honour by Napoleon III after helping relieve an epidemic in France.
