You are Louis Joseph Dufilho Jr.
, a certified apothecary and the first licensed pharmacist in the United States, in late 19th-century New Orleans. Your mission: uncover the mystery of the
Dive into the heart of New Orleans' French Quarter and unmask the dark secrets surrounding the yellow fever epidemics that ravaged the city.
« Virtue grows under the weight of adversity »— Official motto of the city of New Orleans
Your investigation begins in front of the Old Ursuline Convent Museum, a National Historic Landmark built between 1750 and 1752. This was the first brick building in the upper Mississippi region and was occupied by the Ursuline Sisters from 1727 to 1834. It was here, in the shadow of this convent, that the first victims of yellow fever were recorded during the 1796 epidemic, which claimed the lives of 600 residents of New Orleans. As an apothecary, you examine the archives and testimonies of the time, searching for clues about the early sanitary measures.
A short walk, 0.6 km away, brings you to the Gallier House at 1118-1132 Royal Street. Built in 1857 by architect James Gallier Jr. in a Greek Revival style, this house was inhabited by his family until 1907. It is now restored as a museum with 85% of its original objects. It was in this setting that the terrible yellow fever epidemic of 1853 caused over 8,000 deaths in New Orleans. You search for traces of the remedies of the time and the desperate efforts to contain the disease, observing the objects and furniture that lived through this period.
Your journey then leads you to The Cabildo, a Spanish colonial edifice built between 1795 and 1799, located in Jackson Square, 0.4 km from the convent. This building, which served as the seat of the Spanish government and the site of the Louisiana Purchase signing in 1803, also functioned as the Louisiana Supreme Court until 1853. The 1796 epidemic raged during its construction, leaving an indelible mark on the city. As Dufilho, you examine the official documents drafted there, seeking sanitary decrees or medical reports that might have escaped history.
The New Orleans Pharmacy Museum, at 514 Chartres Street, 0.3 km away, is a crucial stop. Built in 1823 by Louis J. Dufilho Jr., it was the first licensed pharmacy in the United States. This National Historic Landmark contains 19th-century medical artifacts, including treatments used against yellow fever. Here you find the instruments of your own profession, preparations, and remedies that reflect the knowledge of the era. The epidemics from 1817 to 1905 were a constant challenge for apothecaries like you, whose role was central in the fight against the disease.
Your quest concludes by walking along Royal Street, one of the main thoroughfares of the French Quarter, paved since the 1830s. This street, which runs through the entire route, was a historic commercial center where local trade was severely impacted by yellow fever in the 19th century. You conclude your investigation by observing how the city's motto, "Crescit sub pondere virtus" (Virtue grows under the weight of adversity), takes on its full meaning in the face of the resilience of New Orleans' inhabitants. You have thus explored the city's iconic sites, from St. Louis Cemetery No. 1 where Marie Laveau is buried, to the neighborhoods where quarantines were imposed, offering a unique perspective on Louisiana's heritage and the medical challenges of its history.
