Biography
François Désiré Roulin (August 1796 – 5 June 1874) was a French naturalist, physician, and illustrator from Rennes. After studying medicine at the University of Paris from 1815 to 1820, he started a career that mixed scientific research with fieldwork, becoming known as one of the keen observers of South American nature in the early 1800s. He was made an Officer of the Legion of Honour for his contributions to science and public service.
Roulin spent six key years in Colombia, from 1822 to 1828, where he carefully documented the country's plants, animals, and geography. In 1824, he joined a Colombian expedition to survey the Meta River, a major tributary of the Orinoco River. Besides this trip, he inspected gold mines at La Vega de Supía y Marmato and traveled widely along the Magdalena River. His journeys extended beyond Colombia to Venezuela, Peru, and Ecuador, giving him wide firsthand knowledge of northwestern South America's natural environment.
The illustrations and notes Roulin collected during his travels in South America were included in some major scientific and geographical publications of the time. The well-known zoologist Georges Cuvier used his illustrations in Le Règne Animal, a key text on comparative anatomy. Gaspard Théodore Mollien also used Roulin's work for his Voyage dans la République de Colombie. Some of Roulin's watercolors were adapted, with slight changes, for engravings in Alcide Dessalines d'Orbigny's Voyage pittoresque dans les deux Amériques, published in Paris in 1836.
After returning to France, Roulin moved from fieldwork to a role in Parisian intellectual circles. Starting in 1832, he worked as a librarian at the Bibliothèque de l'Arsenal and later at the Institut de France from 1865. During these years, he wrote many articles for top French journals like Le Globe, Le Temps, La Revue des Deux Mondes, and Le Magasin pittoresque, staying involved with the wider scientific and literary communities in Paris.
Roulin had family connections to several notable French intellectuals. He was the son-in-law of politician Joseph Blin (1764–1834), and through family ties, he was uncle to mathematician Joseph Bertrand (1822–1900) and archaeologist Alexandre Bertrand (1820–1902). He passed away in Paris on 5 June 1874.
Before Fame
François Désiré Roulin, born in Rennes in August 1796, came into the world when France was still finding its footing after the Revolution. He received a strong scientific education, attending the École Polytechnique before studying medicine at the University of Paris, completing his studies between 1815 and 1820. This mix of medicine and natural sciences was common among French scholars of his time.
After his medical training, Roulin became interested in the newly independent republics of South America, which were attracting a lot of European scientific interest. Colombia's independence in the early 1820s opened the area to foreign travelers and researchers, and Roulin was one of the first French naturalists to seize this opportunity. He left for Colombia in 1822, just two years after finishing his medical degree, which marked the start of the most productive period of his scientific work.
