François Désiré Roulin

François Désiré Roulin (August 1796 – 5 June 1874) was a French naturalist, physician and illustrator born in Rennes.

Roulin visited Colombia from 1822 to 1828, becoming an expert on the natural history of the country.

In Colombia, he also inspected the gold mines at La Vega de Supía y Marmato, and traveled the Magdalena River.

[2] Illustrations from his travels were used by Georges Cuvier in Le Règne Animal, and by Gaspard Theodore Mollien in Voyage dans la République de Colombie.

[1] Several of his watercolors were employed (with minor modifications) for the engravings that adorned Voyage pittoresque dans les deux Amériques (Paris, 1836), a book by Alcide Dessalines d'Orbigny.
