The career of Louis-Isidore Duperrey began in 1802 when he entered the French navy, eventually transitioning from a marine hydrologist to a commanding officer. His contributions to geography centered on meticulous hydrographic surveys during long-range maritime expeditions, fundamentally altering the existing maps of the Pacific region during the early nineteenth century.
Naval Training and Early Service
Joining the French navy at the start of the nineteenth century provided the foundation for his later work as an explorer. Between 1817 and 1820, he served as a marine hydrologist under Louis Claude de Saulces de Freycinet. This service aboard the Uranie allowed him to refine his skills in hydrography and cartography, which were critical for the subsequent scientific missions he would eventually lead.

Commanding the vessel La Coquille, Duperrey undertook a circumnavigation of the earth between 1822 and 1825. His crew included second-in-command Jules Dumont d'Urville and naval doctor René-Primevère Lesson. Throughout the journey, the expedition collected extensive biological and botanical specimens from diverse locations, including the Falkland Islands, Chile, Peru, Australia, New Guinea, and New Zealand. The crew conducted a two-week survey of the Bay of Islands in New Zealand in 1824 and spent ten days observing l'île d'Oualan, known today as Kosrae in the Federated States of Micronesia.
Cartographic Contributions
During his return voyage to France, Duperrey traversed the Ellice Islands, currently recognized as Tuvalu. His most notable cartographic achievement was the successful integration of the entire Gilbert Islands archipelago into a single map. By applying the name suggested by Admiral Krusenstern, he consolidated geographic knowledge of these islands, which are now part of modern-day Kiribati.
Academic Recognition and Later Years
His expertise earned him a seat at the French Academy of Sciences in 1842. He served as the academy's vice president in 1849 and ascended to the presidency in 1850. Beyond his domestic duties, he was recognized internationally as a Fellow of the American Academy of Arts and Sciences, receiving this honor in 1861. Following his death in Paris in 1865, his legacy remained embedded in scientific nomenclature through the Australian eastern three-lined skink, Bassiana duperreyi, and two plant genera: Duperreya, established in 1829, and Duperrea, established in 1924.
