'''Jules Sébastien César Dumont d'Urville''' ({{IPA|fr|ʒyl dymɔ̃ dyʁvil}}; 23 May 1790 – 8 May 1842) was a French [[List of explorers|explorer]] and [[French Navy|naval officer]] who explored the south and western Pacific, Australia, New Zealand and [[Antarctica]]. As a botanist and cartographer, he gave his name to several seaweeds, plants and shrubs and to places such as [[d'Urville Island]] in New Zealand.

==Early life and education==
{{Unreferenced section|date=October 2022}}
Dumont was born at [[Condé-sur-Noireau]] in [[Lower Normandy]].<ref>{{cite EB1911 |wstitle=Dumont d'Urville, Jules Sébastien César |volume=8 |page=666}}</ref> His father, Gabriel Charles François Dumont, sieur d'Urville (1728–1796), [[Bailiff]] of Condé-sur-Noireau, was, like his ancestors, responsible to the court of Condé.

His mother Jeanne Françoise Victoire Julie (1754–1832) came from [[Croisilles, Calvados]], and was a rigid and formal woman from an ancient family of the rural nobility of Lower Normandy. The child was weak and often sickly.

After the death of his father when he was six, his mother's brother, the Abbot of [[Croisilles, Calvados|Croisilles]], played the part of his father and from 1798 took charge of his education. The Abbot taught him [[Latin]], [[Ancient Greek|Greek]], [[rhetoric]] and [[philosophy]]. From 1804 Dumont studied at the ''lycée Impérial'' in [[Caen]].

In the library of Caen, he read the [[Encyclopédistes]] and the reports of travel of [[Louis Antoine de Bougainville|Bougainville]], [[James Cook|Cook]] and [[George Anson, 1st Baron Anson|Anson]], and he became  passionate about these matters.

At the age of 17 years he failed the physical tests of the entrance exam to the [[École polytechnique]] and he therefore decided to enlist in the navy.<ref group="note">This was to the relief of his mother, who disapproved the idea of her son entering a [[laity|lay]] institution characterised by "...maîtres athées, promiscuité des condisciples venus de tous les milieux, contagion des idées philosophiques et révolutionnaires..." ("atheistic teachers, the promiscuity of school-fellows from all parts of society, the contagion of philosophical and revolutionary ideas")<br>(Guillon 1986)</ref>

==Military career==
{{more citations needed|section|date=October 2022}}
In 1807, Dumont was admitted to the [[École navale]] at [[Brest, France|Brest]] where he presented himself as a timid young man, very serious and studious, little interested in amusements and much more interested in studies than in military matters. In 1808, he obtained the grade of first-class candidate.<ref>{{cite web|url=http://micsem.org/pubs/articles/historical/frames/chuukcarfr.htm|title=Chuuk: The Caricature of An Island|access-date=18 January 2015}}</ref>

At the time the neglected [[History of the French Navy|French navy]] was of a much lower quality than [[Napoleon]]'s [[Grande Armée]], and its ships were blockaded in their ports by the absolute domination of the British [[Royal Navy]].  Dumont was confined to land like his colleagues and spent the first years in the navy studying foreign languages.

In 1812, after having been promoted to [[Ensign (rank)|ensign]] and finding himself bored with port life and disapproving of the dissolute behaviour of the other young officers, he asked to be transferred to [[Toulon]] on board the ''[[French ship Suffren (1803)|Suffren]]''; but this ship was also blockaded in port.

During this period, Dumont built on his already substantial cultural knowledge. He already spoke, in addition to Latin and Greek, English, German, Italian, Russian, Chinese and Hebrew. During his later travels in the Pacific, thanks to his prodigious memory, he would acquire some knowledge of an immense number of dialects of [[Polynesia]] and [[Melanesia]]. Meanwhile, ashore at Toulon, he learnt about [[botany]] and [[entomology]] in long excursions in the hills of [[Provence]] and he studied in the nearby naval [[observatory]].

Finally in 1814, when Napoleon had been exiled to [[Elba]], Dumont undertook his first short navigation of the [[Mediterranean Sea]]. In 1815, he married [[Adèle Dumont D'Urville|Adèle Pépin]], daughter of a clockmaker from Toulon.<ref>{{Cite web|url=https://teara.govt.nz/en/biographies/1d19/dumont-durville-jules-sebastien-cesar|title=Dumont d'Urville, Jules Sébastien César|last=Taonga|first=New Zealand Ministry for Culture and Heritage Te Manatu|website=TEARA|language=en|url-status=dead|archive-url=https://web.archive.org/web/20190317023307/https://teara.govt.nz/en/biographies/1d19/dumont-durville-jules-sebastien-cesar|archive-date=17 March 2019|access-date=2020-02-13}}</ref> who was openly disliked by Dumont's mother, who thought her inappropriate for her son and refused to meet her.<ref>{{Cite book|last=Dunmore|first=John|url=https://books.google.com/books?id=HEqnFLnTNscC&q=Ad%C3%A8le+Pepin&pg=PA16|title=From Venus to Antarctic: The Life of Dumont D'Urville|date=2010-11-07|publisher=ReadHowYouWant|isbn=978-1-4587-7965-6|page=17|language=en}}</ref>

=== In the Aegean Sea ===
In 1819, Dumont d'Urville sailed on board ''Chevrette'', under the command of Captain [[Pierre Henri Gauttier Duparc|Gauttier-Duparc]], to carry out a [[hydrographic survey]] of the islands of the Greek archipelago. During a pause near the island of [[Milos]], the local French representative brought to Dumont's attention the rediscovery of a marble statue a few days before (8 April 1820) by a local [[peasant]].  The statue, now known as the ''[[Venus de Milo]]'', dates from around the year 130 BC.

Dumont recognised its value and would have acquired it immediately, but the ship's commander pointed out that there was not enough space on board for an object of its size.  Moreover, the expedition was likely to proceed through stormy seas that could damage it.  Dumont then wrote to the French ambassador to [[Constantinople]] about its discovery.<ref group="note">”... je fus le premier à en remettre une description détaillée à M. le marquis de Rivière, à Constantinople. Grâce à son empressement, à son amour pour les beaux arts et aux efforts de M. de Marcellus, la France n'a pas eu le regret de voir passer en mains étrangères ce précieux reste d'antiquité...” (“…I was the first one to supply a detailed description to the [[Charles François de Riffardeau, marquis de Rivière|M. le marquis de Rivière]], in Constantinople.  Thanks to his enthusiasm, his love of fine arts and to the efforts of M. de Marcellus, France has been able to avoid the regret to see this precious piece of antiquity pass into foreign hands…”) Note on the underground galleries of the island of Milos, by J. Dumont d’Urville, in ''Nouvelles annales des voyages, de géographie et de histoire'', volume XXVII. Paris: Gide, 1825.{{in lang|fr}}
</ref> ''Chevrette'' arrived in Constantinople on 22 April and Dumont succeeded in convincing the ambassador to acquire the statue.

Meanwhile, the peasant had sold the statue to a priest, Macario Verghis, who wished to present it as a gift to an interpreter for the [[Sultan]] in Constantinople.  The French ambassador's representative arrived just as the statue was being loaded aboard a ship bound for Constantinople and persuaded the island's primates (chief citizens) to annul the sale and honour the first offer.  This earned Dumont the title of ''Chevalier'' ([[knight]]) of the [[Légion d'honneur]], the attention of the [[French Academy of Sciences]] and promotion to [[lieutenant]]; and France gained a new, magnificent statue for the [[Louvre]] in Paris.<ref group="note">In fact, the recovery of the Venus de Milo was not the work of Dumont only. Moreover, the French ambassador to Constantinople had already received another report on the discovery of the statue sent by the commander of the ship ''Estafette'' in the [[roadstead]] of Milossome to the French [[Consul (representative)|consul]] to [[İzmir|Smyrna]].</ref>

=== Voyage of ''Coquille'' ===
On his return from the voyage of ''Chevrette'', Dumont was sent to the naval archive, where he encountered Lieutenant [[Louis-Isidore Duperrey]], a past acquaintance.  The two began to plan an expedition of exploration in the Pacific,<ref group="note">Some years earlier Dumont was an unsuccessful candidate to take part in the voyage of the ship ''Uranie'', under the command of [[Louis de Freycinet]]. His failure to gain a place on that voyage became for him a personal issue and influenced his later behaviour.</ref>  an area out of which France had been forced during the [[Napoleonic Wars]].  France considered it might be able to regain some of its losses by taking over part of [[New South Wales]].  On 11 August 1822, the ship [[French ship Astrolabe (1811)|''Coquille'']] sailed from Toulon with the objective of collecting as much scientific and strategic information as possible on the area to which it was dispatched.  Duperrey was named Commander of the expedition because he was four years older than Dumont. Dumont discovered the [[Adélie penguin]], which is named after his wife.<ref>Trathan, P. N., & Ballard, G. (2013). Adélie Penguin. In Borboroglu, P. G., & Boersma, P. D. (Eds.), ''Penguins : Natural history and conservation''. University of Washington Press. p. 37. {{ISBN|978-1-4214-1052-4}}.</ref>

[[René-Primevère Lesson]] travelled on ''Coquille'' as a naval doctor and naturalist. On the return to France in March 1825, Lesson and Dumont brought an imposing collection of animals and plants collected on the [[Falkland Islands]], on the coasts of [[Chile]] and [[Peru]], in the archipelagos of the Pacific and [[New Zealand]], [[New Guinea]], and [[Australia]]. Dumont was now 35 and in poor health.  On board ''Coquille'', he had behaved as a competent official, but disinclined to military discipline and subordination.  On the return to France, Duperrey and Dumont were promoted to [[commander]].{{sfnp|Taillemite|2008|p=243}}

==== Collection ====
On ''Coquille'', Dumont tried to reconcile his responsibilities as second in command with his need to carry out scientific work. He was in charge of carrying out research in the fields of botany and entomology. ''La Coquille'' brought back to France specimens of more than 3,000 species of plants, 400 of which were previously unknown, enriching moreover the [[Muséum national d'histoire naturelle]] in Paris with more than 1,200 specimens of insects, covering 1,100 insect species (including 300 previously unknown species). The scientists [[Georges Cuvier]] and [[François Arago]] analysed the results of his searches and praised Dumont.{{Citation needed|date = April 2016}}

As a botanist and cartographer, Dumont d'Urville left his mark on New Zealand. He gave his name to the genus of seaweeds ''[[Durvillaea]]'', which includes southern bull-kelp; the seaweed ''Grateloupia urvilleana''; the species of grass tree ''Dracophyllum urvilleanum''; the shrub ''Hebe urvilleana'' and the buttercup ''Ranunculus urvilleanus''.<ref name="biog">{{Cite web |last=Taonga |first=New Zealand Ministry for Culture and Heritage Te Manatu |title=Dumont d'Urville, Jules Sébastien César |url=https://teara.govt.nz/en/biographies/1d19/dumont-durville-jules-sebastien-cesar |access-date=2023-01-30 |website=teara.govt.nz |language=en}}</ref>

=== First voyage of ''Astrolabe'' ===
[[File:Vanikoro Perouse Monument-a2317068u.jpg|thumb|Inauguration of the monument erected in honour of [[Jean-François de Galaup, comte de Lapérouse|La Pérouse]], shipwrecked and lost on the island of [[Vanikoro]].]]
Two months after Dumont d'Urville returned on ''La Coquille'', he presented to the Navy Ministry a plan for a new expedition, which he hoped to command, as his relationship with Duperrey had deteriorated.  The proposal was accepted and ''La Coquille'' was renamed the {{ship|French ship|Astrolabe|1811|2}} in honour of one of the ships of [[Jean-François de Galaup, comte de Lapérouse|La Pérouse]], and sailed from Toulon on 22 April 1826, towards the Pacific Ocean, for a circumnavigation of the world that was destined to last nearly three years.

The new ''Astrolabe'' skirted the coast of southern Australia, carried out new relief maps of the [[South Island]] of New Zealand, including improved surveys of the [[Marlborough Sounds]] in which he navigated through the narrow and treacherous [[French Pass]] and mapped [[d'Urville Island]], which [[James Cook]] had mapped as being part of the mainland.

[[File:Durville-Vanikoro-Manevai-2.jpg|thumb|left|Dumont d'Urville's expedition at Vanikoro.]]
''Astrolabe'' sailed up the east coast of the [[North Island]], creating comprehensive coastline maps of New Zealand.<ref name="ESNZA">{{cite web| work=Early shipping in New Zealand waters| title=''Astrolabe''| url=http://www.myancestorsstory.com/shiplist_02.html| access-date=10 November 2013| archive-url=https://web.archive.org/web/20131110020537/http://www.myancestorsstory.com/shiplist_02.html| archive-date=10 November 2013| url-status=dead}}</ref> The ship spent six days in the [[Bay of Islands]] taking on food and water before sailing for [[Tonga]].<ref name="ESNZA"/>

''Astrolabe'' visited [[Fiji]], then Dumont executed the first relief maps of the [[Loyalty Islands]] (part of French [[New Caledonia]]) and explored the coasts of [[New Guinea]]. He identified the site of La Pérouse's shipwreck in [[Vanikoro]] (one of the [[Santa Cruz Islands]], part of the archipelago of the [[Solomon Islands]]) and collected numerous remains of his boats.  The voyage continued with the mapping of part of the [[Caroline Islands]] and the [[Moluccas]]. ''Astrolabe'' returned to Marseille on 25 March 1829, with an impressive load of hydrographical papers and collections of [[zoological]], [[botanical]] and [[mineralogical]] reports, which were destined to strongly influence the scientific analysis of those regions. Following this expedition, he invented the terms Malaisia, ''[[Micronesia]]'' and ''[[Melanesia]]'', distinguishing these Pacific cultures and island groups from [[Polynesia]].

Dumont's health was by now weakened by years of a poor diet.
He suffered from kidney and stomach problems and from intense attacks of gout. During the first thirteen years of their marriage, half of which passed far apart, Adélie and Jules had two sons. The first one died at a young age while his father was aboard ''La Coquille'' and the second, also called Jules, on the return of his father after four years away.

Dumont d'Urville passed a short period with his family before returning to Paris, where he was promoted to captain and he was put in charge of writing the report of his travels.  The five volumes were published at the expense of the French government between 1832 and 1834.  During these years d'Urville, who was already a poor diplomat, became more irascible and rancorous as a result of his gout, and lost the sympathy of the naval leadership.  In his report, he criticised harshly the military structures, his colleagues, the [[French Academy of Sciences]] and even the [[Louis Philippe I|King]] – none of whom, in his opinion, had given the voyage of ''Astrolabe'' due acknowledgment.

In 1835, Dumont was directed to return to Toulon to engage in "down to earth" work and spent two years, marked by mournful events (notably the loss of a daughter from cholera) and happy events (notably the birth of another son, Émile) but with the constant and nearly obsessive thought of a third expedition to the Pacific, analogous to James Cook's third voyage.  He looked again at ''Astrolabe''{{'}}s travel notes, and found a gap in the exploration of Oceania and, in January 1837, he wrote to the Navy Ministry suggesting the opportunity for a new expedition to the Pacific.

=== Second voyage of ''Astrolabe'' ===
[[File:Les Corvettes L'Astrolabe, watercolour by A. Mayer 1838 slnsw.jpg|thumb|left|The Astrolabe and the Zelee caught in Antarctic ice, watercolour by A. Mayer. (1838)]]
King [[Louis Philippe I|Louis Philippe]] approved the plan, but he ordered that the expedition aim for the [[South Pole|South Magnetic Pole]] and to claim it for France; if that was not possible, Dumont's expedition was asked to equal the most southerly latitude of 74°34'S achieved in 1823 by [[James Weddell]]. Thus France became part of the international competition for polar exploration, along with the United States and the United Kingdom.<ref group="note">The first British expedition was the 1839–43 voyage of [[James Clark Ross]] and [[Francis Crozier]]. The first American expedition left in 1838 and was led by [[Charles Wilkes]] after Ross’s 1831 conquest of the [[North magnetic pole]].</ref>

[[File:Dumont d'Urville 1837-1840.svg|thumb|Second voyage of the ''Astrolabe'']]
Dumont was initially unhappy with<!---"spiazzato" (?)---> the modifications made to his proposal. He had little interest in polar exploration and preferred tropical routes.  But soon his vanity took over and he saw the opportunity for achieving a prestigious objective.<ref group="note">At that time national prestige derived from polar exploration in the same way that it is derived from space exploration in recent times.</ref> The two ships, ''Astrolabe'' and ''Zélée'' were prepared for the voyage at Toulon.

==== First contact with Antarctica ====
[[File:Atlas pittoresque pl 020.jpg|thumb|''[[French ship Astrolabe (1811)|Astrolabe]]'' making water on a floe 6 February 1838]]
''Astrolabe'' and ''Zélée'' sailed from Toulon on 7 September 1837, after three weeks of delay compared to Dumont's plans.  His objectives were to reach the most southerly point possible at this time in the [[Weddell Sea]]; to pass through the [[Strait of Magellan]]; to travel up the coast of [[Chile]] in order to head for Oceania with the objective of inspecting the new British colonies in Western Australia; to sail to [[Hobart]]; and to sail to New Zealand to find opportunities for French whalers and to examine places where a [[penal colony]] might be established.  After passing through the [[East Indies]], the mission would have to round the [[Cape of Good Hope]] and return to France.

Early in the voyage, part of the crew was involved in a drunken brawl and arrested in [[Tenerife]]. A short pause was made in [[Rio de Janeiro]] to disembark a sick official. During the first part of the voyage there were also problems of provisioning, particularly rotten meat, which affected the health of the crew. At the end of November, the ships reached the Strait of Magellan.  Dumont thought there was sufficient time to explore the strait for three weeks, taking into account the precise maps drawn by [[Phillip Parker King]] in {{HMS|Beagle}} between 1826 and 1830, before heading south again.

In the Strait of Magellan Dummont surveyed the coast trying to find out the ruins of [[Puerto del Hambre|Ciudad Rey Don Felipe]], a city founded in 1584 as part of a failed [[Spanish colonization attempt of the Strait of Magellan|Spanish colonization attempt]] to control the passage through the strait.<ref name=Martinic>{{cite book |last1=Martinic |first1=Mateo |author-link=Mateo Martinic |date=1977 |title=Historia del Estrecho de Magallanes |language=es |url=http://www.memoriachilena.cl/602/w3-article-10441.html |location=Santiago |publisher=Andrés Bello |pages=120 }}</ref> An expedition report recommended that a [[French colony]] be established at the strait to support future traffic along the route.<ref>Michael Morris, ''The Strait of Magellan'', Martinus Nijhoff Publisher, 1989, {{ISBN|0-7923-0181-1}}, pages 22 and ff.</ref> The strait was eventually [[Chilean takeover of the Strait of Magellan|settled by Chile in 1843]].<ref>{{Cite book |title=A history of the Chilean boundaries |last=Talbott |first=Robert D.|chapter=The Strait of Magellan |publisher=The Iowa State University Press |year=1974 |isbn=0-8138-0305-5 |edition=A Replica |location=|pages=82–84}}</ref>

Two weeks after seeing their first [[iceberg]], ''Astrolabe'' and ''Zélée'' found themselves entangled again in a mass of ice on 1 January 1838.  The same night the [[pack ice]] prevented the ships from continuing to the south. In the next two months Dumont led increasingly desperate attempts to find a passage through the ice so that he could reach the desired latitude. For a while the ships managed to keep to an ice-free channel, but shortly afterwards they became trapped again, after a wind change. Five days of continuous work were necessary in order to open a corridor in the pack ice to free them.

After reaching the [[South Orkney Islands]], the expedition headed directly to the South Shetland Islands and the [[Bransfield Strait]] separating them from Antarctica. In spite of thick fog they located some land only sketched on the maps, which Dumont named ''Terre de Louis-Philippe'' (now called [[Graham Land]]), the [[Joinville Island group]] and ''Rosamel Island'' (now called [[Andersson Island]]).<ref group="note">These were named respectively after the French King; [[François d'Orléans, Prince of Joinville]], son <!--- no evidence that Louis Philippe had a brother of this name---> of the King; and Vice Admiral [[Claude Charles Marie du Campe de Rosamel]], [[List of Naval Ministers of France|French Naval Minister]].</ref>  Conditions on board had rapidly deteriorated: most of the crew had obvious symptoms of scurvy and the main decks were covered by smoke from the ships' fires and bad smells and became unbearable.  At the end of February 1838, Dumont accepted that he was not able to continue further south, and he continued to doubt the actual latitude reached by Weddell. He therefore directed the two ships towards [[Talcahuano]], in Chile, where he established a temporary hospital for the crew members affected by scurvy.<ref group="note">38 cases on ''Zélée'' and 20 on ''Astrolabe''</ref>

==== Pacific ====
During months of exploration in the Pacific, the ship visited many islands in Polynesia. On their arrival in the [[Marquesas Islands]], the crews found ways "to socialise" with the islanders. Dumont's moral conduct was irreproachable, but he provided a highly summarised description of some incidents of their stay in [[Nuku Hiva]] in his reports. During the voyage from the [[East Indies]] to [[Tasmania]] some of the crew were lost to tropical fevers and [[dysentery]] (14 men and 3 officials); but for Dumont the worst moment during the expedition was at [[Valparaíso]], where he received a letter from his wife that informed him of the death of his second son from cholera.  Adélie's sorrowful demand that he return home coincided with a deterioration in his health: Dumont was more and more often hit by attacks of gout and stomach pains.

On 12 December 1839 the two corvettes landed at [[Hobart]], where the sick and the dying were treated. Dumont was received by [[John Franklin]], [[Governor of Tasmania]] and an [[Arctic]] explorer who later perished on the infamous [[Franklin's lost expedition|Franklin Expedition]], from whom he learned that the ships of the American expedition led by [[Charles Wilkes]] were berthed in Sydney waiting to sail south.

Seeing the consistent reduction of the crews, decimated by misfortunes, Dumont expressed his intention to leave this time for the Antarctic with ''Astrolabe'' only, in order to attempt to reach the South Magnetic Pole around longitude 140°. A deeply wounded Captain Jacquinot urged the hiring of a number of replacements (generally deserters from a French [[whaler]] anchored in Hobart) and convinced him to reconsider his intentions; ''Astrolabe'' and ''Zelée'' both left Hobart on 1 January 1840.  Dumont's plan was very simple: to head south, wind conditions permitting.

==== Turning south ====

The first days of the voyage mainly involved the crossing of twenty degrees and a westerly current; on board there were further misfortunes, including the loss of a man. Crossing the 50°S parallel, they experienced unexpected falls in the air and water temperatures. After completing the crossing of the [[Antarctic Convergence]], on 16 January 1840, at 60°S they sighted the first iceberg and two days later the ships found themselves in the middle of a mass of ice.

In the following days the expedition followed the coast westward then led for the first time some experiments to determine the approximate position of the [[South magnetic pole]]. They sighted the American [[schooner]] ''Porpoise'' of the [[United States Exploring Expedition]] commanded by [[Charles Wilkes]] on 30 January 1840, but failed to communicate due to a misunderstanding.<ref name=Stanton>{{cite book|last1=Stanton|first1=William|title=The Great United States Exploring Expedition|date=1975|publisher=University of California Press|location=Berkeley|isbn=0520025571|pages=[https://archive.org/details/greatunitedstate00will/page/176 176-177]|url=https://archive.org/details/greatunitedstate00will/page/176}}</ref> On 1 February, Dumont decided to turn to the north heading for Hobart, which the two ships reached 17 days later.  They were present for the arrival of the two ships of [[James Clark Ross|James Ross]]'s expedition to Antarctica, [[HMS Terror (1813)|HMS ''Terror'']] and [[HMS Erebus (1826)|HMS ''Erebus'']].

On 25 February, the schooners sailed towards the [[Auckland Islands]], where they carried out magnetic measurements and they left a commemorative plate of their visit (as had the commander of ''Porpoise'' previously), in which they announced the discovery of the South Magnetic Pole.<ref group="note">The plate stated, among other things: “"Du 19 Janvier au 1 Février, 1840, découverte de la Terre Adélie et détermination du pole magnétique Austral!” (From 19 January to 1 February 1840, discovered Adélie Land and determined the position of the Southern Magnetic Pole!”</ref>   They returned via New Zealand, the [[Torres Strait]], [[Timor]], [[Réunion]], [[Saint Helena]] and finally Toulon, returning on 6 November 1840, the last French expedition of exploration to sail.

==== Return to France ====
[[File:Voyage au pole sud.jpg|thumb|right|200px|Frontispiece to: ''Voyage au pole sud et dans l'Oceanie'']]

On his return Dumont d'Urville was promoted to [[rear admiral]] and was awarded the [[Gold Medal of the Société de Géographie]] (Geographical Society of Paris), later becoming its president.  He then took over the writing of the report of the expedition, ''Voyage au pôle Sud et dans l'Océanie sur les corvettes l'Astrolabe et la Zélée 1837–1840'', which was published between 1841 and 1854 in 24 volumes, plus seven more volumes with illustrations and maps.

==Death and legacy==
On 8 May 1842, Dumont and his family boarded a train from [[Versailles, Yvelines|Versailles]] to Paris after seeing water games celebrating the king. Near [[Meudon]] the train's [[locomotive]] derailed, the wagons rolled and the [[Tender locomotive|tender]]'s coal ended up on the front of the train and caught fire. Dumont's whole family died in the flames of the first French [[List of accidents and disasters by death toll#Rail accidents and disasters|railway disaster]], generally known as the [[Versailles rail accident]].<ref name="Adams1879">{{Cite web |title=Notes on Railroad Accidents - 1879 |url=http://catskillarchive.com/rrextra/wkbkch06.Html |access-date=2023-01-30 |website=catskillarchive.com}}</ref> Dumont's remains were identified by Pierre-Marie Alexandre Dumoutier, a doctor on board the ''Astrolabe'' and a [[phrenology|phrenologist]].

[[File:Dumont-d'Urville's tombstone.JPG|thumb|Dumont-d'Urville's tombstone in Paris]]

Dumont was buried in the cemetery of [[Montparnasse]] in Paris. This tragedy led to the end of the practice in France of locking passengers in their train compartments.

He is the author of ''The New Zealanders: A story of Austral lands'' – likely to be the first novel written about fictional Maori characters. Later, in honour of his many valuable chartings, the [[D'Urville Sea]] off Antarctica; [[D'Urville Island, Antarctica|D'Urville Island]] in the [[Joinville Island group]] in Antarctica; [[D'Urville Wall]] on the [[David Glacier]] in Antarctica, Cape d'Urville, [[Irian Jaya]], Indonesia; [[Mount D'Urville]], Auckland Island; and [[D'Urville Island]] in New Zealand were named after him. The [[Dumont d'Urville Station]] on Antarctica is also named after him, as is the Rue Dumont d'Urville, a street near the [[Champs-Élysées]] in the [[8th arrondissement of Paris]], and the Lycée Dumont D'Urville in [[Caen]].

Dumont d'Urville himself named [[Pepin Island]] in New Zealand and [[Adélie Land]] in Antarctica after his wife, and Croisilles Harbour for his mother's family.<ref name="biog" /><ref group="note">Some sources state that d'Urville also named [[Adele Island (Australia)|Adele Island]] but this is incorrect (see [[Talk:Jules Dumont d'Urville]]).</ref>

A French naval transport ship employed in French Polynesia is named after him;<ref>{{cite web|url=http://jdb.marine.defense.gouv.fr/batiment/ddv|title=Journaux de Bord – Marine nationale|author=Ne pas utiliser|access-date=6 September 2010|archive-url=https://web.archive.org/web/20101228181316/http://jdb.marine.defense.gouv.fr/batiment/ddv|archive-date=28 December 2010|url-status=dead}}</ref> as was a 1931 [[Sloop-of-war|sloop]] which served in [[World War II]].<ref>{{cite web|url=http://www.netmarine.net/bat/batral/dumont/ancien.htm|title=Aviso colonial Dumont d'Urville|access-date=6 September 2010|archive-url=https://web.archive.org/web/20101004175636/http://www.netmarine.net/bat/batral/dumont/ancien.htm|archive-date=4 October 2010|url-status=dead}}</ref>
