# The Origins of Oceanography in France

## THE SCIENTIFIC EXPEDITIONS OF TRAVAILLEUR AND TALISMAN (1880–1883)

By John R. Dolan

**ABSTRACT.** This article describes the earliest French oceanographic expeditions dedicated to investigating the deep sea. Though these expeditions, conducted from 1880 to 1883, were quite successful in terms of both science and what today we call “outreach,” they are often overlooked in histories of oceanography or mentioned only in passing. They produced a substantial literature of over 100 scientific publications. Participants’ descriptions of 176 new species are still considered valid today. Among the remarkable scientific discoveries were culturable and pressure-tolerant bacteria in deep-sea sediment samples, which led to the origin of deep-sea microbiology, and iconic deep-sea fish such as the gulper eel. Specimens, instruments, and equipment from these expeditions were on display for the general public at an exhibition at the National Museum of Natural History in Paris in early 1884. Between 1885 and 1891, expedition scientists authored three mass-market books on deep-sea life and the expeditions. Following a summary of the expeditions and their results, some speculation is provided as to why such an auspicious nineteenth century beginning of oceanography in France did not lead to a sustained interest in oceanography. A supplementary file contains a bibliography of expedition publications and a list of the species described from expedition collections.

### THE BEGINNINGS OF SCIENTIFIC STUDY OF THE DEEP SEA
Development of Scientific Interest in the Deep Sea and British Efforts

Histories of scientific interest in the deep sea often, and curiously, give prominence to a proposition credited to Edward Forbes (1844) that the deep sea was a vast lifeless, or azoic, zone (e.g., Rice et al., 1976). In reality, Forbes reported findings only with regard to the vertical distribution of mollusks and echinoderms in the Aegean Sea based on dredging. He found nothing below a depth of 230 fathoms (420 m), and his report included a diagram of faunal depth zones that labeled the layer below 300 fathoms “Zero of Animal Life probably about 300 fathoms.” He did not propose the depth as a general rule, nor did he use the term “azoic”; it appears only once in passing in the posthumously published book, *The Natural History of the European*

Seas (Forbes and Godwin-Austen, 1859, pg. 247). Regardless, testing the idea that no life existed at great depths, despite long-standing but scattered evidence to the contrary (as summarized in Carpenter, 1868), provided a marvelous straw man that justified early explorations for deep-sea life. Additionally, there was great interest in the nature of the seabed and physical conditions in the deep sea as attempts were being made to lay undersea telegraph cables. In fact, some of the early discoveries of deep-sea life forms were made through soundings carried out to determine the depth and nature of the seabed in the North Atlantic by the British (e.g., Wallich, 1860) and during retrieval of broken cables in the Mediterranean by the French (e.g., Milne Edwards, 1861).

The proposition of the deep sea as perhaps azoic provided in no small part the justification for the first systematic explorations of the deep sea led by British biolo-

gists through the expeditions of *Lightning* in 1868 and *Porcupine* in 1869 in the North Atlantic (Thomson, 1873). These first cruises dedicated to dredging the deep sea yielded the conclusions below, presented to the Royal Society of London by William Carpenter, vice president of the society (Carpenter et al., 1870):

1. *That the Ocean bottom, at depths of 500 fathoms or more, presents a vast field for research, of which the systematic exploration can scarcely fail to yield results of the highest interest and importance, in regard alike to Physical, Biological, and Geological Science.*

2. *That the prosecution of such a systematic exploration is altogether beyond the reach of private enterprise, requiring means and appliances which can only be furnished by Government.*

These observations led directly to the first large-scale exploration of the sea, the well-known *Challenger* Expedition of 1872–1876. Preliminary results of the *Challenger* Expedition appeared relatively quickly and were made widely available in 1878 by the chief scientist, Sir Charles Wyville Thomson, in two volumes under the title *The Voyage of the Challenger: The Atlantic: a preliminary account of the general results of the exploring voyage of the H.M.S. Challenger during 1873 and the early part of the year 1876*. The complete scientific results were eventually published from 1885 to 1895 in the famous massive series of over 80 monographs, mostly under the guidance of John Murray following Thomson's death in 1882.
## French Interest in Exploring the Deep Sea

Long-standing French interest in the deep sea is evidenced by Alphonse Milne Edwards's descriptions of organisms attached to the undersea telegraph cables laid between Sardinia and Algeria (Milne Edwards, 1861). In 1867, while Carpenter and Thomson were occupied with planning the *Lightning* expedition, the Marquis Léopold Folin, harbormaster of the Port of Bayonne, founded the first serial publication dedicated to marine sciences, including one focused on the deep sea: *Les Fonds de la Mer (The Bottom of the Sea)*. A naturalist as well as a harbormaster, Folin specialized in tube-forming mollusks on which he would later contribute to the *Challenger* Reports (Folin, 1886).

Les Fonds de la Mer was originally printed in 16-page issues of text with plates (Figure 1). The first “volume,” composed of issues published from 1867 to 1872, contained contributions by George S. Brady, who would later contribute to the Challenger Reports (Brady, 1880), and Alphonse Milne Edwards, whose interests included mammals, birds, and crustaceans and who (along with Folin) would later be responsible for the Travailleur and Talisman expeditions. The first issues also contained early citizen science, as Folin reported extensively on diverse samples of deep-sea soundings and sediment types from around the globe sent to him or delivered by the captains or officers of ships, many traveling to or from Bayonne. Issues of the Les Fonds de la Mer appeared irregularly, with the last issues delivered in 1887. While this first marine science serial is very nearly forgotten, it shows that some French scientists had a marked interest in the deep sea well before the Challenger Expedition, and that they maintained close relationships with British scientists who would later be involved in analyzing samples from Challenger.

Since Thomson's book on the preliminary results of Challenger appeared in 1878, it is plausible, and even probable,

that the success of the British Challenger Expedition prompted, at least in part, Alphonse Milne Edwards to plead in Paris before the Academy of Sciences in 1880 for French expeditions, at the behest of Folin. Milne Edwards had been elected to the academy only the year before at the relatively young age of 43. He successfully argued for government financing for deep-sea expeditions (Milne Edwards, 1881), as many deep-sea expeditions had been carried out in recent years but none in waters near France or by the French, except for private efforts by himself and Folin. With the support of the Academy of Sciences (roughly the French equivalent of the British Royal Society of London), the Ministry of Education named a commission to organize expeditions to explore the deep sea, headed by invertebrate zoologist Henri Milne-Edwards, and including his son Alphonse, Folin, a number of French zoologists, and also the British scientists John Gwyn Jeffreys (who had been

chief scientist aboard Porcupine in 1869) and Alfred Norman. Folin and Alphonse Milne Edwards (Figure 2) obtained the use of a navy steamer, Travailleur, from the Ministry of Maritime Affairs for an expedition to sample the deep sea.

THE EXPEDITIONS OF
TRAVAILLEUR AND TALISMAN

Travailleur was a 45 m long side-wheel steamer (Figure 3a), usually with a crew of about 90, but increased to 128 for the anticipated intensive dredging operations. The dredge used was that designed by the American naturalist Alexander Agassiz: it worked equally well whichever way it fell onto the seabed. The first expedition of two weeks duration in July of 1880 in the Bay of Biscay was basically a shakedown cruise. With 23 dredge hauls made between 300 m and 2,600 m depth, and 103 soundings, the cruise was a resounding success. Preliminary reports by the two British naturalists aboard Travailleur, Jeffreys and Norman, appeared very quickly, noting findings of new deep-sea forms and even some mollusks thought to be extinct (Jeffreys, 1880; Norman, 1880).

Based on the success of the first cruise, eight weeks of ship time was granted for the following year to explore the depths of the North Atlantic and the Mediterranean. During the second *Travailleur* expedition in July and August of 1881, the ship, equipped with 15 km of cable for dredging and new samplers for taking discrete depth water samples, traveled from Bayonne on the Atlantic coast to the Mediterranean. Mostly sampling in the Northwest Mediterranean Sea (see Figure 3b), about 50 deepwater dredge hauls were made; the Mediterranean fauna was found to be largely a subset of that known from the depths of the Atlantic, where the deepwater fauna appeared to be much richer. Again, the preliminary scientific results were described as unique and significant (Milne-Edwards, 1882), justifying continuing the explorations the following year.

The third *Travailleur* cruise lasted the entire months of July and August of 1882 and was dedicated to exploration of the seafloor in the North Atlantic between Bayonne and the islands of Madeira and the Canaries, thus ranging much further offshore than the previous cruises. Dredge hauls were made at 71 stations, again

bringing up new species. The ship, however, with its limited range, proved to be less than ideal for open-water sampling. The final expedition the following year therefore employed a larger steamer with a longer range of operation, *Talisman*.

*Talisman* (**Figure 3c**) was a 75 m long vessel equipped with a steam-driven propeller as well a full complement of sails. It sailed from Rochefort (see **Figure 3b**) on June 1 and returned on August 31, 1883. Sampling was conducted along the Atlantic coasts of Morocco, Sudan, and Senegal, then through the Canaries, the Azores, and out to the edge of the Sargasso Sea. Along the cruise track, 212 soundings and 156 dredge hauls were carried out, some to depths of 5 km. This last cruise with *Talisman* yielded some of the more spectacular finds such as the iconic deep-sea fish, the gulper eel, and decapod crustaceans with odd morphologies, one named after *Talisman* (**Figure 4**). Jeffreys (1884) reported on the *Talisman* cruise, and the participants were honored by the Academy of Sciences with medals of honor. A popular account of the expedition by Filhol was serialized in the French journal *La Nature* (Filhol, 1884); excerpts were translated into English and published in installments in the American journal *Science* (Anonymous, 1884a).

## SUMMARY OF THE SCIENTIFIC RESULTS OF THE TRAVAILLEUR AND TALISMAN EXPEDITIONS

Many new species were described from the material gathered during the expeditions. However, as is often the case, most forms described as new eventually turned out to have been previously described under another name. For example, in his monographic treatment of mollusks from the expeditions, Locard (1897–1898) described 163 forms as new, and of those, only 56 are currently credited as valid original descriptions. Likewise, only 7 of the 70 species of bryozoans described as new by Calvet (1906) are currently credited to him. Nonetheless, a large number, at least 176 species descriptions based on expedition material, are still recognized

as valid. This estimate is conservative as it is not always clear from the descriptions if the specimens used were from the expeditions or from other collections (e.g., Milne Edwards and Bouvier, 1900). Most of the new forms found were benthic macrofauna, shelled mollusks, echinoderms, and crustaceans (**Figure 5**).

A substantial literature concerning the expeditions themselves, or the material collected, was produced totaling at least 126 works. It is probable that my

searches did not uncover all the publications, but of those found, almost half concern the benthic megafauna, mirroring to a large extent the descriptions of new species (**Figure 5**). In addition, there were also technical accounts: cruise narratives destined for a professional audience (e.g., geographers) and official cruise accounts (e.g., for the Maritime Ministry). The most cited publications (according to Google Scholar) are those on the taxonomic groups, with many new

species described, again mollusks and
crustaceans. Exceptions are well-cited
publications that describe bacteria cul-
tured from deep Mediterranean Sea sed-
iment samples collected during the 1881
*Travailleur* expedition and early experi-
ments examining the tolerance of a variety
of microbes for high pressure, like that of
the deep sea. The papers by Adrian Certes
(1884a,b; Certes and Cochin 1884), based
on work he carried out in the laboratory
of Louis Pasteur, are well recognized as
the beginnings of deep-sea microbiology
(e.g., Zobell, 1952; Jannasch and Taylor,
1984; Levin and Gooday, 2003; Bartlett,

2008; Adler and Drucker, 2018). Thus,
ironically, the scientific results of the
expeditions of *Travailleur* and *Talisman*
likely are better known to microbiologists
than to oceanographers.

POPULARIZATION OF THE
DEEP SEA BY EXPEDITION
PARTICIPANTS

Just a few months after *Talisman* returned
to its homeport of La Rochelle, a large pub-
lic exhibition was installed in the National
Museum of Natural History in Paris:
*L'Exposition Sous-Marine du Travailleur
et du Talisman* (The Undersea Exhibition

of the *Travailleur* and *Talisman*). Organized by Milne Edwards with other staff of the museum's Laboratory of Zoological Anatomy and Physiology, the exhibition was opened with great ceremony by the Minister of Education in the company of a variety of politicians and the captains of both *Travailleur* and *Talisman*, as well as all the museum professors (Anonymous, 1884b). From January to March 1884, the public was invited to admire not only specimens of the odd fauna found but also to examine for themselves some of the instruments and equipment used to explore the deep sea (Figure 6). The exhibit was enormously successful, described as drawing crowds not previously seen at the museum (Lacroix, 1926). The exhibition appears to be one of the earliest efforts of outreach in oceanography.

In addition to the exhibition, the expe-
dition participants also wrote books,
aimed at general audiences, about the
deep sea in general and the expeditions in
particular. The first and most spectacular
to appear, as it included four color plates
(e.g., **Figure 7**), was by Henry Filhol in
1885, *La Vie au Fonds Des Mer: Les explo-
rations sous-marines et les voyages du
Travailleur et du Talisman* (Life at the
bottom of the sea: The under-sea explo-
rations and voyages of the *Travailleur*

The exhibition included specimens and illustrations of deep-sea fauna as well as, importantly, the equipment and instruments used in oceanographic studies. Thus, the exhibit displayed not only the deep-sea creatures found but also how the creatures were found. *Illustrations from Filhol, 1884, and Dollo, 1891*</figcaption></figure>
and of the *Talisman*). Henry Filhol would later hold the Chair of Comparative Anatomy at the Museum of Natural History and be elected to the French Academy of Sciences.

The second book, by Edmond Perrier, subsequently to become the director of the National Museum of Natural History, was published a year later, in 1886. From its title, *Les Explorations Sous-Marin* (Undersea Explorations), the book was clearly not focused exclusively on the *Travailleur* and *Talisman* expeditions nor on the deep sea. But, as noted in the preface, Perrier relied considerably on the expeditions' results and the contributions of other cruise participants, including both Folin and Filhol. Second and third editions were published in 1891 and 1899 (Perrier, 1891, 1899). The third popular book appeared in 1887: *Sous les Mers: Campagnes d'explorations du Travailleur et du Talisman* (Under the Sea: The campaigns of exploration of the *Travailleur* and of the *Talisman*) by the instigator of the expeditions, Léopold Folin. By then age 70, Folin dedicated the book to his grandson "hoping he also will be interested in the study of the sea" (Folin, 1887). The fact that these books appeared in such quick succession (i.e., 1885, 1886, 1887, 1891, and 1899) suggests that the publishers found a solid market for popular books on the deep sea.

## NEGLECT OF THE EXPEDITIONS DUE TO THE SLOW DEVELOPMENT OF OCEANOGRAPHY IN FRANCE?

The *Travailleur* and *Talisman* expeditions were scientific and public relations successes, an auspicious beginning to oceanography in France. However, with the singular exception of Saldanha (2002), in accounts of the history of oceanography, they are either mentioned only in passing (e.g., Deacon, 1971; Menzies et al., 1973) or neglected (e.g., Wüst, 1964; Sears and Merriman, 1980) as pointed out by Mills (1983). This is likely due, at least in part, to the fact that the expeditions were not followed by sustained

development of oceanography in France. This was largely true until the 1960s. This is not to say that there were no French oceanographic expeditions; there were, for example, the early twentieth century voyages of Jean-Baptist Charcot to the Arctic and Antarctic, but they were conducted without the direct support of governmental agencies (Laubier, 1992). Meanwhile in other countries, such as the United States, Germany, and the United Kingdom, oceanography grew

rapidly in the first half of the twentieth century with the establishment by the 1930s of oceanographic institutions and graduate programs in oceanography (Vaughn, 1937). Admittedly, assessing why oceanography failed to develop similarly in France is largely speculation. Nonetheless, a few non-exclusive explanations can be offered.

One factor may have been a lack of scientists of stature advocating for oceanography. The instigators of the expedi-

<figure><img src="image_13.png" /><figcaption>**FIGURE 7.** Plate 2 of *La Vie au Fonds des Mer: Les explorations sous-marines et les voyages du Travailleur et du Talisman* (Life at the bottom of the sea: The undersea explorations and voyages of the *Travailleur* and of the *Talisman*; Filhol, 1885) depicts organisms from depths between 1,000 m and 1,500 m.</figcaption></figure>
tions, Folin and Milne Edwards, both
died by 1900. Although the other scien-
tists involved eventually acquired con-
siderable stature, they were classic zool-
ogists working on a variety of taxa and
not focused on studies of the sea. There
were no French personalities comparable
to John Murray in the United Kingdom,
Alexander Agassiz in the United States,
Johan Schmidt in Denmark, or Victor
Hensen in Germany. Another possible
factor is that the oceanographic institute
created by the Prince of Monaco in Paris,
along with his voyages (which furnished
specimens for researchers in France),
reduced impetus and need for the estab-
lishment of a French oceanographic insti-
tution. Ironically, the Prince of Monaco
is said to have been greatly inspired to
create the Musée Océanographique in
Monaco by the *Travailleur* and *Talisman*
exhibition at the National Museum of
Natural History (Carpine-Lancre, 2001).
The Institute Océanographique in Paris
employed some research staff, and classes
were given, but it did not confer diplomas.

Another aspect is that marine science
in France was, by the early 1900s, over-
whelmingly dominated by marine biol-
ogists working on littoral habitats in a
large number of marine stations, part
of what Anthony Adler (2019) termed
“The Marine Station Movement.” Charles
Kofoid’s 1910 book, *The Biological
Stations of Europe*, listed 14 marine sta-
tions in France (excluding fisheries labo-
ratories) compared to eight in the United
Kingdom and only three in Germany.
Thus, in France, there was a relatively
large population of shore-based biol-
ogists perhaps nearly monopolizing
available resources. Eric Mills (2009)
discussed “the failure of French oceanog-
raphy” and pointed out that for a variety
of reasons, French physical oceanogra-
phers in the early 1900s were few in num-
ber and appear to have been isolated from
scientific currents in other countries.
Regardless of the reasons, oceanography,
although today quite strong, was undeni-
ably slow to develop in France.

The first French vessel specifically

built for deepwater oceanographic work
was *Président Théodore Tissier* in 1933
(Le Danois, 1948), but by 1938 it was
transferred to the merchant marine for
use as a training vessel. In the Cold War
era, the strong ties of ocean scientists with
the navy that characterized the devel-
opment of oceanography in the United
States (i.e., the Office of Naval Research)
apparently did not exist in France. It was
not until 1968 that another deepwater
oceanographic vessel, *Jean Charcot*, was
launched; the vessel was described as
“designed with the ambition of allowing
our country to recover its place among
the leading nations of oceanography”
(Laubier, 1985). Some of the first ocean-
ographic campaigns of both *Président
Théodore Tissier* and *Jean Charcot* were
dedicated to sampling the benthos of
the Bay of Biscay (Le Danois, 1948;
Laubier, 1985) as was the first expedi-
tion of *Travailleur*. Although courses in
ocean sciences were offered in the uni-
versities, degree programs were not cre-
ated in France until the late 1960s, at
about the same time that the national sci-
ence organization, the Centre National
de la Recherche Scientifique (the larg-
est employer of research scientists in
France), formally recognized oceanog-
raphy as a distinct scientific discipline
(Geistdoerfer, 2015).

CONCLUSION

On the heels of the *Challenger* Expedition,
the early French deep-sea explorations of
*Travailleur* and *Talisman*, while not of
the same magnitude as the *Challenger*
Expedition, uncovered a large number
of novel organisms, including the first
deep-sea bacteria and the ever-pop-
ular gulper eel (e.g., https://www.youtube.
com/watch?v=iT_EMKl2A3Y). The sci-
entists involved in the explorations pro-
duced not only a considerable number
of scientific publications, many still cited
today, but also a museum exhibition, arti-
cles in the popular press, and several gen-
eral audience books, all on the deep sea.
Despite their scientific and popular suc-
cesses, the *Travailleur* and *Talisman* voy-

ages are rarely remembered. I hope that,
with the story told here of the remark-
able expeditions of Léopold Folin and
Alphonse Milne Edwards, they will per-
haps be less neglected. ®
