SHE THOUGHT IT

Jeanne Villepreux-Power was a French self-taught pioneer in marine biology and one of the most eminent naturalists of her time2 (p.486), for not only did she invent the aquarium in 1832, but also used this controlled aquatic environment for research purposes; namely, she succeeded in studying aquatic organisms by creating three types of aquaria, while being aware of the importance of repeating the experiments and striving for thorough observation. The types differed depending on the material and the positioning of the aquarium and also on the basis of the size of the observed animal3 (p.144): a glass one that is a forerunner of the modern aquarium was suitable for studying live molluscs indoors; another, also made of glass, was surrounded by a cage and submerged in the sea in order to study small molluscs; for observing larger molluscs, Villepreux-Power invented the third type, named “Power cages” – rectangular wooden cages with four anchors at its corners, that were sunk and anchored at a certain depth in the port of Messina3,4 (p.144 & p.60, resp.). It was possible to haul the cages and glass containers from the sea by means of a specially constructed mechanism that enabled easier observation5 (p.29). Another cage, which was not placed in the sea, but in a house next to it, had an efficient water circulation system that was based on rubber hoses pumping salt water in and out5 (p.29).

Through the systematic use of her invention and numerous experiments, Villepreux-Power was able to precisely describe the morphology and the habits of cephalopods, especially of the pelagic octopus Argonauta argo, also known as Paper Nautilus. She was the first person to answer a question that had the object of conflicting opinions since Antiquity: she discovered that the shell of A. argo was produced by the animal itself and not acquired – which was the predominant opinion at that time – as in the case of the hermit crab. She proved this with an experiment involving the animal’s regeneration of the broken shell from shell pieces6 (p.1243). Moreover, observing the differences between the common octopus (Octopus vulgaris) and A. argo, and the reproduction of the latter7 (p.21–23), she was the first to suggest that the small worm-like organ, which was inserted into the female and considered to be a parasitic worm, was actually related to the male A. argo8.

Among her other scientifically relevant research was her study of the Octopus vulgaris: she described how the octopus uses tools, e.g. stones, to keep the nobel pen shell (Pinna nobilis) open6 (p.1243). Not only was Villepreux-Power’s invention of the aquarium beneficial in terms of research, but she also thought about its applied use as a means for restocking the rivers with fish, and thus established the foundation of aquaculture in Sicily4,9. Young fish would be fed in cages until they would reach a desired size to be consequently released into the formerly depopulated river.

In addition to her specific naturalist experiments and observations, Villepreux-Power presented detailed information about Sicily’s environment in two nature guides and thus documented Sicilian wildlife, landscape and natural heritage in the nineteenth century10. Being confident about the accuracy of her research methods and her many years of experience on the island, she strived to present both guides under an authoritative stance to the Sicilian and Italian audience as well as to the British one11 (p.42).

 

BIOGRAPHY

Even though Villepreux-Power was born in France during the French revolution, the consequences of the Reign of Terror did not reach her, because she grew up the daughter of a cordwainer in Juillac, a village deep in the countryside4,12 (p.59 & p.51, resp.). Unlike her siblings, Jeanne gained a basic education and learnt how to read and write4 (p.59). In 1812, she left for the capital, accompanied by her cousin, who was taking a herd of cows to a slaughterhouse in Paris and who also functioned as a guardian for the underage Villepreux-Power; however, along the way her cousin assaulted her and she was forced to take refuge in the police station in Orléans, where she waited for new documents in order to be able to travel13,14. The workplace she had been promised in Paris had already been taken upon her late arrival, but she nevertheless had the opportunity to work as an assistant to a society seamstress, proving her skills to such an extent that she was entrusted with embroidering the wedding dress for Sicilian princess Marie-Caroline de Bourbon-Sicile, who was marrying Charles Ferdinand d’Artois, Duke of Berry, in 181613,14. Through this commission, Villepreux met noble English merchant Sir James Power, whom she married in 1818 in Messina, Sicily, where they would settle and live for more than twenty years, and where she began to teach herself everything related to natural history and natural sciences4 (p.59).

Her numerous excursions and explorations on foot around Sicily resulted in diverse collections of shells, butterflies, fossils and minerals, as well as detailed descriptions of the island’s cultural and natural environment, its flora and fauna. All that information was published in Itinerario della Sicilia riguardante tutti i rami di storia naturale e parecchi di antichità che essa contiene and Guida per la Sicilia. It was at the port of Messina that she made use of her newly invented aquarium whilst carrying out research on the A. argo which, at that time, was quite common in the waters around Sicily. At the same time, she continued her studies of other molluscs and marine animals. In 1838, the brigantine Bramely, which was supposed to transport Villepreux-Power’s precious collections, drawings and papers to London, sank before reaching its destination13,14. This was particularly unfortunate as her natural history collections, for which she had been interacting with fishermen in order to find the desired specimens6 (p.1243), were considered to be one of the most beautiful in Europe14. Nevertheless, her findings were not completely lost and forgotten due to her published publications, as well as her correspondence with other naturalists, e.g. Richard Owen8.

The Powers lived in Sicily until 184214 and subsequently spent alternate periods of time between the cities of Paris and London13,14. When Paris was under the siege by Prussian forces during the Franco-Prussian War, which led to French defeat, Villepreux-Power escaped and found a retreat in Juillac, where she died in 1871.

 

SCIENTIFIC COLLABORATION AND RECOGNITION

Villepreux-Power became well connected with respected foreign natural scientists who visited Sicily during her stay there6 (p.1243); they knew about her work, and some of them even referred to it (e.g. Wilhelm Peter Eduard Rüppell). Likewise, they knew about her working conditions in Messina3 (p.144). She probably also met Heinrich Müller and Albert von Kölliker, who in 1852 were working on their specialised fields of inquiry for publishing a joint research with Carl Gegenbaur3,6 (p.145 & p.1243, resp.).

In 1835, Villepreux-Power entrusted her findings on A. argo to French malacologist Sander Rang13, who abused her trust by trying to take advantage of her observations and by appropriating some of her discoveries, but he did not succeed since she had already reported them earlier7 (p.27,28). On the other hand, the verity and credibility of Villepreux-Power’s discoveries were doubted by some scientists: Henry de Blainville insisted at the Paris Academy in 1837 that her conclusions regarding the self-producted origin of the A. argo’s shell were false6 (p.1237). However, a few years later, Blainville acknowledged his mistake and published an article on the subject13.

Villepreux-Power was the first female member of the Gioenian Academy of Natural Sciences (Catania, Italy) and was corresponding with English biologist Richard Owen, coiner of the term Dinosauria and founder of the British Museum of Natural History, who, despite his previously mentioned doubts regarding Villepreux-Power’s findings, supported her results and presented them to the Zoological Society of London6 (p.1243) – a scientific institution to which Villepreux-Power was elected as a corresponding member in 183914. Besides this, in 1858, Owen designated her the mother of aquariophily12 (p.52). During her lifetime, she gained membership of various scientific academies throughout Europe12 (p.53), which was a very rare honour for a woman in those times.

 

SHE SAID IT

“(…) I have found it better to verify facts, for I have not studied this marine animal and several others by means of imagination, but by experimental observations. (…)

(…) [F]or ten years, I followed an uninterrupted series, and after repeated attempts, combining and renewing the experiments, I succeeded in obtaining results which led to very useful knowledge, proving that this mollusk is the builder of its shell, clarifying doubts about the first development of its eggs, and taking note of many new facts which relate to its behaviour or habits. (…)

I never thought of giving up my research, even though I saw that my repeated tests did not lead to any satisfactory results. I armed myself with patience and courage, and it was only after several months that I succeeded in clarifying my doubts, and at the same time I saw my research bearing great fruit.” (p.3–7, my translation)

“Finally my methodology is that of a wise naturalist traveller who, wherever she goes, taking the ordered and shortest route, observes, notices, and collects indiscriminately objects belonging to any class or species of natural history, in order to sort them out at her leisure.

I hope that through my work – that has cost me time, effort, and energy – I can please foreign experts in this science as well as Italians. I hope to be of use to foreigners by referring to each type of material by its scientific term, as well as by its popular name; they will thus be able to obtain the objects they desire without leaving their own countries, for, thanks to the use of the popular names, they can even give the task of looking for them to inhabitants of the island who are not experts. As far as Italians are concerned, I reveal to them the extent and variety of the riches with which Nature has endowed their native land, riches which, unfortunately, are unknown to the rest of the population, apart from scientists.” (p.42)

“I have read in several journals that there are a lot of aquaria or cages. (…) [F]rom 1832 to 1842 I worked on them; in 1832 and 1834 I invented several of them which I placed in my house for the studies of the Argonauta and other marine animals, and some that I placed in the sea. I had also invented a glass aquarium for small individuals that I put into a cage laid in the sea.

As I was the first to have the idea of studying marine animals in aquaria or cages, I want to keep my rights as an inventor.” (my translation)

“Madame Jeannette Power is the most beautiful ornament of Messina. With genius, patience and perseverance that seem to be the extraordinary gifts of women, she has written four reports which she has sent to our Gioenian Academy. […]

Mrs. Power, despite so much scientific activity, does not forget the affairs of her house, and she does that so well that she could serve as a model for many mothers. She should be given as an example to put an end to excuses that the majority of women came up with, in order to hide their natural indolence and the lack of education that they have received or that they have not gained.

In most cases, you have to do whatever it takes to be a genius.” (my translation)

PRIZES, ACHIEVEMENTS, HONOURS

Villepreux-Power was unanimously elected corresponding member of the Gioenian Academy in 183515 (p.197), and during her lifetime she became a rare female member of more than twelve scientific academies and institutions15 (p.205), including the Zoological Society of London.

1835: Gabbiole alla Power. Gioenian Academy named invented cages after Villepreux-Power.

1837: Power cages. The Zoological Society of London named the cages after their inventor.

1851: Crustacé Poweri. Linnean Society of London named Phronima sedentaria as Crustacé Poweri in her honour.

1997: Villepreux-Power Patera. The International Astronomical Union named after Villepreux-Power a large crater (patera) on Venus, discovered by the Magellan probe and located at the coordinates latitude 22° South and longitude 210° East.

2010: Roundabout Jeanne Villepreux-Power. The Municipality of Brive-la-Gaillarde named a roundabout between avenue André Emery and street Romain Rolland (near the residential quarter of Prieur) after Jeanne Villepreux-Power. The plaque with the name was also set up.

2011: Jeanne Villepreux-Power prize. President of Récréasciences CCSTI Limousin, Sophie Rémy, created a prize which was intended as encouragement for young girls in the second year of the preparatory classes for scientific studies at the Academy of Limoges. The prize was first given to three laureates in 2011.

2014: Ramp Jeanne Villepreux-Power. The ramp, formerly named Haute-Vienne, that runs alongside the Aquarium of Limousin, was re-named after Villepreux-Power.

 

BRIDGING GAPS

In addition to her scientific work, Villepreux-Power drew over two hundred species of butterflies, caterpillars and chrysalises that she had been observing and studying16. Even though the drawings (as well as other papers) were lost because the ship carrying them sank, it is still possible to admire her watercolour painting of the Argonauta argo from the year 193917.
