Jeanne Villepreux-Power: The inventor of the aquarium and pioneer of marine biology
Jeanne Villepreux-Power (1799–1870) was a French naturalist and marine biologist, renowned for inventing the modern aquarium in 1832, a tool that forever transformed the study of marine organisms. Thanks to her ingenuity and determination, she made it possible to observe the behavior and reproduction of aquatic species under controlled conditions, laying the foundation for experimental marine biology.
Born in Juillac, France, she began her professional life as a dressmaker in Paris, where she achieved some recognition before moving to Sicily after her marriage to the merchant James Power. There, surrounded by the natural richness of the Mediterranean, she developed a deep curiosity for marine organisms and decided to dedicate herself to the direct study of life under the sea, something practically unexplored in her time.
Aware of the limitations of coastal observation, Villepreux-Power designed three types of pioneering aquariums: a glass one for domestic use, a mixed glass and wood one suitable for boats, and a large submersible box connected to the sea by nets, which allowed her to preserve organisms in their natural environment under experimental conditions. These innovations allowed her to observe biological processes with a rigor that was impossible to achieve with only captured specimens.
One of her most notable studies was on the argonaut argo, a cephalopod mollusk that had intrigued naturalists for centuries. Some believed that the argonaut parasitized shells of other animals, but Jeanne demonstrated through direct observation that the animal itself produces its shell, resolving a scientific controversy that dated back to Aristotle.
In addition, she researched the reproduction of mollusks and proposed early aquaculture methods, suggesting the use of controlled structures to protect and repopulate species in rivers and coastal areas, an idea that was almost a century ahead of modern fisheries management practices.
Although part of her scientific collection was lost in a shipwreck in 1843, her work was recognized by institutions such as the Catania Academy of Sciences and the Zoological Society of London, making her an honorary member. Her legacy survived as an example of experimental rigor, creativity, and determination in an era when science was almost exclusively male.
