Jeanne Villepreux-Power facts for kids
Jeanne Villepreux-Power (born September 24, 1794 – died January 25, 1871) was a French scientist who loved the ocean. She was a pioneer in marine biology, which is the study of sea life. In 1832, she became the first person to create aquariums to study animals that live in water. An English biologist named Richard Owen even called her the "Mother of Aquariophily," meaning the mother of aquariums!
Jeanne invented the aquarium and showed how useful it was for studying marine life. Scientists still use aquariums today. She also proved that a type of octopus called the Argonauta argo (also known as the paper nautilus) makes its own shell. Before her work, many people thought these creatures found empty shells, like hermit crabs do. Jeanne Villepreux-Power was also a talented dressmaker, a writer, and someone who cared about protecting nature. She was the first woman to join the Catania Accademia Gioenia, a famous science group in Italy.

Early Life and Journey
Jeanne Villepreux was born in Juillac, Corrèze, France. Her father was a shoemaker and her mother was a seamstress. She grew up in the countryside and learned to read and write. Her family lived simply, and her mother passed away when Jeanne was eleven years old.
In 1812, when she was 18, Jeanne decided to move to Paris. This was a long journey, more than 400 kilometers (250 miles) on foot! She faced some difficulties on her journey, losing her travel documents, but she managed to reach Paris.
Life in Paris and Sicily
Jeanne wanted to become a dressmaker. Her first chance to work was taken by someone else because of her travel delay. But she soon found a job as a seamstress assistant. She worked hard and became very skilled and well-known.
In 1816, she became famous for making the wedding dress for Princess Caroline. In 1818, she met and married an English merchant named James Power. After their marriage, she took the name Villepreux-Power. The couple then moved to Sicily, an island in Italy, and lived in Messina for about 25 years.
Discovering Marine Life
Once in Sicily, Jeanne Villepreux-Power became very interested in learning more. She started studying geology (the study of Earth's rocks), archeology (the study of old human history), and natural history (the study of living things). She especially loved observing and experimenting with animals from both land and sea.
Jeanne explored Sicily, carefully listing and describing its plants and animals. She also collected samples of minerals, fossils, butterflies, and shells. She wrote down all her discoveries in books like Itinerario della Sicilia and Guida per la Sicilia.
Inventing the Aquarium
Jeanne then focused on studying cephalopods (like octopuses and squids) and other sea creatures. It was hard to study marine life because you couldn't easily see them over time. Land animals were much easier to watch!
So, Jeanne came up with a brilliant idea: a glass container to hold live sea animals. She developed three different types of these containers:
- The first was the glass aquarium we know today.
- The second was a glass container inside a cage that could be lowered into the ocean.
- The third was a larger cage, also lowered into the ocean, for bigger sea creatures like molluscs.
This invention was revolutionary! She was the first to record that some octopuses could use tools to open the shells of their prey. In 1834, a professor named Carmelo Maravigna wrote that Jeanne Villepreux-Power should be recognized for inventing the aquarium and using it to study marine life.
Her first book about her experiments, called Observations et expériences physiques sur plusieurs animaux marins et terrestres, was published in 1839. Her second book, Guida per la Sicilia, came out in 1842.
The Mystery of the Argonaut Shell
Jeanne also studied molluscs and their fossils, especially the Argonauta argo, also known as the paper nautilus. At that time, scientists weren't sure if the Argonaut made its own shell or found one, like a hermit crab.
Jeanne Villepreux-Power's careful work proved that Argonauts do indeed create their own beautiful, delicate shells. This was a huge discovery, and she faced some criticism for her groundbreaking findings.
Protecting Sea Life
Jeanne Villepreux-Power also cared deeply about protecting nature. She helped develop ideas for sustainable aquaculture in Sicily. Aquaculture is like farming fish and other sea animals. She was one of the first to explore how aquaculture could help protect and bring back fish populations.
She suggested using cages attached to the shore to raise fish at different stages of their lives. These fish could then be moved to rivers where populations were low, helping them grow again. This idea is still important today for creating a more sustainable food source.
Jeanne was the first woman to become a member of the Catania Accademia Gioenia. She was also a corresponding member of the London Zoological Society and many other scientific groups.
The Impact of Her Innovation
Jeanne Villepreux-Power's invention of the glass aquarium was a huge step forward for studying marine biology. Before her invention, it was very difficult for scientists to study sea creatures in their natural homes. Her glass tanks solved this problem, allowing scientists to learn much more about how marine life behaves and lives.
Later, a British biologist named Philip Gosse developed the modern style of glass aquarium. The first public aquarium opened in London in 1853, using tanks supplied by Gosse. Aquariums quickly became popular with people everywhere. Public aquariums opened in Berlin in 1869 and Paris in 1867.
Today, Jeanne's invention has grown into something even better. There are now more than 200 marine aquariums and ocean life centers around the world. These places are fun and educational for both children and adults. We wouldn't be able to explore and learn about aquatic life so easily without her amazing idea!
Later Life and Legacy
In Jeanne's time, women were not allowed to give talks at science conferences or work in many scientific jobs. So, her research was shared with the world by others. Sir Richard Owen, a leading scientist in England, presented her work to the London Zoological Society. Her discoveries were quickly published in German, French, and English, spreading across Europe.
In 1843, Jeanne Villepreux-Power and her husband left Sicily. Sadly, many of her important notes and scientific drawings were lost in a shipwreck. Even though she continued to write, she didn't do any more research after that. She did, however, become a public speaker. She and her husband spent their time between Paris and London.
In the winter of 1870, Jeanne had to leave Paris because of a siege by the Prussian Army. She returned to her hometown of Juillac and passed away in January 1871.
For more than a century, Jeanne's work was largely forgotten. But in 1997, her contributions were rediscovered. To honor her, a crater on the planet Venus, found by the Magellan probe, was named "Villepreux-Power."
