Jeanne Villepreux-Power facts for kids
Jeanne Villepreux-Power, born Jeanne Villepreux (24 September 1794 – 25 January 1871), was a pioneering French marine biologist who in 1832 was the first person to create aquaria for experimenting with aquatic organisms. The English biologist Richard Owen referred to her as the "Mother of Aquariophily." She was the inventor of the aquarium and the systematic application of the aquarium to study marine life, which is still used today. In her time as a forefront cephalopods researcher, she proved that the Argonauta argo produces its own shells, as opposed to acquiring them. Villepreux-Power was also a noted dressmaker, author, and conservationist, as well as the first female member of the Catania Accademia Gioenia.
Early life
Villepreux-Power was born in Juillac, Corrèze, on September 24 or 25, 1794, the eldest child of a shoemaker and a seamstress. She lived until age 18 in rural France, where she learned to read and write. With the exception of reading and writing, Jeanne's schooling was fairly basic. They had to live on a strict budget and her mother died when she was eleven years old.
Moving to Paris
At the age of 18, in 1812, she walked to Paris to become a dressmaker, a distance of over 400 kilometres (250 mi). The relative who was designated as her travel guardian assaulted her on the way to Paris and took her identity documents with him. She have to seek refuge in an Orleans police station until she could receive new travel documents.
Due to that delay, her initial opportunity had since been occupied by someone else. She found another opportunity working as a seamstress assistant. She built out and proved her skills many times over, until she became fairly well known.
In 1816, she became well known for creating the wedding gown of Princess Caroline in her wedding to Charles-Ferdinand de Bourbon. She met and married the English merchant James Power in 1818, and she took the surname Villepreux-Power following their marriage. The couple moved to Sicily and settled in Messina where they lived for about 25 years.
Foray into science
It was after moving to Sicily where Jeannette Villepreux-Power took an interest in continuing her education. She began to study geology, archeology, and natural history; in particular she made physical observations and experiments on marine and terrestrial animals. She wanted to inventory the island's ecosystem and did so during frequent walks around the city. She was a self-taught naturalist who explored Sicily, cataloging and commenting on its flora and fauna while gathering examples of minerals, fossils, butterflies, and shells. As she traveled, she would document and collect samples which were later compiled and published in Itinerario della Sicilia riguardante tutti i rami di storia naturale e parecchi di antichità che essa contiene and Guida per la Sicilia.
Villepreux-Power then began to more intently study cephalopods and other marine life and was in need of a vessel that would allow her better access to observation over time of the same marine animals. While land animals could be observed somewhat easily, marine life was distinctly harder to examine. As such, she worked to develop a glass enclosure, ultimately developing three working models to study live marine life in and out of the water. The first was the aquarium as we know it today; the second glass surrounded by a case that was submerged in the ocean; the third an anchored cage also to be submerged in the ocean for larger marine life like mollusks. It was revolutionary at the time as she was the first to record that some species of octopuses could use tools to pry open their prey's shells.
In 1834, a professor, Carmelo Maravigna, wrote in the Giornale Letterario dell’Accademia Gioenia di Catania that Villepreux-Power should be credited with the invention of the aquarium and systematic application of it to the study of marine life. She created three types of aquarium: a glass aquarium for her study, a submersible glass one in a cage, and a cage for larger molluscs that would anchor at sea. Her first book was published in 1839 describing her experiments, called Observations et expériences physiques sur plusieurs animaux marins et terrestres.
Her second book, Guida per la Sicilia, was published in 1842. It has been republished by the Historical Society of Messina. She also studied molluscs and their fossils; in particular she favoured Argonauta argo. At the time, there was uncertainty over whether the Argonaut species produced its own shell, or acquired that of a different organism (similar to hermit crabs). Villepreux-Power's work showed that they do indeed produce their own shells. As a groundbreaking discovery, there was a considerable amount of backlash that she received for her work.
Villepreux-Power was also concerned with conservation, and is credited with developing sustainable aquaculture principles in Sicily. She was among the first to investigate aquaculture as a means of safeguarding and restoring fish and other marine animal populations. Being intrigued also helped to find ideas of aquaculture, which is largely considered a more sustainable food source in the future, specifically through utilizing cages attached to the shore containing fish at different lifecycle stages to generate repopulation opportunities that could be moved to underpopulated rivers.
She was the first woman member of the Catania Accademia Gioenia, and a correspondent member of the London Zoological Society and sixteen other learned societies.
Innovation
She gained admission into prestigious scientific societies after developing one of the most significant experimental tools in marine biological research. One of her most important creations was the first glass aquarium. A critical pain point in the study of marine biology was fulfilled by Villepreux-Power's glass tank. Before it was created, studying marine species presented several difficulties for biologists. The development of marine biology as a scientific field was hampered by the incapacity to efficiently investigate these organisms in their native habitats. This problem was resolved by Villepreux-Power's idea, which helped scientists learn more about the biology and behavior of marine life.
Later, the modern style of glass aquarium was developed by the British biologist Philip Gosse (1810–1888). The first public aquarium opened in London in 1853, and Gosse supplied the units displayed there. Aquaria became popular among the middle classes. Following London, the Berlin Aquarium Unter den Linden (Berlin) opened its doors in 1869, and the Public Aquarium of Trocadero (Paris) opened its doors in 1867.
The invention has evolved into something better and is still in use today. There are already more than 200 marine aquariums and ocean life centers across the globe. The world is seeing an increase in the construction of aquariums, which are now enjoyable destinations for both children and adults to explore. We wouldn't be able to examine and investigate aquatic life more easily without her innovation.
Late life
Since women were not permitted to give talks at academic conferences, enroll in colleges, or work in the scientific community, her results were disseminated around the globe via a proxy. Her research was given to the London Zoological Society on her behalf by Sir Richard Owen, the preeminent scientist in England before Charles Darwin. Throughout her experiments, they had been communicating with one another. In no time at all, it was published in German, French, and English and rapidly dispersed throughout Europe.
Villepreux-Power and her husband left Sicily in 1843, and many of her records and scientific drawings were lost in a shipwreck. Although she continued to write, she conducted no further research. She did, however, become a public speaker. She and husband divided their time between Paris and London. She fled Paris during a siege by the Prussian Army in the winter of 1870, returning to Juilliac. She died in January 1871.
It was not until much later, in 1997, that Jeanne's work was rediscovered after she had been forgotten for more than a century. In 1997 her name, "Villepreux-Power," was given to a crater on Venus discovered by the Magellan probe.
