Jeanne Villepreux-Power was a marine biologist who created the first aquarium in 1832. She was observing and experimenting with aquatic organisms and for that, she needed to keep them somewhere. Villepreux-Power created three types of aquaria. The first one was a glass aquarium to study the marine life, another was a glass apparatus placed within a cage for use in shallow water, and the third was another cage-like aquarium capable of lowering its contents to various depths. By using the aquarium, the biologist was able to discover that Argonauta Argo produces its own shell rather than obtaining it from other organisms.
