Carolus Linnaeus lived from 1707 to 1778. He became famous for his way grouping and naming living things.
In Europe in the 1700s, people were discovering more and more of the world.
They were finding out about lots of new plants and animals.
Just naming them all was a big problem. People just made up names by themselves.
There were lots of problems when they wanted to write about them and talk about them.
Linnaeus thought of a way of naming living things that everybody started to use.
