Re: who is the first biologist found the amoeba

According to 
this History of Microbiology website,  the famous biologist Anton van 
Leeuwenhoek  first discovered Amoeba:

"1670's ------------------ Anton van Leeuwenhoek lived in the Netherlands 
and was the owner of a dry goods business. He had a natural curiosity for 
examining things that could not be seen with the naked eye. He observed 
hair fibers, skin scaled, eye lenses, blood cells, feces and sperm cells. 
He documented his findings and submitted a letter to the Royal Society of 
London with detailed drawings of what he saw. He discovered 
Animalcules, tiny micro organisms in pond water today known as 
Paramecium and Amoeba."
