Even before microorganisms were seen, some investigators suspected their existence and responsibility for disease. Amongm others, the Roman philosopher Lucretius (about 98-55 B.C.) and the physician Girolamo Fracastoro (1478-1553) suggested that disease was caused by invisible living creatures. The earliest microscopic observations appear to have been made between 1625 and 1630 on bees and weevils by the Italian Francesco Stelluti, using a microscope probably supplied by Galileo. However, the first person to observe and describe microorganisms accurately was the amateur microscopist Antony van Leeuwenhoek (1632-1723) of Delft, Holland.
Robert Hooke was the first scientist to describe cells seen through a microscope. He examined a piece of cork and described what he saw as little "rooms" or "cells" in the specimen.
The first one to have reported studying it was Anthoni van Leeuwenhoek in the 1670's.

Microscope. A scientist might use a microscope. Well actually, it depends on the size of the animal. If it is microscopic, then scientists might have to observe it using it using a microscope. If it can actually be seen, then scientists mught actually take a sample of it back to the labratory to observe physically.
A scientist would likely use a compound light microscope to observe a living one-celled organism. This microscope uses visible light to illuminate the specimen and allows for observing living organisms in real-time. Additionally, a phase contrast or differential interference contrast microscope could also be used to enhance the contrast of the specimen without staining.
In 1864, Louis Pasteur, a French scientist, designed a flask that had a long curved neck to allow air, but not microorganisms, to enter the flask. To observe a small living organism, a scientist might use a compound light microscope.
The simple microscope was invented by Dutch scientist Antonie van Leeuwenhoek in the late 17th century. He used his handcrafted lenses to observe minute living organisms, revolutionizing the field of microscopy.

A compound light microscope is typically used to observe small living organisms in a lab. These microscopes use light to illuminate the specimen and allow for magnification and visualization of the organism's structures.

A light microscope allows scientists to view cells, tissues, and microorganisms at the cellular and subcellular level. This tool enables researchers to observe biological structures and processes in detail, aiding in their study of living organisms.

For viewing a small living cell, an electron microscope would be more suitable as it provides higher resolution necessary to see detailed structures within the cell such as organelles. Compound light microscopes may not have enough magnification power to observe these structures in depth without damaging the cell.
