Anton van Leeuwenhoek, (October 24, 1632 -- August 26, 1723) is known as "the Father of Microbiology". He was from Delft, Netherlands. He was not trained in science, but was originally a tradesman.

Around 1670, more than half a century after the discovery of the microscope, van Leeuwenhoek discovered a way to make small lenses of very high magnification that went significantly beyond the capability of existing microscopes.

He is considered to be the first microbiologist because of his scientific discoveries made possible by his improvement of the microscope. He was the first person to observe and describe single celled organisms. He was a contemporary of Robert Hook and the two men share some credit for establishing that living things were made of cells.

Beyond the initial discovery of the method for making small spherical lenses, van Leeuwenhoek built a hundreds of microscopes and experimented with their design.

Answer 3

The first drop glass microscope that was far superior to anything else made at the time. Unfortunately, Leeuwenhoek took this secret process to his grave and this process was not rediscovered for hundreds of years.
