A guys whose main job wasa cabinet maker! Antoine van leeuwenhoek a dutch cabonmet maker who made the first microscope able to see micro-organisms
these were drawn and described as wee animicules and are pretty good representation of what we see down our microscopes today
The idea of using lenses to magnify objects was about in the 1st century but I think it was the Dutch father and son Zaccharias and Hans Janssen in 1590 who actully made the first compound microscope and then many after this improved it including Galieo, Anthony Leeuwenhoek and Robert Hooke.
In the late 1500s two Dutch spectacle makers Zaccharias and Hans Janseen (father and son) discovered that objects appeard larger when they experimented with certain lenses. The Galileo in the early 1600s followed up on these findings and formulated the first physical principles of lenses.
But Anton van Leeuwenhoek (1632-1723) is widely considered as the discoverer of Microscopy. He was a Dutch scientist who developed new methods of grinding and polishing tiny lenses to increase the curvature and produce bigger magnifications (up to 270 times).
I am using microscopy in my own work. I am using what is known as Atomic Force Microscopy which is a kind of scanning microscopy that allows us to get 3d images of small molecules like DNA and proteins. It is a great technique and has been very useful to me.
