This is Zacharias Jensen. He was a Dutch spectacle-maker from Middelburg, Holland. He helped out with
inventing the first truly compound microscope with his father Hans Jensen. It started when they put several lenses in a tube and something very interesting happend. When looking at the object at the end of the tube from the other side, the object appeared bigger then the original image,and much more magnifying power than a plain magnifying glass could.
Their first microscopes they made were limited to a magnification power of only 9x (a 3x lens at one and and a 3x lens at the other (3 x 3 = 9), so only had a total magnification of 9x that means the image is 9 times bigger then the original, and the images were somewhat blurry.

This is essentially what the first compound microscope looked like,
A Compound microscope contains two or more lenses connected by a hollow tube, the top lens, what we would look though is called the eye peice, and the bottom, the objective lens. So now, when you hear people say "microscope" they are most likeley talking about a "compound microscope".
