Anton Van Leeuwenhoek
He is best known for his work on the improvement of the microscope and for his contributions towards the establishment of microbiology. Using his handcrafted microscopes, he was the first to observe and describe single-celled organisms, which he originally referred to as animalcules, and which are now referred to as microorganisms. He was also the first to record microscopic observations of muscle fibers, bacteria, spermatozoa, and blood flow in capillaries (small blood vessels). Van Leeuwenhoek -

The English physicist Robert Hooke looked at a sliver of cork through a microscope lens and noticed some "pores" or "cells" in it -
Matthias Schleiden

Theodor Schwaan
His many contributions to biology include the development of cell theory, the discovery of Schwann cells in the peripheral nervous system, the discovery and study of pepsin, the discovery of the organic nature of yeast, and the invention of the term metabolism. -

Ernst Ruska
The German engineer Ernst August Friedrich Ruska (1906-1988) designed and built the first electron microscope, for which he was awarded the Nobel Prize in Physics in 1986. The electron microscope, like many other complex technological developments based upon current scientific research, cannot be associated exclusively with a single inventor. In the early 1930s several laboratories were at work on a super-microscope that would use electron waves, instead of light waves, to magnify a microscopic
