Zacharias Jansen ~ Light Microscopes
In 1638, the light microscope was finished. Light microscopes play an large role in many facilities. They can be used as a primary tool or in support of electron microscopy. -
Robert Hooke ~ Cork Cells
In 1665, Robert Hooke examined a sliver of cork with a microscope. Looking closer, he saw small boxes that reminded him of cells, (like the room,) thus concluding the given title 'cells.' -
Francesco Redi ~ Not Spontaneous at all
In 1668, Francesco Redi tested the hypothesis of spontaneous generation with flies on meat, and disproved it, therefore leading scientists onto the next step of cell theory. -
Anton van Leeuwenhoek ~ Magnification
In 1674, Anton van Leeuwenhoek improved magnification of microscopes by creating his own, one that had powerful magnifying glasses, unlike Jansen's compound microscopes. That's going to be useful later on for development of more microscopes. -
Matthias Schleiden ~ Plants and Cells
In 1838, German botanist Matthias Schleiden concluded all plants were composed mainly of cells which sparked a big wave of interest in the science fields... however he was quite wrong as his theory of spontaneous regeneration was disproved by Mr. Rudolf Virchow. -
Theodor Schwann ~ Assistance in Cell Theory
In 1839, Theodor Schwann made a monograph that applied Schleiden's theory to animals and not just plants.The thought marked a big change in the science and anatomy fields. -
Rudolf Virchow ~ Yes! Cells!
In 1858, Rudolf Virchow concluded that, yes, cells do divide and create other cells, and disproved Schleiden's theory that they just magically appear. This settled things fpr Schleiden and Schwann. -
Cell Theory ~ Concluded and Accepted
In 1858, pretty much everyone had known about the cell theory, and accepted it... well, almost everyone.This is important to understand because cells form the basis of all life, and that's going to be useful in severak job professions to know. -
Louis Pasteur ~ Let There Be Milk (and wine too!)
In 1861, Louis Pasteur pasteurized milk and wine, disproved spontaneous generation of microbes, and discovered several bacteria, leading into a safer future for us. Thanks Louis. -
Max Knoll and Ernst Ruska ~ Let us Actually See Things!
Created in 1932, the electron microscope is a type of microscope that uses a beam of electrons to create an image of the specimen. It is capable of much higher magnifications and has a greater resolving power than a light microscope, allowing it to see much smaller objects in finer detail. ("What Is Electron Microscopy?"
