Microscope was invented
The invention of the microscope was one of the most fundamental and historical moments because without it, scientists would have never discovered cells and come up with the cell theory. -
Period: to
Robert Hooke's Lifespan
Hooke published a book called Micrographia, and it basically explained to other scientists what microscopes could mean in terms of research and how it would help them discover new (and microscopic) things. -
Microorganisms are discovered by Antoni Van Leeuwen-hoek
When Leeuwen-heok discovered the small particles moving under his microscope had signs of life, he wrote a letter explaining the different types of micro-organisms. -
Period: to
Matthias Jakob Schleiden Lifespan
Schleiden discovered that plants also have cells, which contributes to the first theory of cell theory which is that all organisms are made of cells. -
Period: to
Theodor Schwann
Schwann was a zoologist who had also come to the conclusion a year later that animals also have cells, which also related to the firt theory of the cell theory. -
Period: to
Joseph Gerlach Lifespan
Gerlach proposed that nerve cells would branch out and connect to each other, causing nerve fibers to create and make other nerve cells. -
Period: to
Rudolf Virchow Lifespan
Virchow and two other gentlemen back in his time were able to refute the idea that cells appear spontaneously, but instead suggest that cells were derived from other living cells, which supports the third theory in cell theory. -
Robert Brown discovered the nucleus was an important part of the cell
Brown discovered that cells weren't being powered on their own without something to tell it what to do, so with some observations, he found out that cells have a nucleus which is basically the control center of a cell. -
Karl Deiters published a book on nerve cells
Deiters wrote and published a book that shows the readers wonderful and descriptive drawings, and nerve cells under a microscope to show other scientists different nerve cells and showed how they linked to cell theory. -
Oil-Immersion Lens were introduced
The introduction of these new lens had a huge impact on the science community because it allowed them to see new organisms under a microscope much better.
