Scanning Tunneling Microscope

In 1981, Gerd Binnig an Heinrich Rohrer invent the scanning tunneling microscope that gives three-dementional images of objects down to the atomic level. This helped us advance and see the atomic level in objects.


Electron Microscope

In 1942, the electron microscope is starting to evolve and is used to identify and characterize a bacteriophage. A bacteriophage is a virus that infects bacteria. This helped us learn more about bacteria.

Ernst Ruska

In 1931, Ernst Ruska starts building the first electron microscope. This helped resolve the problem of damaged specimen from the heat of the microscope.

The Nucleus of the Cell

In 1833, the cell nucleus is discovered with the help of the microscope. This gave us more information about cells.

Joseph Jackson Lister

In 1830, Joseph Jackson Lister reduces the "chromatic effect"so that the image wasn't blurred. This gave us a clearer look at the object you would be magnifying.

Anton Van Leeuwenhoek

In 1674, Anton Van Leeuwenhoek built a simple microscope with a lens to look at blood, yeast, insects, and tiny objects. He was the first person to describe bacteria and he came up with new ways to polish microscopes. This helped us understand bacteria and was the start to finding vaccines for some viruses.

Cells are described!

In 1663, cells are first describe using this type of microscope. This opened our eyes to the world of cells.
