The First Microscope
In 1590 dutch lens maker Zacharias Jansenn built the first microscope which viewed objects about 20 to 30 times bigger. It could see tiny plants insects and small animals that are to small to see with your eyes. -
Robert Hooke
In 1665 Robert Hook looked at a silver cork through a microscope lens and noticed some "pores" or "cells" in it.
Robert Hooke also published micrographia. This is a book describing microscopic and telescopic observations. Later Robert discovered the cell. -
Antony Von Leewenhoek
Around 1668 Van Leewenhoek learned to grind lenses, made simple microscopes and observed them. His microscope enabled him to see single celled organisms.He is also the first person to observe bacteria and protozoa. -
Theodor Schwann
In 1839 Theodor Schwann concluded both animals and plants are made up of cells, this observation was added to the cell theory along with Mathias Schleiden. -
Matthias Schleiden
Matthias Schleiden is the co founder of a part of the cell theory. Matthias first discovered that plants are made up of cells, later Theodor Schwann added to his theory. -
The Cell Theory
Rodolf Virchow was the last person to add onto the 4 main points of the cell theory . This theory states if something is living or not. -All living things are composed of cells
-All cells come from pre existing cells
-The well being of an organism depends on the well being of it's cell
-Cells are the basic building units of life -
The Ultramicroscope
In 1903 Richard Zsigmondy developed the ultramicroscope. This microscope can study objects below the wavelength of light. -
The Electron Microscope
The electron microscope was first founded by Germans, Max Knoll and Ernst Ruska in 1931. It depends on electrons rather than light to view an object. The electron microscope can view objects as small as a diameter of an atom. -
Scanning Tunneling Microscope
In 1981 Gerd Binnig and Heinrich Rohrer invented the scanning tunneling microscope that gives three-dimensional images of objects down to the atomic level.The powerful scanning tunneling microscope is the strongest microscope to date. -
Rodolf Virchow
Rodolf's greatest accomplishment was his observation that the whole organism does not get sick, only certain cells or groups of cells. Rodolf also discovered cells inside bones and connective tissues.
