-
Janssen brothers experiment with different sized lenses in a tube. Forerunner of compound microscope.
-
Made microscope and looked at bark of cork tree. Coined the term "cells" when he saw all of the holes in the tree's bark.
-
Performs experiment with meat and flies that disproves spontaneous generation.
-
Antoni Van Leewenhoek created a more powerful telescope than Robert Hooke. He discovered bacteria with a microscope that could zoom in 300x.
-
A naturalist and pastor who exposed soup to air and determined that the microorganisms he found in the soup came from the air.
-
Comes up with general cell theory. Expanded upon and corrected by his fellow scientists who came later.
-
Biologist who added to the discoveries already found by John Needham. Performed another variation of Needham's soup experiment.
-
Unequivocally the first person to discover the nucleus.
-
Suggests that basic structure of animal tissue is uniform sized "globules".
-
Gave the nucleus its name. Also discovered the random motion of molecules.
-
Observed binary fission in plants and found a "perfectly clear explanation for the origin and development of cells"
-
Proposed that "the cell constitutes as basic unit of the organized state, everything is ultimately derived from cells."
-
Theodor Schwann and Matthias Schleiden confirm the presence of cells that was proposed almost 200 years earlier. They also formulated the Cell Theory.
-
Using new knowledge of microscopes and cells, Mendel was able to experiment genetically with pea plants. Known as the "Father of Modern Genetics"
-
Unlike many other microscope inventors and innovators, he was the one who differentiated magnification and clarity, and found the perfect formula for creating microscopes.
-
Discovers mitosis.
-
Louis Pasteur becomes interested in microscopy and partners with Robert Koch. Together they study bacteria.
-
Carl Zeiss creates commercial microscope with double the magnification of Abbe's microscope.
-
Views unstained cells with phase angles of rays. Scoffed at by a scientist who worked at the Zeiss factory. Won Nobel Prize for his discovery.
-
Much more pwoerful than any microscopes used before. Came a long way from the microscopes first used by Schwann to discovery and prove the cell theory.
