Robert Hooke -ANSWER • All living organisms are composed of little boxes or "cells"
• -came up with cell theory - that all microorganisms are made up of cells
-marked the beginning of the cell theory
Anton van Leeuwenhook -ANSWER • 1st cells observed under the microscope
also made the original electron microscope : 10 mil X
Rebecca Lancefield -ANSWER • came up with the system that help classifying different
microorganisms
• it was all based on different polysaccharides in the cell wall
also helped discover Streptococcus pyognes - which is basically strep and we know this
because pyognes is a pus forming microorganism
