Robert Hooke -Correct 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 -Correct Answer • 1st cells observed under the microscope
also made the original electron microscope : 10 mil X
Rebecca Lancefield -Correct 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
Joseph Lister -Correct Answer • discovered phenol: was used to stop surgical would infections
• usually in hospitals : Staphylococcus aures aka staph infection
at least 20% of population is a carrier for the staph infection and they carry it in their noses
Louis Pasteur -Correct Answer • father of microbiology and is the most important scientist in
microbiology
• showed that microbes are responsible for fermentation
• Fermentation: conversion of sugar to alcohol in the absence of air
• Discovered that pasteurization was something that could stop food spoilage
