what did he do

• Koch proved Pasteur was right - that germs were the cause of disease and decay. His main achievement was to be able to look at a collection of microbes through a microscope and identify the specific

  bacteria which caused a specific disease. The individual

  bacteria could then be used to develop a vaccine.
• · Staining Bacteria - Koch developed a way to stain the

  microbes in the Petri dish with special dyes so he could

  see them more clearly under a microscope.
• · Photography - Photography was just invented. He used

  the new Zeiss lens it to prove his findings and his images ,

  inspired others.
