Branch of science that concerns the study of organisms. Woese"s phylogenetic tree of life simplified the five kingdoms into three domains: Important faces of in the history of microbiology: Lensmaker that discovered the ability to view organisms invisible to the naked eye with the use of a lense. Later went along to create a microscope. Put to question the theory that these organisms appear (cid:498)out of thin air(cid:499) Similar to redi, the two tested the manner in which organisms form by developing an experiment with meat both. One left their portion of both covered, while the other left his uncovered. The uncovered showed growth, while the covered showed none. Put to rest the argument that organisms can spontaneously appear. The thought that microorganisms are the cause many forms of disease. Created a stain detects peptidoglycan that separates bacteria into two large groups - gram positive/negative- Improved hygiene techniques that decreased occurrence of puerperal fever in birthing mothers.
