25
Robert Hooke
coined "cell", first to see microorgs
26
Antonie van Leeuwenhoek
dutch fabric merchant using hand made lens to count thread found many detailed microscopic observations
27
spontaneous generation debate
life rapidly appears from non-living things (abiogenesis)
28
biogenesis
living things originate from other living things
29
aristotle
early naturalist who favored spontaneous generation
30
Francesco Redi
Italian philosopher, disproved spontaneous generation of maggots with covered meat dish
31
Louis Joblot
French mathematician heated covered and uncovered hay wayer and found dust contamination
32
John Needham
English scientist boiled chicken broth, poured into clean and covered flash, saw growth occurred even when covered
33
Lazzaro Spallanzani
Italian Priest repeated Needham's experiment but with a originally sealed flash and saw no growth in the sealed flash disproving Needham
34
Franz Schulze and Theodor Schwann
German biologists treated incoming gas with heat or chemicals after oxygen was discovered and saw no grown (not oxygens doing but something in oxygen?)
35
Louis Pasteur
Used swan-neck flasks that allow oxygen in but traps dust particals are the deck, proving that oxygen doesnt grow microbes but that there is microbes in dust
36
endospores
asexual pores found in microbes
37
John Tyndall
english physicist described heat-resistant microbes (endospores)
38
Ferdinand Cohn
German botanist discovered and described endospores in some soil bacteria
39
Oliver Wendell Holmes
American Physician obeserved apparent spread of puerperal fever, work does before germ theory was recognized
40
Ignatz Semmelweiss
Vienna physician forced handwashing with chlorinated lime colutions and saw decrease in death/sepsis
41
John Snow
British doctor studied Cholera outbreak in Soho and tracked its outbreak to contaminated drinking water (Epidemiology)
42
Beginning of germ theory
discovered by Louis Pasteur as he was hired to find out why wine was going sour. discovered that if wine can be infected, so can humans!
43
Joseph Lister
Applied germ theory and used Carbolic acid (phenol) to clean hands, wounds, and operating rooms. saw reduction of infections and sepsis
44
Robert Koch
German Microbiologist worked to discover what microbes causes what diseases and described several postulates for the cause of disease
45
Koch's first postulate
the suspected pathogenic org should be present in all cases of the disease and absent from healthy animal
46
Koch's second postulate
the suspected org should be grown in pure curlture
47
Koch's third postulate
cells from a pure culture of the suspected org should cause disease in a healthy animal
48
Koch's fourth postulate
the org should be reisolated and shown to be the same as the original
49
Taxonomy
the science of classifying living things (KPCOFGS) Kingdom-Phylum-Class-Order-Family-Genus-Species
50
Carl Von Linne
began systematically classifying living things
51
Binomial
every org has a two-name designation- Genus species
52
5 Kingdom Model
Robert Whittaker 1. animals 2. plants 3. fungi 4. protists 5. Monera
53
New Phylogeny
Carl Woese three "Domains" 1. Archaea 2. Bacteria 3. Eukarya
