Louis Pasteur - Showed microbes caused fermentation and spoilage; Disproved spontaneous generation of microorganisms; Developed pasteurization; Demonstrated what is now known as Germ Theory of Disease; Developed a rabies vaccine
Robert Koch - Established Koch’s postulates (a sequence of experimental steps that verified the germ theory); Identified cause of anthrax, TB, and cholera; Developed pure culture methods
Both can be regarded as "fathers" of modern microbiology, particularly because the techniques/methods that they developed are still in use today.
lol, I was examined on this about 2 weeks ago and I can't remember all the details. What I do remember is that Koch and his Postulates went a long way to proving that germs caused disease (rather than miasmas, demons, or spells, etc). He made a bunch of 'rules' e.g. a germ or whatever extracted from a host and cultured, and then re-introduced to another host should cause the same disease that was in the first host for it to be qualified as having caused that disease in the first place. There were several other rules which we now can see are pretty basic, but for his time they were quite novel. Don't quote me on this one, but I think Pasteur (in addition to discovering pasteurization of milk and some stuff to do with brewing beer... presence of yeast I guess), proved that 'spontaneous generation' was false. Meaning that something can't come from nothing. I think it was him anyways, (but let's assume it was :-)) He had a flask with broth in it and had a long, thin, bent tube attached to a stopper in the neck of the flask. He left the apparatus like that and predictably nothing happened. Then he tilted the flask so that some of the broth settled in the bent tube closer and therefore exposed to air (O2) and stuff started to grow. I guess that proved that something in the broth needed O2 to multiply/grow and so he rubbished the idea that mould, etc just arrived from thin air (or else it would have grown in the bent tube before he tilted in the broth).
I managed to get my child to school on time.(thats always the biggest accomplishment of my day) Then I drank an entire pot of coffee. After that, I went down to the local coffee cafe' and drank another 20oz of coffee with a friend while we planned our takeover of the world...(its still a work in progress) I then spent the next few hours doing paper work and making phone calls. Oh, I also went to see a few new foreclosures on the market. After that I came home and thought about doing some laundry...it didn't go any further than that...I just thought about it. Finally I made some dinner, helped with homework, played some guitar hero (with the child), read a little, put the child to bed....and now I am here... what did you do?
